remote control – 7-poled plug
The regulation of welding current is made by means of
the torch potentiometer (optional). The maximum current
reachable is the level previously adjusted on the front
panel. The minimum current is 5A.
Trigger mode
16
Selection of trigger mode. Four-times trigger mode
is active when the LED is illuminated, and two-times trigger
mode is active when the LED is turned off. It is not possible
to change trigger method during the welding process.
Two-times
The welding process begins by pressing the torch trigger.
Welding continues until the trigger is released again which
effects the slope-down period.
Four-times
The welding process begins by pressing the torch trigger.
If the torch trigger is released during the slope-up period
welding continues with the adjusted welding current. In
order to stop the welding process the trigger must be
pressed again for more than 0.5s after which the slope-
down period begins. The slope-down period can be
stopped by releasing the trigger. Thereafter the post-flow
starts.
Ignition methods
17
It is possible to choose between 2 different methods
of ignition for TIG welding: High-Frequency (HF) and LIFTIG
ignition. The ignition method cannot be changed during
welding. The LIFTIG ignition is active when the indicator is
illuminated. The HF is automatically active when the LED is
switched off.
HF-ignition
In HF-TIG ignition the TIG arc is ignited without contact.
A high-frequency (HF) impulse initiates the arc when the
torch trigger is activated.
The HF will not arise and the machine will stop if the
electrode is in contact with the workpiece. Detach the
electrode and start again.
LIFTIG-ignition
In LIFTIG ignition the TIG arc is ignited after making
contact between the workpiece and the tungsten
electrode, after which the trigger is activated and the arc is
established by lifting the electrode from the workpiece.
Power reduction

reduces the maximum welding current both in
MMA (to 120A) and TIG (to 150A) when its value is lower
than 230V-10% (195V), permitting reduced operations in
case of low supply.
Only after the mains has recovered normal levels, it will be
possible to increase the current up to maximum by rotating
the encoder.
Anti-freeze
This machine is provided with an anti-freeze control.
The anti-freeze-control reduces the current when the
electrodes stick to the weld piece. This makes it easier to
break off the electrode and welding can continue.
Reset
It is possible to reset the welding machine to its factory
settings:
• MMA current 80A
• TIG current 80A
• Pre-flow 0.2 sec
• Post-flow 6.0 sec
• No slope-down
• Base amp 40%
• Pause time = Pulse time = 0.1 sec
• AC-T-Balance (AC) 65%
• Electrode Pre-heating (AC) 5
To activate reset, switch off the machine and wait until
the display is extinguished. Press the "
