4-3. Duty Cycle And Overheating
Duty Cycle is percentage of 10
minutes that unit can cut at rated
load without overheating.
If unit overheats, output stops,
temperature status light
illuminates, and cooling fan runs.
Wait fifteen minutes for unit to cool
or temperature light to go off.
Reduce amperage or duty cycle
before cutting or gouging.
Y
Exceeding duty cycle can
damage unit and void
warranty.
