Advice:
Low Hot Start: for thin metal sheets
High Hot Start for metals that are difficult to weld (dirty or oxidized parts).
To set the Hot Start, follow these steps:
Press the switch (5).
«HS» (Hot Start) blinks and a number is displayed.
Set the desired percentage (display (1)) using the (4) keys.
Validate by pressing the switch (5).
TUNGSTENE ELECTRODE WELDING UNDER INERT GAS (TIG MODE)
The DC TIG welding requires a protective gas (argon)
Follow the steps as below:
- Connect the earth clamp on the positive pole (+).
- Connect a torch «valve» negative polarity (-).(Ref. 044425)
- Connect the pipe gas torch on the gas cylinder
- Select the TIG position (3) using the selector button (5) (press and hold for 3 sec).
- Adjust the wished current (display (1)) using the keys (4).
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.
- To boot : Touch the electrode on the welding part
- 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, 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. 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).
