Procedure for TIG 4 TIME 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 begins. The current will go to the base value
selected with the bC button (ref.15 page 9).
4) When the torch button is released the current will go to the set value A with a
slope up value as selected with the SU button (ref.8 page 9).
End of welding:
1) Press the torch button: the current gradually falls with the time set by means of
the Sd button (ref.14 page 9); the arc remains at the final current value set with the
bC button (ref. 15 page 9).
2) Release the torch button: the arc goes out and then there will be the POST-
GAS time set by means of the PG button (ref.17 page 9).
Procedure for TIG 4 TIME 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
button (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.
3) Press the torch button: gas will come out immediately, lift the torch from the
side so as to move slightly away from the piece to be welded and start the welding
process; the current will go to the base value selected with the bC button (ref.15
page 9).
4) When the torch button is released the current will go to the set value A with a
slope up value as selected with the SU button (ref.8 page 9).
End of welding:
1) Perform the same procedure described for TIG 4 TIME welding with HF start.
