2.5 PREPARING FOR TIG WELDING

NOTE: For the cooler to power source assembly procedure refer to the cooler instruction man-
ual.
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. Connect 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: DC TIG
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 weld-
ing current will vary in relation to the pressure exerted on the pedal.
The system is ready to start welding.
