TUNGSTEN ELECTRODE WELDING WITH INERT GAS (TIG MODE)
CONNECTIONS AND RECOMMENDATIONS
TIG DC requires gas protection (Argon).
Recommended combinations / electrode grinding
0.3 - 3 mm
2.4 - 6 mm
4 - 8 mm
To optimise the welding process, it is recommended to grind the electrode prior to the welding, as described below:
L = 3 x d.
TROUBLESHOOTING
Troubleshooting
The 2 indicators are on, but the
machine does not deliver any cur-
rent.
The green indicator is on, but the
machine does not weld.
The product is under voltage, you
are feeling tingling when touching
the machine's body.
The machine welds poorly.

PROGYS 160 LA / 180 LA
To do TIG welding, follow these steps :
1. Connect the earth clamp to the positive connector (+).
2. Connect a valve torch to the negative connector (–) (option, ref. 044425)
3. Connect the torch gas hose to the gas bottle regulator.
It may be necessary to cut it before the nut if it is not suitable for the regulator.
4. Activating the TIG mode with the switch on the front panel and adjust the inten-
sity.
5. Set the gas flow on the gas bottle regulator, then open the torch valve.
6. To start the arc : make contact between the electrode and the workpiece.

Causes
Wait for the end of the cooling
cycle.
Switch off the unit (with the on/off
switch), then turn it on.
Check the connections
Check the plug and the earth of
your installation.
Check the polarity (+/-) recom-
mended on the electrode box.
