Duty Cycle is percentage of 10 min-

utes that unit can weld at rated load

without overheating.

If unit overheats, thermostat(s)

opens, output stops, and cooling

fan runs. Wait fifteen minutes for

unit to cool. Reduce amperage or

duty cycle before welding.

Y Exceeding duty cycle can

damage unit and void war-

ranty.

Volt-ampere curves show minimum

and maximum voltage and amper-

age output capabilities of unit.

Curves of other settings fall be-

tween curves shown.

This volt-ampere curve repre-

sents the dynamic output of the

unit with a static load.
