Duty Cycle is percentage of 10 m in -
utes that unit can weld at rated load
without overheating.
Exceeding duty cycle can
damage unit and void
warranty.
60% Duty Cycle At 325 Amperes
100% Duty Cycle At 250 Amperes

3-4. Volt-Ampere Curves

SB-183 882
The volt-ampere curves show the
minimum and maximum voltage
and amperage output capabilities of
the welding generator. Curves of
other settings fall between the
curves shown.
