What should I do if the unit overheats and stops outputting power?
If the unit overheats, output stops, a 'HELP' message is displayed, and the cooling fan runs. Wait fifteen minutes for the unit to cool down before welding again. Before resuming, reduce the welding current, voltage, or duty cycle to prevent recurrence. (Page 11)
