§4.4 Operation Notices
▲ Read §1 carefully before attempting to use this equipment.
▲ NEMA power cord plug must be inserted directly into GROUNDED outlet by others.
▲ Insure that the input LINE circuit is rated at nameplate voltage with 20-amp (Min.) breaker.
▲ Ensure good ventilation of the machine to improve duty-cycle ratio.
▲ Make certain welding area is free of all flammable or combustible materials.
▲ Turn off the power switch when the operation finished for economize energy sources.
▲When output shuts off and ALERT lamp illuminates, do not restart it until problem is resolved.
Otherwise, the range of problem will be extended and machine may be damaged.
▲In case of problems, contact your local dealer or authorized repair center.
