Advice: :
• Low Hot Start: for thin metal sheets
• High Hot Start for metals that are difficult to weld (dirty or oxidized parts)
• Remove the electrode from the electrode holder when the equipment is not used.

The DC TIG welding requires a protective gas (argon)
Follow the steps as below :
at a height of 5 to 10 mm. Then close the valve to stop the torch gas after cooling of the electrode.
Automatic Arc slope with time adjustable
Function activation:
This corresponds to the end of welding time required for the gradual decline in the welding current until the stop of the
arc. This function helps to avoid cracks and craters at end of welding.

1. Connect the earth clamp on the positive pole (+).
2. Connect a torch «valve» negative polarity (-).(Ref. 044425)
3. Connect the pipe gas torch on the gas cylinder
4. Select the TIG position (3) using the selector button
3 sec).
5. Adjust the wished current (display (1)) using the keys
Advice : Take 30A/mm as a default setting and adjust according to the part to weld.
6. Set the gas flow on flewmeter of the gas cylinder, and then open the valve of the
torch.
7. To boot : Touch the electrode on the welding part
8. At end of welding: Up 2 times the arc (up-down-up-down) to trigger the automatic
fade (see paragraph below). This movement must be performed in less than 4 sec,
1. Press the selector switch (5)
2. Set the automatic arc slope you wish from 1 to 10 sec (display(1)) using key
3. Validate the required figure by pressing the selector button (5).
