4-10. Static Output Characteristics
The static (output) characteristics of the welding power source can be described as flat during the GMAW process and drooping during the SMAW
and GTAW processes. Static characteristics are also affected by control settings (including software), electrode, shielding gas, weldment material,
and other factors. Contact the factory for specific information on the static characteristics of the welding power source.

Reduce Duty Cycle
Duty Cycle is percentage of 10 min-
utes that unit can weld at rated load
without overheating.
If unit overheats, output stops, a Help
message is displayed and cooling fan
runs. Wait fifteen minutes for unit to
cool. Reduce amperage or voltage, or
duty cycle before welding.
.
Single Phase Operation: The
unit is supplied with a 8 AWG
power cord. The rated output
with 8 AWG is 300 amps, 32
volts at 40% duty cycle. To
achieve 60% duty cycle change
cord to 6 AWG.
NOTICE − Exceeding duty cycle can
damage unit and void warranty.
