TECHNICAL TIG µP 203H-353H AC/DC
DESCRIPTION
4) When the torch button is released the arc will be lit by the HF generator; the
current will go to the set value A with a slope up value of 1/4 t with respect to the
time set for the slope down.
End of welding:
1) Press the torch button: the current gradually falls with the time set by means of
the ST button (ref.8 page 9); the arc remains at the final current value set with the
FC button.
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.15 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.
4) Release the torch button: 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
set value A with a slope up value of 1/4 t with respect to the time set for the slope
down.
End of welding:
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.20-21 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 ST button (ref.8 page 9)
selects the spot welding time. The left-hand display V (ref.21 page 9) 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 ST 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
PREPARING 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) .
