The symbols shown below are used throughout this manual to call attention to and identify possible hazards. When you see the symbol, watch out, and follow the related instructions to avoid the hazard.

Only qualified persons should test, maintain, and repair this unit.

During servicing, keep everybody, especially children, away.

ELECTRIC SHOCK can kill.

DDo not touch live electrical parts.

DTurn Off welding power source and wire feeder

and disconnect and lockout input power using line disconnect switch, circuit breakers, or by removing plug from re- ceptacle, or stop engine before servicing unless the procedure spe- cifically requires an energized unit.

DInsulate yourself from ground by standing or working on dry insulat- ing mats big enough to prevent contact with the ground.

DDo not leave live unit unattended.

DIf this procedure requires an energized unit, have only personnel familiar with and following standard safety practices do the job.

DWhen testing a live unit, use the one-hand method. Do not put both hands inside unit. Keep one hand free.

DDisconnect input power conductors from deenergized supply line BEFORE moving a welding power source.

SIGNIFICANT DC VOLTAGE exists after removal of input power on inverters.

DTurn Off inverter, disconnect input power, and discharge input capacitors according to instructions in Troubleshooting Section be- fore touching any parts.

STATIC (ESD) can damage PC boards.

DPut on grounded wrist strap BEFORE handling

boards or parts.

D Use proper static-proof bags and boxes to store, move, or ship PC boards.

FIRE OR EXPLOSION hazard.

DDo not place unit on, over, or near combustible surfaces.

DDo not service unit near flammables.

FLYING METAL or DIRT can injure eyes.

DWear safety glasses with side shields or face shield during servicing.

DBe careful not to short metal tools, parts, or wires together during testing and servicing.

HOT PARTS can cause severe burns.

DDo not touch hot parts bare handed.

DAllow cooling period before working on equipment.

DTo handle hot parts, use proper tools and/or wear heavy, insulated welding gloves and clothing to prevent burns.

EXPLODING PARTS can cause injury.

DFailed parts can explode or cause other parts to explode when power is applied to inverters.

DAlways wear a face shield and long sleeves when servicing inverters.

SHOCK HAZARD from testing.

DTurn Off welding power source and wire feeder or stop engine before making or changing me- ter lead connections.

DUse at least one meter lead that has a self- retaining spring clip such as an alligator clip.

DRead instructions for test equipment.
