Additional Symbols For Installation, Operation, And Maintenance - Miller SRH-444 Manuel Du Propriétaire

CYLINDERS can explode if damaged.
Shielding gas cylinders contain gas under high
pressure. If damaged, a cylinder can explode. Since
gas cylinders are normally part of the welding process, be sure to
treat them carefully.
Protect compressed gas cylinders from excessive heat,
•
mechanical shocks, physical damage, slag, open flames,
sparks, and arcs.
Install cylinders in an upright position by securing to a stationary
•
support or cylinder rack to prevent falling or tipping.
Keep cylinders away from any welding or other electrical circuits.
•
• Never drape a welding torch over a gas cylinder.
1-3. Additional Symbols For Installation, Operation, And Maintenance
FIRE OR EXPLOSION hazard.
Do not install or place unit on, over, or near
•
combustible surfaces.
Do not install unit near flammables.
•
Do not overload building wiring - be sure power supply system
•
is properly sized, rated, and protected to handle this unit.
FALLING UNIT can cause injury.
Use lifting eye to lift unit only, NOT running gear,
•
gas cylinders, or any other accessories.
• Use equipment of adequate capacity to lift and support unit.
• If using lift forks to move unit, be sure forks are long enough to
extend beyond opposite side of unit.
OVERUSE can cause OVERHEATING.
Allow cooling period; follow rated duty cycle.
•
• Reduce current or reduce duty cycle before starting
to weld again.
Do not block or filter airflow to unit.
•
FLYING SPARKS can cause injury.
• Wear a face shield to protect eyes and face.
Shape tungsten electrode only on grinder with
•
proper guards in a safe location wearing proper
face, hand, and body protection.
Sparks can cause fires—keep flammables away.
•
STATIC (ESD) can damage PC boards.
Put on grounded wrist strap BEFORE handling
•
boards or parts.
Use proper static–proof bags and boxes to store, move, or ship
•
PC boards.
MOVING PARTS can cause injury.
Keep away from moving parts.
•
Keep away from pinch points such as drive rolls.
•
WELDING WIRE can cause injury.
Do not press gun trigger until instructed to do so.
•
Do not point gun toward any part of the body, other
•
people, or any metal when threading welding wire.
Never allow a welding electrode to touch any cylinder.
•
• Never weld on a pressurized cylinder—explosion will result.
Use only correct shielding gas cylinders, regulators, hoses, and
•
fittings designed for the specific application; maintain them and
associated parts in good condition.
Turn face away from valve outlet when opening cylinder valve.
•
Keep protective cap in place over valve except when cylinder is
•
in use or connected for use.
• Use the right equipment, correct procedures, and sufficient
number of persons to lift and move cylinders.
Read and follow instructions on compressed gas cylinders,
•
associated equipment, and Compressed Gas Association
(CGA) publication P–1 listed in Safety Standards.
MOVING PARTS can cause injury.
Keep away from moving parts such as fans.
•
Keep all doors, panels, covers, and guards closed
•
and securely in place.
Have only qualified persons remove doors, panels, covers, or
•
guards for maintenance as necessary.
• Reinstall doors, panels, covers, or guards when maintenance is
finished and before reconnecting input power.
READ INSTRUCTIONS.
• Read Owner's Manual before using or servicing
unit.
Use only genuine replacement parts from the manufacturer.
•
H.F. RADIATION can cause interference.
High–frequency (H.F.) can interfere with radio
•
navigation, safety services, computers, and
communications equipment.
• Have only qualified persons familiar with electronic equipment
perform this installation.
The user is responsible for having a qualified electrician
•
promptly correct any interference problem resulting from the
installation.
If notified by the FCC about interference, stop using the
•
equipment at once.
Have the installation regularly checked and maintained.
•
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.
