2.5 PREPARING FOR TIG WELDING
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. Choose the electrode based on the type of material and thickness
of the workpiece to be welded.
4. Insert the electrode in the TIG torch.
5. Connect the torch plug to the welding socket on the basis of the
polarity required by the type of electrode in question.
6. Connect the plug of the ground clamp to the welding socket on
the basis of the polarity required.
7. Connect the earth clamp to the workpiece being processed.
8. Set the welding power source ON/OFF switch to “I” (unit
powered).
9. Select the following welding mode on the user interface: DC TIG
This model of welding machine has not been provided either with
the control for gas flow (solenoid valve) or with the torch button.
The system is ready to start welding.
LIFT-ARC WELDING
1. Open the torch valve to let the gas out.
2. Touch the workpiece with the torch electrode.
3. Slowly lift the torch to strike the arc.
The WELDING CURRENT reaches the preset value.
4. Quickly move the torch clear of the workpiece to extinguish the
welding arc.
5. Close the torch valve to interrupt the gas flow.
