TIG µP 253H AC/DC
TECHNICAL DESCRIPTION
To view the set value at any time, briefly press the FC 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 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: gas will come out immediately.
4) When the torch button is released the arc will be lit by the HF generator; the cur-
rent 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 SL 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.10 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 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.
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:
