§3.2 Duty cycle and Over-temp
The rated duty cycle is defined as the proportion of the time that a machine can work continuously
over a 10 minute cycle when set at 100% of rated output welding current in 40C (104F) ambient
environment.
When the transformer reaches an over-heat condition, the heat sensor inside it will open and will
output an instruction to circuit board to cut AC relay and the output welding current while illuminating
the over-heat pilot lamp in the front panel. At this time, all welding operations should cease for 15
minutes allowing the cooling fan to reduce the temperature. The unit will auto-reset when correct
temperature has been achieved and pilot light will go out. If the machine reached the over-temp
capacity again, the welding output current or the arc cycle should be reduced.
