TIG µP 261H - 263H
TECHNICAL DESCRIPTION
5) Regulating the post-gas time - proceed as described for TIG 2 TIME
welding.
6) Activating and regulating DC pulse mode – proceed as described for TIG 2
TIME welding .
7) 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 SPOT 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 0.5 seconds of PRE-GAS, the arc is lit by the HF
generator and the welding process begins.
End of welding:
1) The arc switches off automatically after the time regulated with the SU button
(ref.8 page 9); then there will be the POST-GAS time set by means of the PG
button (ref.17 page 9).
Procedure for TIG SPOT 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 Spot welding with HF start.
- TIG WELDING WITH RESET (DOUBLE PARAMETER)
1) Press the mode select button (ref.4 page 9) until the Tig Reset mode led (ref.4E
page 9) lights up.
2) The letters rEP 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 down – proceed as described for TIG 2 TIME welding.
5) Regulating the base current – Second Parameter - 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), which
ranges from 10% to 90% of the final welding current A.
By pressing the torch button briefly (less than 0.5 seconds ), you can pass directly
from current value A to the final current value bC and vice versa.
To view the set value at any time, press the bC button.
