Duty Cycle And Overheating Duty Cycle is percentage of 10 minutes 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. 60% Duty Cycle Overheating 0 15 A or V OR Minutes Reduce Duty Cycle Ref. 216 568-A Notes OM-2251 Page 13 SECTION 4 . INSTALLATION 4-1.

Installation must meet all National and Local Codes . have only qualified persons make this installation. ! Disconnect and lockout/tagout input power before connecting input conductors from unit. ! Always connect green or green/yellow conductor to supply grounding terminal first, and never to a line terminal. The Auto-Line circuitry in this unit automatically adapts the power source to the primary voltage being applied. Check input voltage available at site. This unit can be connected to any input power between 208 and 575 VAC without removing cover to relink the power source. 1 Black And White Input Conductor (L1 And L2) 2 Red Input Conductor 3 Green Or Green/Yellow Grounding Conductor 4 Insulation Sleeving 5 Electrical Tape Insulate and isolate red conductor as shown. 6 Input Power Cord. 7 Disconnect Device (switch shown in the OFF position) 8 Disconnect Device Grounding Terminal 9 Disconnect Device Line Terminals Connect green or green/yellow grounding conductor to disconnect device grounding terminal first. Connect input conductors L1 and L2 to disconnect device line terminals. 10 Overcurrent Protection Select type and size of overcurrent protection using Section 4-5 (fused disconnect switch shown).
