3-3. Duty Cycle And Overheating
Duty Cycle is percentage of 10
minutes that unit can weld at rated
load without overheating.
If unit overheats, thermostat(s)
opens, over temperature LED
lights, output stops, and cooling fan
runs. Wait fifteen minutes for unit to
cool, the therostat will automatically
reset. Reduce amperage or duty
cycle before welding.
NOTICE
−
Exceeding duty cycle
can damage unit or gun and void
warranty.
