CONNECTIONS AND RECOMMENDATIONS
TIG DC requires gas protection (Argon).
• TIG LIFT
Activating the TIG Lift mode and setting the intensity:
TIG
DOWNSLOPE feature: this is the time during which, after the downslope, the current is going down until the arc
stops completely. This feature prevents craters and cracks at the end of the weld.

When the machine is in MMA Pulsed mode with HOT START feature:
• Press shortly the switch (5) to set the frequency.
• «FrE» (FREQUENCY) is displayed and then a number is displayed.

0,4 - 20 Hz
• Set the desired frequency (Hz) using the keys (4).
• The machine is ready to operate.
OK
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 (–). (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 and setting the intensity (see paragraph: TIG LIFT).
6. Set the gas flow on the gas bottle regulator, then open the torch valve.
7. To start the arc : make contact between the electrode and the workpiece.
8.At the end of the weld: lift the torch quickly (up-down) to activate the automated
downslope (see paragraph below). This movement must be done at a height between
5 and 10 mm. Then close the torch valve to stop the gas after the electrode has cooled
down.
When the machine is in MMA Pulsed mode:
• Press the switch (5) for 3 seconds.
• «tIG» (TIG) blinks and a number is displayed (display (1)).
• Set the desired intensity using the keys (4).

OK
When the machine is in TIG LIFT mode:
• Press shortly the switch (5) to set the duration of the progressive arc
reduction.
• «dSt» (DOWNSLOPE) blinks and a number is displayed

1 - 10 s / OFF • Set from 1 to 10 seconds, with the possibility to desactivate it (OFF).
• Validate by pressing the switch (5).
• The machine is ready to operate.
