Duty Cycle is percentage of 10 min-
utes that unit can cut at rated load
without overheating.
If unit overheats, thermostat(s)
opens, output stops, Temperature
trouble light goes On, 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
warranty.
