TECHNICAL DESCRIPTION
indicating the value that can be selected with the encoder (ref.5 page 9) from 0.5s
to 30s.
To view the set value at any time, briefly press the PG button.
6) Activating and regulating DC pulse – A first brief press of the PULSE MODE
button (ref.19 page 9) selects pulse mode.
The ON led (ref.19A page 9) will start to blink. The displays will start to blink.
6a) Regulating the Pulse Frequency– Turning the regulating encoder F (ref.18
page 9) varies the frequency value from 0.4Hz to 300Hz; the right-hand display A
(F) (ref.20 page 9) indicates the value selected.
6b) Regulating the Pulse Duty-cycle– Turning the regulating encoder D (ref.16
page 9) varies the Duty-cycle value from 10% to 90%; the left-hand display V (D)
(ref.21 page 9) indicates the value selected.
To view the set parameters at any time, briefly press the PULSE MODE button
(ref.19 page 9) or slightly shift one of the encoders F or D.
To turn off AC mode, hold down the PULSE MODE button (ref.19 page 9) for more
than 2 seconds.
7) In this mode the basic pulse current can be regulated. Pressing the bC button
(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 final welding current A.
8) 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 2 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: after 0.5 seconds of PRE-GAS, the arc is lit by the HF
generator and the welding process starts.
End of welding:
