1) Perform the same procedure described for TIG 4 TIME welding with HF start.
- TIG spot welding
1) Press the mode selection button (ref.4 page 9) until the TIG SPOT WELDING
mode led lights up (ref.4D page 9)
2) For 2 seconds the displays (ref.15-16 page 9) will show the letters Pun.
3) Regulating the welding current – proceed as described for TIG 2 TIME welding.
4) Regulating the spot welding time – Pressing the SL button (ref.8 page 9) selects
the spot welding time. The left-hand display V (ref.15 page 9) will start to blink, in-
dicating the value that can be selected with the encoder (ref.5 page 9) from 0.1 to
10 seconds.
To view the set value at any time, briefly press the SL button.
6) Regulating the post-gas time - proceed as described for TIG 2 TIME welding.
7) Activating and regulating DC pulse – proceed as described for TIG 2 TIME
welding.
8) Activating and regulating AC mode – proceed as described for TIG 2 TIME
welding.
9) If you want to work with a remote control (CAD), refer to the chapter on PRE-
PARING THE REMOTE/PEDAL CONTROL on page 20.
Procedure for TIG SPOT WELDING with HF start
Starting welding :
1) Press the HF ON button (ref.7 page 9) ; the HF ON led lights up (ref.7A page
9) .
2) Bring the tip of the electrode (tungsten) close to the piece to be welded.
3) Press the torch button: after 0.5 seconds of PRE-GAS, the arc is lit by the HF
generator and the welding process starts .
End of welding:
1) The arc goes out automatically after the time regulated by means of the SL but-
ton (ref.8 page 9); then there will be the POST-GAS time set by means of the PG
button (ref.10 page 9).
Procedure for TIG SPOT WELDING with LIFT start (without HF)
Starting welding:
1) Check that the HF ON led (ref.7A page 9) is off. If it is not, press the HF ON but-
ton (ref.7 page 9) ; the HF ON led goes off (ref.7A page 9).
2) Bring the tip of the electrode (tungsten) into contact with the piece to be welded.
