2.5 PREPARING FOR TIG WELDING
NOTE: For the cooler to power source assembly procedure refer
to the cooler instruction manual.
1. Set the welding power source ON/OFF switch to “O” (unit de-
energized).
2. Plug the power cable plug into a mains socket outlet.
3. Connect the gas hose from the welding gas cylinder to the rear
gas socket.
4. Open the cylinder gas valve.
5. Choose the electrode based on the type of material and thickness
of the workpiece to be welded.
6. Insert the electrode in the TIG torch.
7. Connect the torch plug to the welding socket on the basis of the
polarity required by the type of electrode in question.
8. Connect the plug of the ground clamp to the welding socket on the
basis of the polarity required.
9. Connect the gas hose from the welding torch to the front gas
socket.
10. Couple the welding torch connector to the TIG torch signals
connector.
11. Connect the earth clamp to the workpiece being processed.
12. Set the welding power source ON/OFF switch to “I” (unit
powered).
13. Select the following welding mode on the user interface: TIG DC /
TIG AC
14. Press the torch trigger with the torch well clear of any metal parts.
This serves to open the gas solenoid valve without striking the
welding arc.
15. Use the flow control valve to adjust the flow of gas as required
while the gas is flowing out.
16. Set the required welding parameter values on the user interface.
When the remote control pedal is connected and the relative
locking screw is tightened the welding current will vary in relation
to the pressure exerted on the pedal.
The system is ready to start welding.
