Control knob
1
All parameters are set by the use of only one
control knob. These parameters include current,
slope-down time, etc.
The digital display shows the value of the parameter
being set. The unit of measurement of the parameter is
shown on the right side of the digital display.
A parameter can be selected by means of the relative
keypad in the relevant section. A bright indication light
indicates the parameter selected. The control knob is then
used for setting a new value.
Welding current
2
A
The key pad can be used to display the welding
current. Adjustable from 10A to 160A.
After the welding process has stopped, the adjusted
current is shown on the display. During welding, however,
the actual welding current is shown. During pulse welding
an average welding current is automatically shown
when shifting between welding current and base current
becomes faster than possible viewing. Press the key for
3 seconds to display the arc voltage. Press again "A" to
display the welding current.

Welding voltage indicator
4
V
The welding voltage indicator is illuminated for
reasons of safety and in order to show if there is voltage
at the electrode holder or TIG torch.
Overheating error indicator
5
The overheating indicator is illuminated if welding is
interrupted due to overheating of the machine.
Mains error indicator
6
The mains error indicator is lit if the mains voltage is
more than 25% lower than the nominal mains voltage.

Pre-flow is the period of time for which gas flows

S
after the torch trigger has been activated and before the
%
HF arc is established, or until the torch is lifted away from
the workpiece in the LIFTIG process. Variable 0-10 sec.
A
Slope-up [s]
8
2
Once the arc has been established, the welding
process enters a slope-up stage during which the welding
current is increased from the value stated in the Start
Amp parameter to the required welding current. The
duration of this slope-up time is variable 0-20 sec. in steps
of 0.1 sec.
12
Slope-down [s]
9
When welding has stopped by activating the
trigger, the machine enters a slope-down stage.
During this phase current is reduced from welding current
to Final Amp. The slope down period is variable 0-20 sec
in steps of 0.1 sec.
Post-flow [s]
10
Post-flow is the period of time for which gas flows
t
2
after the arc is extinguished and is variable 0-20 sec.
11
pulse current is equal to the set current.
It is possible to adjust:
Pulse time
Adjustable from 0.01 to 10 sec. in steps of 0.01 sec.
Pause time
Adjustable from 0.01 to 10 sec. in steps of 0.01 sec.
Base amp
Adjustable from 10 to 90% of the pulse current.
Electrode welding (MMA)
12
Is used for selection of electrode welding. It is not
possible to change welding process during welding.
Torch adjustment /
13
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 10A.

Pulse
Is used for selection of pulse. The
