allow all parts of the Welder to cool thoroughly before service.
1. BEFORE EAcH USE, inspect the general
condition of the welder. Check for:
• loose hardware,
• misalignment or binding of moving parts,
• damaged cord/electrical wiring,
• frayed or damaged cables,
• cracked or broken parts, and
• any other condition that may
affect its safe operation.

Troubleshooting

Be cERTAIN to shut off the Welder, disconnect it from power, and discharge the
