ELECTRICALLY POWERED EQUIPMENT
Faulty or improperly electrified equipment
can cause injury or death. Therefore:
1.
Always have qualified personnel perform the installation,
troubleshooting, and maintenance work. Do not perform
any electrical work unless you are qualified to perform
such work.
2.
Before performing any work inside a power source,
disconnect the power source from the incoming electrical
power using the disconnect switch at the fuse box before
working on the equipment.
3.
Install equipment in accordance with the U.S. National
Electrical Code, all local codes and the manufacture’s
recommendations.
4.
Ground the equipment in accordance with the U.S.
National Electrical Code and the manufacturer’s
recommendations.
CYLINDER HANDLING
Cylinders, if mishandled, can rupture and
violently release gas. Sudden rupture of
cylinder, valve, or relief device can injure or
kill. Therefore:
1.
Use the proper gas for the process and use the proper
pressure reducing regulator designed to operate from
the compressed gas cylinder. Do not use adaptors.
Maintain hoses and fittings in good condition.
2.
Always secure cylinders in an upright position by chain
or strap to suitable hand trucks, undercarriages,
benches, walls, post, or racks. Never secure cylinders to
work tables or fixtures where they may become part of
an electrical circuit.
3.
When not in use, keep cylinder valves closed. Have valve
protection cap in place if regulator is not connected.
Secure and move cylinders by using suitable hand
trucks. Avoid rough handling of cylinders.
4.
Locate cylinders away from heat, sparks, and flames.
Never strike an arc on a cylinder.
5.
For additional information, refer to CGA Standard P-1,
“Precautions for Safe Handling of Compressed Gases in
Cylinders”, which is available from Compressed Gas
Association, 1235 Jefferson Davis Highway, Arlington, VA

HEARING PROTECTION
Prolonged Noise from Capacitor Discharge
welding applications can damage hearing if
levels exceed limits specified by OSHA.
Therefore:
1.
Use Approved ear plugs or ear muffs if noise level is
high.
2.
Warn others nearby about noise hazard.
3.
For additional information, refer to OSHA Safety
Standards 3074.
MOVING PARTS CAN CAUSE INJURY
Electric fan can start at any time without
warning and cause severe injury, therefore:
1.
Always disconnect electrical power prior to service to
prevent the fan from starting unexpectedly.
2.
Keep all doors, panels, covers, and guards closed and
securely in place.
3.
Have only qualified people remove guards or covers for
maintenance and troubleshooting as necessary.
4.
Keep hands, hair, loose clothing, and tools away from
moving parts.
5.
Reinstall panels or guards and close doors when
servicing is finished and before reenergizing welder.
EYE PROTECTION
Flying metal can injure eyes. Welding,
chipping, wire brushing and grinding can
cause sparks and flying metal. As welds cool,
they can throw off slag. Therefore:
1.
Wear approved safety glasses with side shields even
under your welding helmet.
2.
Warn others nearby about flying metal hazard.
EQUIPMENT MAINTENANCE
Faulty or improperly maintained equipment
can cause injury or death. Therefore:
1.
Always have qualified personnel perform the installation,
troubleshooting, and maintenance work. Do not perform
any electrical work unless you are qualified to perform
such work.
2.
Before performing any maintenance work inside a power
source, disconnect the power source from the incoming
electrical power.
3.
Maintain cables, grounding wire, connections, power
cord, and power supply in safe working order. Do not
operate any equipment in faulty condition.
4.
Do not abuse any equipment or accessories. Keep
equipment away from:
•
heat sources such as furnaces
•
wet conditions such as water puddles and inclement
weather
•
oil or grease
•
corrosive atmospheres
5.
Keep all safety devices and cabinet covers in position
and in good repair.
6.
Use equipment only for its intended purpose. Do not
