3 INTRODUCTION

CAUTION! All warranty undertakings of the supplier cease to apply if the

customer attempts to rectify any faults on the machine during the

warranty period.

3.1 Generally

The DTG 405 is a welding rectifier with inverter technology for TIG- and electrode

welding. Welding with direct current as well as with alternating current is possible.

Theinvertertechnologyhasadvantagessuchaslowpowerconsumption,lightweightand

small dimensions.

Advanced power electronics provide fast welding current control and high class welding

current properties.

3.2 Delivery list

DTG 405 is delivered with:

•5 m of powercable

•5 m of workpiece cable

•1.8 m of gas hose and 2 hose clamps.

ARC WELDING AND CUTTING CAN CAUSE INJURY TO YOURSELF AND OTHERS. TAKE

PRECAUTIONS WHEN WELDING. FOLLOW YOUR EMPLOYERS SAFETY PRACTICES WHICH

ARE BASED ON MANUFACTURERS HAZARD DATA.

ELECTRIC SHOCKS- Can kill.

• Install and earth the welding unit in accordance with the appropriate standards.

• Do not touch live electrical parts or electrodes with bare skin, wet gloves or wet clothing.

• Insulate yourself from earth and the workpiece.

• Ensure your workplace is safe.

FUMES AND GASES - Can be dangerous to health.

• Keep your head out of the fumes.

• Use ventilation, extraction at the arc, or both, to extract fumes and gases from your breathing

zone and the general area.

ARC RAYS - Can injure eyes and burn skin.

• Protect your eyes and body. Use the correct welding screen and filter lens and wear protective

clothing.

• Protect bystanders with suitable screens or curtains.

FIRE HAZARD

• Sparks (spatter) can cause fire. Make sure therefore that there are no inflammable materials

nearby.

NOISE - Excessive noise can damage hearing.

• Protect your ears. Use ear defenders or other hearing protection.

• Warn bystanders of the risk.

MALFUNCTION - Call for expert assistance in the event of malfunction.

PROTECT YOURSELF AND OTHERS!

WARNING

READ AND UNDERSTAND THE OPERATING MANUAL BEFORE INSTALLING OR OPERATING.

3.3 Technical Data

Relative duty cycle

The relative duty cycle shows the time in percent of a period of ten minutes in which one

could weld with a given current intensity without overloading the welding power source.

Application

The sign signifies that the welding current source is constructed for working in rooms

with raised electrical endangering.

Enclosure

The IP code indicates the enclosure, i. e. the degree of protection against penetration by

solid objects and water. Devices with the sign IP 23 is designed for operating outside as

well as for working indoors.

4 INSTALLATION

4.1 Generally

The installation must be done by a specialist.

4.2 Location and Connection

To reduce the voltage drop when using a long cable, it is advisable to select cable with

larger cross section.

•Locate the welding power source so that both the inlet and outlet vents for air cooling

are free from obstruction.

•Connect protective gas

•Connect TIG torch and return cable, alternative welding cable and return cable of the

electrode holder (see fig. page 80).

•Make sure that the welding power source is connected to the correct mains voltage

and is appropriately protected. Protective earthing in accordance with applicable

instructions should be ensured.

The rating plate with the connection dates are located on the back of the welding

power source .

Now the machine is ready for welding.

WARNING

This product is intended for industrial use. In a domestic environment this product

may cause radio interference. It is the user responsability to take adequate

precautions.

5 OPERATION

5.1 Generally

Generaly safety instructions for the operation of the welding device are found on page 76.

Read the instructions before using the welding device.

5.2 Control installations and connections

Caution! The Positions F and G are omitted in versions with a central connection.

5.3 Remote control

The welding current during the TIG- and electrode welding can be adjusted using the

remote regulator.

With the remote regulator, any current between 3 A and the preset welding current I2 of

the unit can be selected.

5.4 Overheating protection

•An integrated thermal cut-out in the welding device protects the equipment from

overheating.

•The welding process is interrupted and the fault display (16) indicates error "4" .

•The equipment must be left in that condition to cool with the main switch left in the on

position and the cooling fans running.

CAUTION! When the error indicator "4" disappears, the position "Electrode" has to be

set to the open circuit voltage on the electrode; on position "TIG" the

welding device can now be started with the torch button. After cooling, the

device is reconnected automatically.

Care must be takento ensure that the electrode does not touch the welding

table, the workpiece or any other electrical conducting object during the

cooling phase of the power source in order to prevent unintentional arc igni-

tion when switching it on again.

An unintentionally ignited arc may damage the electrode holder, the

workpiece or the equipment.

12 LED,

ramp down Displays the ramp down phase (Down-Slope).

13 Rotary switch,

ramp down Sets the rate at which the welding current I2 ramps down to the

drop-off current I3 at the end of throat. The ramp down prevents

cratering.

14 Button, gas

test In order to manually purge the hose bundle with protective gas.

Pressing this button opens the gas valve without applying a welding

voltage to the electrode.

During pulsed operation: When activating the button gas test, the

display (10) switches to the I4 value.

15 Display,error

code Display of possible error messages.

message appears in the error display.

17 Rotary switch,

gas post-flow

time

Sets the gas post-flow time after finishing welding to protect the

weldpool. The time can be set from approximately 0.2 to 30s.

18 Rotary switch,

AC frequency Continuous setting of the AC frequency from 50 Hz up to 200 Hz.

19 LED, final

current I3 LED illuminates when the final current I3 is active.

20 Rotary switch,

AC balance If the rotary switch is set to the middle position, the positive and the

negative half cycles are equal for AC welding.

This rotary switch is deactivated, when welding using DC current (DC

operation).
