Technical data

The general technical data of the system are summarized in

table 1.

Usage limits (IEC 60974-1)

The use of a welder is typically discontinuous, in that it is made

up of effective work periods (welding) and rest periods (for the

positioning of parts, the replacement of wire and underflushing

operations etc. This welder is dimensioned to supply a I2max

nominal current in complete safety for a period of work of X%

of the total usage time. The regulations in force establish the

total usage time to be 10 minutes. The work cycle is considered

to be X% of this period of time. When the work cycle permit-

ted is exceeded a trip switch trips, which protects the welding

power source’s internal components against dangerous over-

heating and prevents incorrect functioning of the welding power

source.After several minutes the overheat cut-off rearms auto-

matically and the welder is ready for use again (Automatic re-

set error). This equipment is built to have a protection level of

IP 23 S, which means:

•

That it is protected against the penetration of solid foreign

bodies with diameters in excess of Ø 12 mm.

•

That it is protected against water spray hitting the surface

with an angle of incidence up to 60°.

• That the equipment has been tested for withstanding harm-

ful effects due to water getting in when the moving parts on

the equipment are moving.

WARNING: This equipment does not comply with EN/IEC 61000-3-12. If it is connected to a public low voltage system, it is the responsibility

of the installer or user of the equipment to ensure, by consultation with the distribution network operator if necessary, that the equipment may

be connected.

How to lift up the welding power source

The welding power source has a strong handle all in one with

the frame, used for transporting the welding power source man-

ually only.

NOTE: These hoisting and transportation devices conform to

European standards. Do not use other hoisting and transpor-

tation systems.

Open the packaging

Upon receiving the system:

•

Remove the welding power source and all relevant accesso-

ries-components from their packaging.

• Check that the welding power source is in good condition, if

not report any problems immediately to the seller-distributor.

• Make sure all ventilation grilles are open and that no foreign

bodies are blocking the air circulation.

Installation and connections

The installation site for the system must be carefully chosen

in order to ensure its satisfactory and safe use. The user is re-

sponsible for the installation and use of the system in accord-

ance with the producer’s instructions contained in this manual.

Before installing the system the user must take into consider-

ation the potential electromagnetic problems in the work area.

In particular, we suggest that you should avoid installing the

system close to:

• Signalling, control and telephone cables.

• Radio and television transmitters and receivers.

• Computers and control and measurement instruments.

• Security and protection instruments.

Persons fitted with pace-makers, hearing aids and similar

equipment must consult their doctor before going near a weld-

ing power source in operation. The equipment’s installation

environment must comply to the protection level of the frame

i.e. IP 23 S (IEC 60529 publication). The system is capable of

working in environments where working conditions are partic-

ularly hard.

This system is cooled by means of the forced circulation of air,

and must therefore be placed in such a way that the air may

be easily sucked in and expelled through the apertures made

in the frame.

The equipment must be assembled as follows:

• Mount on the trolley (optional extra).

• Fix the welding unit to the trolley.

• Connect the welding welding power source to the utility line.

• Connect up the welding cables.

Connecting the welding welding

power source to the utility line

Connection of the welding power source to the user line

(electrical current) must be performed by qualified per-

sonnel.

Before connecting the welding welding power source to

the mains power supply, make sure that rated voltage and

frequency correspond to those provided by the mains pow-

er supply and that the welding welding power source’s

power switch is turned to “O”.

Connection to the power supply must be carried out using the

tripolar cable supplied with the system, of which:

•

2 conducting wires are needed for connecting the welding

power source to the supply.

•

The third, which is YELLOW GREEN in colour is used for

making the “GROUND” connection.

Connect a suitable load of normalised plug (2p + e) to the

power cable and provide for an electrical socket complete

with fuses or an automatic switch. The ground terminal

must be connected to the ground conducting wire (YEL-

LOW-GREEN) of the supply.

Table 2 shows the capacity values that are recommended for

fuses in the line with delays.

NOTE: Any extensions to the power cable must be of a suita-

ble diameter, and absolutely not of a smaller diameter than the

special cable supplied with the welding power source.

• Thread the end of the wire into the back guide (Pos. 7, Fig.

B) on the drawing mechanism.

• Lift up the idle roller Ø 26 mm (Pos. 1, Fig. B) releasing the

roller pressure mechanism (Pos. 6, Fig. B). Check that the

drive roller (Pos. 4, Fig. B) has the diameter corresponding

to the wire being used printed on the outer side.

• Thread the wire into the central wire guide and into the wire

guide of the centralized attachment (Pos. 3, Fig. B) for a few

centimetres. Lower the idle roll-holder arm making sure the

wire goes into the slot of the drive roll. If necessary, adjust the

pressure between the rollers with the screw provided (Pos.

5, Fig. B). The correct pressure is the minimum that does not

allow the rollers to skid on the wire. Excessive pressure will

case deformation of the wire and tangling on the entrance of

the sheath; insufficient pressure can cause irregular welding.

Assembly of drive roller

Follow instructions given below for mounting the drawing roll-

er onto the mechanism:

• Unscrew the screw (Pos. 5, Fig. B).

• Lift up the idle roll-holder arm Ø 26 mm (Pos. 2, Fig. B).

•

Each roller shows the type of wire and diameter on the two

external sides.

•

Mount the appropriate roller (Pos. 4, Fig. B) making sure the

groove is in the right position for the diameter of the wire be-

ing used.

• Screw the screw (Pos. 5, Fig. B).

MIG-MAG welding with GAS

To begin MIG-MAG welding, carry out the following tasks (with

the welding power source switched off):

1 - Connecting the cables (Fig. C1-C2)

1) Connect the gas hose to the pressure reducer fitted on

the cylinder beforehand. Gas cylinders are supplied with

a pressure reducer to adjust pressure of the gas used for

welding.

2) Screw the torch to the centralised connection on the front

panel of the welding welding power source (Pos. 4, Fig.A).

3) Connect up the earthing system cable to the rapid cou-

pling marked by a - (negative) symbol and then the rel-

evant ground clamps to the piece being welded or to its

support in an area free from rust, paint and grease. Using

particularly long earthing cables reduces the voltage and

causes some problems from increased resistance and in-

ductance of the cables that could cause faulty welding. Fol-

low instructions to avoid these problems:

•

Use earthing and extension cables with appropriate sec-

tion.

• Lay out the cables as a flat as possible to prevent them

from coiling up.

4) Open the moving cover, remove the protection box for

changing polarity (see Fig. C2) and make sure that the

change polarity cable is connected to the positive pole (+).

2 - Welding

1) Open the moving cover and fit the coil of wire.

2) Load the wire (see the “Loading the wire” paragraph).

3) Switch the welding welding power source on by moving the

power supply switch to I(Pos. 5, Fig. A).

4) Carry out the following operations on the MIG-MAG torch:

•

Remove the gas-guide and wire-guide nozzles, allowing

the wire to flow freely during loading. Remember that the

contact tip must correspond to the wire diameter.

•

Push the torch push button or the motor check push but-

ton until the wire end comes out from the torch.

• Tighten the contact tip on the torch.

• Attach the correct gas-guide nozzle.

• Protect the gas-guide nozzle and the wire-guide nozzle

of the torch from sprays of solder.

5) Make the adjustments and select the parameters on the

control panel.

6) Open the tap on the cylinder slowly and adjust the reduc-

er knob to obtain a pressure of about 1,0 to 1,5 bar, and

regulate the flow to about 15 lit/min (to suit the current to

used for welding).

7) The welding welding power source is ready for welding. To

begin welding, approach the point to be welded and press

the button on the torch.

8) When you have finished welding, remove the waste, turn

off the welding power source and close the gas cylinder.

MIG-MAG welding without GAS

To begin MIG-MAG welding without gas, carry out the following

tasks (with the welding power source switched off):

1 - Connecting the cables (Fig. D1-D2)

1) Screw the torch to the centralised connection on the front

panel of the welding welding power source (Pos. 4, Fig.A).

2) Connect up the earthing system cable to the rapid cou-

pling marked by a + (positive) symbol and then the relevant

ground clamps to the piece being welded or to its support in

FIG. C2

FIG. C1

2000HB98

an area free from rust, paint and grease. Using particularly

long earthing cables reduces the voltage and causes some

problems from increased resistance and inductance of the

cables that could cause faulty welding. Follow instructions

to avoid these problems:

•

Use earthing and extension cables with appropriate sec-

tion.

• Lay out the cables as a flat as possible to prevent them

from coiling up.

3) Open the moving cover, remove the protection box for

changing polarity (see Fig. D2) and move the change po-

larity cable, connecting it to the negative pole (-).

2 - Welding

1) Open the moving cover and fit a coil of wire with a core for

welding without using gas.

2) Load the wire (see the “Loading the wire” paragraph).

3) Switch the welding welding power source on by moving the

power supply switch to I(Pos. 5, Fig. A).

4) Carry out the following operations on the MIG-MAG torch:

•

Remove the gas-guide and wire-guide nozzles, allowing

the wire to flow freely during loading. Remember that the

contact tip must correspond to the wire diameter.

•

Push the torch push button or the motor check push but-

ton until the wire end comes out from the torch.

• Tighten the contact tip on the torch.

• Attach the correct gas-guide nozzle.

• Protect the gas-guide nozzle and the wire-guide nozzle

of the torch from sprays of solder.

5) Make the adjustments and select the parameters on the

control panel. Make sure that you have selected a program

that is suitable for wire with a core.

6) The welding welding power source is ready for welding. To

begin welding, approach the point to be welded and press

the button on the torch.

7) Once welding has been completed remove the slag and

switch off the welding power source.

Spot welding

FIG. E

Welding can be done with or without gas. The substantial dif-

ference with MIG-MAG welding is essentially related to the

torch and the adjustments that must be made on the TS con-

trol panel.

• Depending on the torch chosen and the work to be done, a

gas guide nozzle can be fitted on the torch that is specifical-

ly for spot welding (see Fig. E).

• Use the control panel to select the spot-welding mode and,

if necessary, make the changes to the related “Special func-

tions - Fx”, which allows the welding power source to do this

specific type of welding.

To begin spot welding:

•

Place the gas guiding nozzle perpendicular on the workpiece

to be spot welded.

•

Press the torch button to start the welding current and wire

feed.

•

When the spot welding time expires (SPOT WELD TIME),

the wire feed stops automatically.

•

When the torch button is pushed again a new welding cy-

cle starts.

• Release the torch button.

FIG. D1

FIG. D2

2000HB99

FIG. F

Interval welding (Stitch)

The substantial differences with the spot welding mainly con-

cern the adjustments that must be carried on the welding weld-

ing power source.

Use the control panel to select the interval welding mode and

then make the changes to the related “Special functions - Fx”,

which allows the welding power source to do this specific type

of welding.

To begin interval welding:

•

Press the torch button to start the welding current and wire

feed.

•

At this point the welding welding power source automatically

carries out a succession of welded portions (STITCH WELD

TIME) followed by a pause (STITCH WELD PAUSE), ac-

cording to the times entered previously. This procedure stops

automatically only when the TORCH BUTTON is released.

•

When the torch button is pushed again the torch begins a

new interval welding cycle.

Aluminium welding

To weld with aluminum wire proceed as follows:

•

Replace the drive roller with the appropriate for aluminum

wire.

•

We recommend to use a torch set with maximum lenght of

3 m and a capillary liner, e.g. DIX DSK 2-xx.

•

Set the pressure between the drive rollers at the minimum,

by turning the screw provided.

• Use argon gas at a pressure of 1,3 - 1,7 bar.

TIG welding with “Lift”

In the TIG process welding is achieved by melting the two metal

pieces to be joined, with the possible addition of material from

the outside, using an arc ignited by a tungsten electrode. The

“Lift” (TCS) type ignition used in the equipment makes it pos-

sible to reduce tungsten inclusions on ignition to a minimum.

The molten bath and the electrode are protected by and inert

gas (for example,Argon). This type of welding is used to weld

thin sheet metal or when elevated quality is required.

1) Connecting the welding cables (Fig. F):

•

Connect one end of the gas hose to the gas connecter on

the TIG torch and the other end to the pressure reducer

on the inert gas cylinder (Argon or similar).

• With the welding power source switched off:

Connect the ground cable to the snap-on connector

marked + (positive).

Connect the relative ground clamp to the workpiece or

to the workpiece support in an area free of rust, paint,

grease, etc..

Connect the TIG torch power cable to the snap-on con-

nector marked - (negative).

2) Switch the welding welding power source on by moving the

power supply switch to I(Pos. 5, Fig. A).

3) Make the adjustments and do the parameter settings on

the control panel.

4) Open the gas cylinder and regulate the flow by adjusting

the valve on the TIG torch by hand.

5) Ignite the electric arc by contact, using a decisive, quick

movement without dragging the tungsten electrode on the

piece to be welded (“Lift” type ignition - Fig. G).

6) The welder has a SWS “Smart Welding Stop” system for

the end of TIG welding. Lifting up the torch without switch-

ing off the arc will introduce a slope down and it will switch

off automatically.

7) When you have finished welding remember to shut the

valve on the gas cylinder.

Table 3 shows the currents to use with the respective elec-

trodes for TIG DC welding. This input is not absolute but is for

your guidance only; read the electrode manufacturers’instruc-

tions for a specific choice. The diameter of the electrode to use

is directly proportional to the current being used for welding.

Electrode welding (MMA)

Electrode welding is used to weld most metals (different types

of steel, etc.) using coated rutilic and basic electrodes with di-

ameters ranging from Ø 1.6 mm to Ø 3,2 mm.

1) Connecting the welding cables (Fig. H):

Disconnect the welding power source from the mains pow-

er supply and connect the welding cables to the output

terminals (Positive and Negative) of the welding welding

power source, attaching them to the clamp and ground

with the polarity specified for the type of electrode being

FIG. G

2000HA86

used (Fig. H). Always follow the electrode manufacturer’s

instructions. The welding cables must be as short as pos-

sible, they must be near to one another, positioned at or

near floor level. Do not touch the electrode clamp and the

ground clamp simultaneously.

2) Switch the welding welding power source on by moving the

power supply switch to I(Pos. 5, Fig. A).

3) Make the adjustments and select the parameters on the

control panel.

4) Carry out welding by moving the torch to the workpiece.

Strike the arc (press the electrode quickly against the met-

al and then lift it) to melt the electrode, the coating of which

forms a protective residue. Then continue welding by mov-

ing the electrode from left to right, inclining it by about 60°

compared with the metal in relation to the direction of weld-

ing.

PART TO BE WELDED

The part to be welded must always be connected to ground

in order to reduce electromagnetic emission. Much attention

must be afforded so that the ground connection of the part to

be welded does not increase the risk of accident to the user or

the risk of damage to other electric equipment. When it is nec-

essary to connect the part to be welded to ground, you should

make a direct connection between the part and the ground

shaft. In those countries in which such a connection is not al-

lowed, connect the part to be welded to ground using suitable

capacitors, in compliance with the national regulations.

WELDING PARAMETERS

Table 4 shows some general indications for the choice of elec-

trode, based on the thickness of the parts to be welded. The

values of current to use are shown in the table with the respec-

tive electrodes for the welding of common steels and low-grade

alloys. These data have no absolute value and are indicative

data only. For a precise choice follow the instructions provided

by the electrode manufacturer.

The current to be used depends on the welding positions and

the type of joint, and it increases according to the thickness and

dimensions of the part.

The current intensity to be used for the different types of weld-

ing, within the field of regulation shown in table 5 is:

• High for plane, frontal plane and vertical upwards welding.

• Medium for overhead welding.

•

Low for vertical downwards welding and for joining small pre-

heated pieces.

Afairly approximate indication of the average current to use in

the welding of electrodes for ordinary steel is given by the fol-

lowing formula: I = 50 × (Øe - 1)

Where:

I = intensity of the welding current

Øe = electrode diameter

Example:

For electrode diameter 4 mm

I = 50 × (4 - 1) = 50 × 3 = 150A

Maintenance

ATTENTION: Cut off the power supply to the equipment be-

fore effecting any internal inspection.

DIX PI GO 1156.M

IMPORTANT: Since the welding welding power sources are ful-

ly electronic, removing the dust that is sucked into the welding

power source by the fans, is of utmost importance.

In order to achieve correct functioning of the welding power

source, proceed as described:

•

Periodic removal of accumulations of dirt and dust inside the

equipment using compressed air. Do not point the jet of air

directly at the electrical parts as this could damage them.

•

Periodical inspection for worn cables or loose connections

that could cause overheating.

•

Make sure the air circuit is completely free of any impuri-

ties and that the connections are tight and free of any leaks.

In this connection, inspect the solenoid valve very carefully.

•

Check the wire feeder rolls periodically and replace them

when wear impairs the regular flow of the wire (slipping etc).

TORCH

The torch is subjected to high temperatures and is also stressed

by traction and torsion. We recommend not to twistthe wire and

not to use the torch to pull the welder. As a result of the above

the torch will require frequent maintenance such as:

• Cleaning welding splashes from the gas diffuser so that the

gas flows freely.

• Substitution of the contact point when the hole is deformed.

•

Cleaning of the wire guide liner using trichloroethylene or

specific solvents.

• Check of the insulation and connections of the power cable;

the connections must be in good electrical and mechanical

Original spares have been specifically designed for our equip-

ment. The use of spares that are not original may cause vari-

ations in the performance and reduce the safety level of the

equipment. We are not liable for damage due to use of spare

parts that are not original.

FIG. H

The pointing out of any difficulties

and their elimination

The supply line is attributed with the cause of the most com-

mon difficulties. In the case of breakdown, proceed as follows:

1) Check the value of the supply voltage.

2) Check that the power cable is perfectly connected to the

plug and the supply switch.

3) Check that the power fuses are not burned out or loose.

4) Check whether the following are defective:

• The switch that supplies the welding power source.

• The plug socket in the wall.

• The mains switch.

NOTE: Given the required technical skills necessary for the

repair of the welding power source, in case of breakdown we

advise you to contact skilled personnel or our technical ser-

vice department.

• Remove both the adjustment knobs.

• Disconnect the electrical connectors for the board.
