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 cause the
thermal protection circuit to activate.
THERMAL PROTECTION
TM
The INVERTEC machine is equipped with a thermal
overheating protection device. When the machine
detects overheating, the output will be turned "OFF"
and the Thermal Indicator Light will be turned "ON".
When the machine has been cooled to a safe
temperature, the Thermal Indicator Light will go out and
the machine may resume normal operation.
Note: For safety reasons the machine's welding output
will not come on after a thermal shutdown until the
output is disabled and re-enabled.
