SECTION 3 − INTRODUCTION 3-1. Serial Number And Rating Label Location The serial number and rating information for this product is located on the rear panel. Use rating label to determine input power requirements and/or rated output. For future reference, write serial number in space provided on back cover of this manual. 3-2.
3-4. Duty Cycle And Overheating 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 min- utes for unit to cool. Reduce amper- age or voltage, or duty cycle before welding.

Disconnect and lockout/tagout in- put power before connecting input conductors from unit. Always connect green or green/ yellow conductor supply grounding terminal first, and never...
4-4. Electrical Service Guide NOTICE − INCORRECT INPUT POWER can damage this welding power source. Phase to ground voltage shall not exceed +10% of rated input voltage. NOTICE − Actual input voltage should not be 10% less than minimum and/or 10% more than maximum input voltages listed in table. If actual input voltage is outside this range, output may not be be available.
