FIRE OR EXPLOSION hazard.

D Do not install or place unit on, over, or near combustible surfaces.

DDo not install unit near flammables.

DDo not overload building wiring – be sure power supply system is properly sized, rated, and protected to handle this unit.

MOVING PARTS can cause injury.

DKeep away from moving parts such as fans.

DKeep all doors, panels, covers, and guards closed and securely in place.

FALLING UNIT can cause injury.

DUse lifting eye to lift unit only, NOT running gear, gas cylinders, or any other accessories.

DUse equipment of adequate capacity to lift and support unit.

DIf using lift forks to move unit, be sure forks are long enough to extend beyond opposite side of unit.

OVERUSE can cause OVERHEATING

DAllow cooling period; follow rated duty cycle.

DReduce current or reduce duty cycle before starting to weld again.

DDo not block or filter airflow to unit.

H.F. RADIATION can cause interference.

DHigh-frequency (H.F.) can interfere with radio navigation, safety services, computers, and communications equipment.

DHave only qualified persons familiar with electronic equipment perform this installation.

DThe user is responsible for having a qualified electrician prompt- ly correct any interference problem resulting from the installa- tion.

DIf notified by the FCC about interference, stop using the equipment at once.

DHave the installation regularly checked and maintained.

DKeep high-frequency source doors and panels tightly shut, keep spark gaps at correct setting, and use grounding and shielding to minimize the possibility of interference.

STATIC (ESD) can damage PC boards.

DPut on grounded wrist strap BEFORE handling boards or parts.

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

MOVING PARTS can cause injury.

DKeep away from moving parts.

DKeep away from pinch points such as drive rolls.

WELDING WIRE can cause injury.

DDo not press gun trigger until instructed to do so.

DDo not point gun toward any part of the body, other people, or any metal when threading welding wire.

ARC WELDING can cause interference.

DElectromagnetic energy can interfere with sensitive electronic equipment such as computers and computer-driven equipment such as robots.

DBe sure all equipment in the welding area is electromagnetically compatible.

DTo reduce possible interference, keep weld cables as short as possible, close together, and down low, such as on the floor.

DLocate welding operation 100 meters from any sensitive elec- tronic equipment.

DBe sure this welding machine is installed and grounded according to this manual.

DIf interference still occurs, the user must take extra measures such as moving the welding machine, using shielded cables, using line filters, or shielding the work area.
