DUTY CYCLE
The duty cycle of a welding machine is the percentage of
time in a 10 minute cycle at which the welder can operate
the machine at rated welding current.
60% duty cycle:
Weld for 6 minutes
Break for 4 minutes
Excessive extension of the duty cycle may cause the
thermal protection circuit to activate.
THERMAL PROTECTION
The INVERTEC
®
machine is equipped with a thermal
protection device. When the machine has gone into
thermal overload, the output will be turned off and the
thermal indicator light will be turned
