When you turn the main switch to position I, signal light is lit and the unit is
ready for welding. Signal light is always on, when the unit is connected to the
mains and the main switch is in position I.

when the circuit is activated and the unit is in working order.
Welding process selector, MMa
Switch is used for selecting either MMA or TIG welding, depending on
welding target.
VRD: When you have switched the unit to TIG welding, VRD is constantly
active, thus reducing terminal voltage to 30 V. This facilitates arc cut-off when
you stop welding.
regulating welding current
Welding current rate is regulated steplessly with an adjusting potentiometer.
signal light for overheating
A yellow signal light of overheating is lit, when thermostat has tripped due
to the unit's overheating. Fan will cool the unit and after the signal light goes
