GENERAL SPECIFICATIONS AND NOTES

FOR CONSULTING THIS MANUAL

The “DP231C” welders are made using

INVERTER technology. They are extremely

compact and versatile devices that can be used

in all those situations that require minimum

obstruction, combined with the highest

performance.

These welders use both manual and

synergic MMA, TIG and MIG/MAG (short arc,

pulse or double pulse).

The innovative operator interface system, which

uses a large 5,7” TFT colour screen, allows for

simple and intuitive use of the equipment, without

renouncing on the possibility to personalise all of

the welding settings.

All of the main parameters of the machine

are stored on a memory card (SD-Card), keeping

the equipment constantly up-dated with the

latest welding developments. If the memory card

is removed the equipment will cease to function,

providing an optimal antitheft system and

safeguard against inappropriate use. Thanks

to the advanced control techniques adopted,

the product is extremely reliable and easy to

use. This instruction manual provides detailed

information on the machine settings: reading the

entire manual will allow you to appreciate the

extreme exibility and practicality of use.

Caution: the device must only be used in the

manner and for the purpose described in this

manual. Never use inappropriately or for any

other purpose.

WELDING WIRE

To load the welding wire, follow these instructions

carefully, in the order described below. Warning:

before inserting the wire, always remove the gas

nozzle and the wire feeder tip from the welding

torch.

1. Disconnect the cable from the power supply

(18 of Fig. 2).

Caution: before proceeding with the next

step, make sure the torch cable (Fig. 4) is well

extended and that the welding wire does not

have any bends or burrs. Failure to follow these

precautions could damage the wire-feeding tube

inside the torch. Once the wire has been threaded

through the torch, attach the wire-feeder tip and

the gas nozzle.

N.B. When changing the diameter of the wire,

make sure that the correct cable of the wire-

feeder spool is facing towards the inside of the

machine. To do so, ensure that the diameter and

type of wire is legible (facing towards the outside

of the machine) Remember that the spools with

the centre of the

spool support of the

welding wire (22 of

Fig. 3).

3. If necessary,

depending on the

size of the spool

used, remove the

bearing spool.

4. Remove the

plastic wrap from the

new spool and place

the spool on the

appropriate support

(22 of Fig. 3).

4. Replace the ball-

grip knob.

5. Please note that

the hex socket (M8)

situated in the centre

of the spool support

is part of the wire

tension system.

6. Lower the roll

feeder (25 of Fig.

3A)

7. Insert the wire

into the inlet tube

(26 of Fig. 3A) of

the wire feeder

motor. .

8. Run the wire

under the wire

feeder spools all the

way to the out-let of

the Euroconnector.

a ‘V’ cable are suitable for feeding iron and

steel wire. The spools with a ‘U’ are suitable for

aluminium wire.

4. MIG/MAG WELDING To choose this welding

mode use switch 10, select MIG and press

conrm.

Switch 9 adjusts the machine power.

There are three principal MIG-MAG welding

modes:

1.Manual short arc

2.Synergic short arc

3.Pulsed arc synergic

4.1 Manual Short Arc MIG Welding

By turning switch 10 it is possible to choose from

the different MIG-MAG welding modes; press

the switch to select the desired option.

MIG/MAG welding (Metal Inert Gas and Metal

Active Gas) is continuous wire feed welding that

provides a higher current density compared to

welding with a uxcovered electrode; this allows

increased penetration and speed and the joint

can be lled with less strokes. Welding is carried

out by melting a metallic electrode, consisting of

a continuous wire, in a welding pool at a constant

speed, controlled by the welding torch. When

the wire starts to feed, it touches the area that

requires welding, creating an electric arc; the arc

melts the wire, which is then deposited on the

workpiece.

This welder can be used with the following types

of wire:

1. Solid wire: must always be used with a gas

shield.

2. Flux cored for gas welding: the centre of the

wire contains a mineral product that improves

the quality of the weld (this must always be used

with gas).

The correct method for connecting the torch and

the earth cable can be seen in the table below:

Once selected the follow screen will appear: Wire

speed: This sets the speed of the welding wire.

The welding current and the wire speed must be

adjusted, taking into consideration the thickness

of the workpiece. Larger pieces will require a

higher wire speed.

For best results, the wire speed must be adjusted

during welding.
