TIG µP 261H - 263H
TECHNICAL DESCRIPTION
To deactivate AC mode, hold down the PULSE MODE button (ref.19 page 9) for more
than 2 seconds.
7) In this mode you can regulate the base pulse current. When the bC button (ref.15
page 9) is pressed, the right-hand display A (ref.20 page 9) will start to blink indicating
the value of the final welding current A, which may be regulated with the encoder (ref.5
page 9) from 10% to 90%.
8) 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 2 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) close to the piece to be welded.
3) Press the torch button: after 0.25 seconds of PRE-GAS, the arc is lit by the HF
generator and the welding process begins.
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 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 2 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: after 0.5 seconds of PRE-GAS, lift the torch from the side so
as to move slightly away from the piece to be welded and start the welding process.
End of welding:
1) Perform the same procedure described in TIG 2 TIME welding with HF start.
- TIG 4 TIME WELDING
1) Press the select mode button (ref.4 page 9) until the Tig 4T mode led (ref.4C
page 9) lights up.
2) The letters tig 4t 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 slope UP - Pressing the SU button (ref.8 page 9) selects the
time of the slope up. The right-hand display A (ref.20 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.
5) Regulating the slope down – proceed as described for TIG 2 TIME welding.
6) Regulating the base current - When the bC button is pressed (ref.15 page
9), the right-hand display A (ref.20 page 9) will start to blink, indicating the value
that can be selected with the encoder (ref.5 page 9) from 10% to 90% of the
welding current A.
To view the set value at any time, briefly press the bC button.
7) Regulating the post-gas time - proceed as described for TIG 2 TIME
welding.
