8) Activating and regulating DC pulse mode – proceed as described for TIG 2
TIME welding.
9) If you want to operate with a remote control (CAD), refer to the chapter on
PREPARING THE REMOTE/PEDAL/TORCH UP-DOWN CONTROL on page 20.
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 (ref.7A page 9) lights
up.
2) Bring the tip of the electrode (tungsten) into contact with 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 goes 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 an
up slope, with a value selected using the SU button (ref.8 page 9).
End of welding:
1) Release 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) close to 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 goes 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 an
up slope, with a value selected using the SU button (ref.8 page 9).
End of welding:
1) Perform the same procedure described in TIG 4 TIME welding with HF start.
- TIG SPOT WELDING
1) Press the select mode button (ref.4 page9) until the TIG SPOT WELDING
mode led (ref.4D page 9) lights up
2) The letters Pun will appear on the displays (ref.20-21 page 9) for 2 seconds .
3) Regulating the welding current – proceed as described for TIG 2 TIME
welding.
4) Regulating the spot welding time – Pressing the SU button SU (ref.8 page 9)
selects the spot welding time. The right-hand display A (ref.20 page ) will start to
blink, indicating 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 SU button.
