1-3. Additional Symbols For Installation, Operation, And Maintenance
HOT PARTS can cause severe burns.
D Do 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.
D Wear 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.
D Allow cooling period; follow rated duty cycle.
D Reduce amperage (thickness) or reduce duty
cycle before starting to cut again.
EXPLODING HYDROGEN hazard.
D When cutting aluminum underwater or with the
water touching the underside of the aluminum,
free hydrogen gas may collect under the work-
piece.
D See your cutting engineer and water table instructions for help.
FALLING UNIT can cause injury.
D Use lifting eye to lift unit only, NOT running
gear, gas cylinders, or any other accessories.
D Use equipment of adequate capacity to lift unit.
D If 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.
D Do not install unit near flammables.
D Do 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.
D Put 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.
D High frequency (H.F.) can interfere with radio
navigation, safety services, computers, and
communications equipment.
D Have only qualified persons familiar with elec-
tronic equipment perform this installation.
D The user is responsible for having a qualified electrician promptly
correct any interference problem resulting from the installation.
D If notified by the FCC about interference, stop using the equipment
at once.
D Have the installation regularly checked and maintained.
D Keep 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.
D Electromagnetic energy can interfere with
sensitive electronic equipment such as
computers and computer-driven equipment
such as robots.
D To reduce possible interference, keep cables as short as possible,
close together, and down low, such as on the floor.
D Locate cutting operation 100 meters from any sensitive electronic
equipment.
D Be sure this cutting power source is installed and grounded
according to this manual.
D If 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.
