3.2 Duty Cycle
Duty cycle is the percentage of ten minutes that the unit can weld at selected current
without overheating.
If the unit was used at 450A (Maximum Current) then the unit could weld
continuously, that is no time is needed in order to let the unit cool.
3.3 Selecting Location
The air is blown from the rear of the unit through the heatsink and out the front of the
unit, therefore adequate thought needs to be considered about the location of the
unit.
The unit should be spaced at least 15cm away from a wall at the rear of the
machine, this will allow adequate airflow into the unit.
