Digital display
The control panel is equipped with a
green LED display showing the
welding current. During standby the pre-set welding
current is displayed, while the mean current is shown
during welding.
Disconnection error
A yellow LED indicates that the machine is
overheated due to overloading. When the situation is
back to normal, the machine will reconnect auto-
matically. Therefore, welding cables are to be placed
so as to avoid the risk of unintended establishment
of the arc when the machine reconnects.
Welding voltage
For safety reasons the welding voltage
LED lights if the electrode or the torch is under
voltage.
Welding current
Welding current is adjusted by means of
this button. The current is adjustable from
10 A to 160A.
Function switch
This switch is used to choose
between
between two-stroke and four-stroke in
TIG welding, and to choose ignition
method in TIG welding.
This symbol means MMA welding.
This symbol means TIG welding.

welding,
Two-stroke:
This symbol means contact-free striking.
The arc is established in the following way:
1) The torch is placed so that the Tungsten elec-
trode is quite close to the welding spot (1 or 2
mm).
2) The torch trigger is activated and must be kept
pressed down. The high voltage generator of the
machine will produce a voltage impulse that
ignites the arc. The welding process has started.
The welding process will stop when the torch
trigger is deactivated. The arc will extinguish after
the period of slope-down time.
Four-stroke:
This symbol means contact-free striking.
The arc is established in the following way:
1) The torch is placed so that the Tungsten elec-
trode is quite close to the welding spot (1 or 2
mm).
2) The torch trigger is activated and deactivated,
and the high voltage generator of the machine
will produce a voltage impulse that ignites the
arc. In order to stop the welding process the
trigger must be activated again after which the
slope-down period begins. The arc will extinguish
after the period of slope-down time, and the
trigger is deactivated. The welding current is
immediately stopped and the arc extinguished if
the torch trigger is released before the slope-
down period is finished.
Two-stroke LIFTIG:
This symbol means LIFTIG ignition. The
arc is established in the following way:
1) The torch is placed so that the Tungsten elec-
trode has contact with the welding spot.
2) The torch trigger is activated and must be kept
pressed down.
3) The arc is established by lifting the torch, and the
welding process has started. In order to stop the
welding process, the torch trigger is deactivated.
The arc will extinguish after the period of slope-
down time.
