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.
Connect the gas hose from the welding gas cylinder to the relative
socket.
4.
Open the cylinder gas valve.
5.
Choose the electrode on the basis of the type of material to be
welded and the thickness of the workpiece.
6.
Insert the electrode in the TIG torch.
7.
Connect the TIG torch plug to the EURO TORCH welding socket
8.
Connect the plug of the polarity selector cable to the welding socket
on the basis of the polarity required.
9.
Connect the plug of the ground clamp to the welding socket on the
basis of the polarity required.
10.
Connect the earth clamp to the workpiece being processed.
11.
Set the welding power source ON/OFF switch to “I” (unit powered).
12.
Use the selector in the spool housing to select TIG welding mode.
13.
Select the torch trigger procedure on the user interface.
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..
17.
The system is ready to start welding.
