§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.
