SECTION 4 − SPECIFICATIONS AND INSTALLATION

4-1. Serial Number And Rating Label Location

The serial number and rating information is located on the bottom of the machine. Use the rating labels to determine input power requirements and/or
rated output. CE model rating labels will also display the following symbols: CE, CCC, WEEE, and IEC 60974-1. For future reference, write serial
number in space provided on back cover of this manual.

Duty Cycle is percentage of 10 min-
utes that unit can weld at rated load
without overheating.
If unit overheats, output stops, the
Overtemperature Light comes On,
and the cooling fan runs. Wait fif-
teen minutes for unit to cool. Re-
duce amperage or duty cycle be-
fore starting to weld again.
NOTICE − Exceeding duty cycle
can damage unit and void warranty.
