206 (TIG DC) Easy joining
Allows striking of the arc in pulsed current and timing of
the function before the automatic reinstatement of the
pre-set welding conditions.
Allows greater speed and accuracy during tack welding
operations on the parts.
Parameter setting: seconds (s).
Minimum 0.1s, Maximum 25.0s, Default off
312 Arc detachment voltage
Allows you to set the voltage value at which the electric
arc switch-off is forced.
It permits improved management of the various operat-
ing conditions that occur. In the spot welding phase,
for example, a low arc detachment voltage reduces
re-striking of the arc when moving the electrode away
from the piece, reducing spatter, burning and oxidisa-
tion of the piece.
Never set an arc detachment voltage higher than
the no-load voltage of the power source.
Minimum 0.0V, Maximum 99.9V, Default 45V
500 Allows access to the higher set-up levels:
USER: user
SERV: service
vaBW: vaBW
601 (U/D) Adjustment step
Permits adjustment of the variation step on the up-
down keys.
Minimum Off, Maximum MAX, Default 1
602 CH1 External parameter
Allows the management of external parameter 1 (mini-
mum value).
603 CH1 External parameter
Allows the management of external parameter 1 (maxi-
mum value).
606 U/D torch
Allows the management of the external parameter (U/D).
0=Off, 1=A
750 Measurements
Permits selection of the type of measurement to be
shown on the display 4.
A Real current
U Real voltage
751 Current reading
Allow the real value of the welding current to be dis-
played.
Allows the welding current display method to be set
(consult the "Interface personalisation" section).
752 Voltage reading
Allows the real value of the welding voltage to be dis-
played.
Allows the welding voltage display method to be set
(consult the "Interface personalisation" section).

3.2.3 Lock/unlock
Allows all the settings to be locked from the control panel with
a security password.
Enter set-up by pressing the encoder key for at least 5 seconds.
Select the required parameter (551) by rotating the encoder
until it is displayed within the central quadrant.
Activate the regulation of the selected parameter by pressing the
encoder button.
Set a numerical code (password) by rotating the encoder.
Confirm the change made by pressing the encoder button.
3.3 Rear panel
1 Power supply cable
Connects the system to the mains.
2 Gas fitting
3 Signal cable (CAN-BUS) input (RC)
4 Off/On switch
Turns on the electric power to the welder.
It has two positions, "O" off, and "I" on.
3.4 Sockets panel
1 Negative power socket
For connection of earth cable in electrode welding or of
torch in TIG.
2 Positive power socket
For connection of electrode torch in MMA or earth
cable in TIG.
