1-3. Additional Symbols For Installation, Operation, And Maintenance

HOT PARTS can cause severe burns.

DDo not touch hot parts bare handed.

D Allow cooling period before working on torch.

MOVING PARTS can cause injury.

D Keep away from moving parts such as fans.

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

FLYING METAL can injure eyes.

DWear safety glasses with side shields or face shield.

MAGNETIC FIELDS can affect pacemakers.

D Pacemaker wearers keep away.

D Wearers should consult their doctor before go- ing near plasma arc cutting operations.

OVERUSE can cause OVERHEATING.

DAllow cooling period; follow rated duty cycle.

DReduce amperage (thickness) or reduce duty cycle before starting to cut again.

EXPLODING HYDROGEN hazard.

DWhen cutting aluminum underwater or with the water touching the underside of the aluminum, free hydrogen gas may collect under the work- piece.

DSee your cutting engineer and water table instructions for help.

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 unit.

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

FIRE OR EXPLOSION hazard.

D Do not locate 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.

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.

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 elec- tronic equipment perform this installation.

DThe user is responsible for having a qualified electrician promptly correct any interference problem resulting from the installation.

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.

ARC CUTTING can cause interference.

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

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

DLocate cutting operation 100 meters from any sensitive electronic equipment.

DBe sure this cutting power source is installed and grounded according to this manual.

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