– 150A
U
r
= Reduced open circuit voltage
Is the voltage (excluded any stabilization voltage or arc ignition) found between the output outlets
when the welding machine is not welding. This is the voltage a welder can be exposed to between
electrode holder and work piece.
U
2
= Arc voltage
Voltage present between the output outlets when welding is being carried out, in relation to a
particular set current. The relation, for the various welding modes is the following:
MMA→ U2=(20+0,04*I2)
TIG → U2=(10+0,04*I2)
Primary connection
U

= Effective input voltage 230V
I
1max
= Maximum value of input current at the corresponding duty cycle.
I
1eff
= Effective value of input current at the corresponding duty cycle.
Cooling
COOLING AF= Forced air cooling (with a fan).
