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
Excessive extension of the duty cycle will maybe cause
the thermal protection circuit to activate.
THERMAL PROTECTION
