Pot ON
6 min
The working cycle indicates, in relation to a 10 minute
period of time, the percentage of time in which the
machine is able to weld at the rated current before the
thermal switch intervenes and the corresponding cooling
time. It refers to a 40°C environmental temperature.

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)
