welding, which ensures a cleaner weld starting point
HOT -START = This feature enables igniting problematic electrodes
through automatic increase of the voltage at startup. After ignition the
unit automatically returns to the preset voltage.
HOTSTART
ANTI-STICK = This feature prevents overheating of the electrode, by
reducing the current automatically.
GAS PROTECTION = For TIG welding an inert gas
is necessary (e.g. argon).

POWER-FANS = the high quality fans ensure optimal reduction of the
heat generated during works performed with this high-end device

POST TIME = gas flow variable at second intervals. This regulation is
important for the cooling of the melted weld metal after the welding
process and to protect against oxidation..

ERROR INDICATOR = The indicator lights in the following two situa-
tions:
a) If the machine has malfunctioned and can not be operated.
b) If the cutting device has exceeded the standard working time the
protection mode is initiated and the machine will stop functioning.
This means that the machine is now being cooled in order to be able
to restore temperature control again after the device has overheated.
Therefore the machine is stopped. During this process, the red
warning light on the front panel lights up. In this case it is not necessary
to remove the power plug from the socket. The ventilation system
may be left on in order to enhance the cooling of the machine. When
the red light goes dark, this means that the temperature is now down
to the normal level and the unit can be put back into operation.

MMA-connection = Manual arc welding, briefly called MMA, is one
of the oldest electric welding procedures used for metallic materials,
which is still used today. An electronic arc, formed between an
electrode melted as a filler metal and the workpiece, is used as a heat
source for welding.

TIG-/PLASMA TOR CH CONNECTION
Unlike the metal-inert gas MIG/MAG , in TIG welding the arc burns
between a non-consumable tungsten electrode and the base material. In
order to protect the tungsten electrode and the weld pool it is necessa-
ry to use inert gases, such as argon or helium or gas mixtures with non-
