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.
1. Protect compressed gas cylinders from excessive heat,
mechanical shocks, slag, open flames, sparks, and arcs.
2. Install cylinders in an upright position by securing to a stationary
support or cylinder rack to prevent falling or tipping.
3. Keep cylinders away from any welding or other electrical
circuits.
4. Never drape a welding torch over a gas cylinder.
5. Never allow a welding electrode to touch any cylinder.
6. Never weld on a pressurized cylinder – explosion will result.
7. Use only correct shielding gas cylinders, regulators, hoses, and
fittings designed for the specific application; maintain them and
associated parts in good condition.
8. Turn face away from valve outlet when opening cylinder valve.
9. Keep protective cap in place over valve except when cylinder is
in use or connected for use.
10. Read and follow instructions on compressed gas cylinders,
associated equipment, and CGA publication P-1 listed in Safety
Standards.
WELDING can cause fire or
explosion.
Welding on closed containers, such as tanks,
drums, or pipes, can cause them to blow up. Sparks
can fly off from the welding arc. The flying sparks,
hot workpiece, and hot equipment can cause fires
and burns. Accidental contact of electrode to metal
objects can cause sparks, explosion, overheating,
or fire. Check and be sure the area is safe before
doing any welding.
1. Protect yourself and others from flying sparks and hot metal.
2. Do not weld where flying sparks can strike flammable material.
3. Remove all flammables within 35 ft (10.7 m) of the welding arc. If
this is not possible, tightly cover them with approved covers.
4. Be alert that welding sparks and hot materials from welding can
easily go through small cracks and openings to adjacent areas.
5. Watch for fire, and keep a fire extinguisher nearby.
6. Be aware that welding on a ceiling, floor, bulkhead, or partition
can cause fire on the hidden side.
7. Do not weld on closed containers such as tanks, drums, or
pipes, unless they are properly prepared according to AWS F4.1
(see Safety Standards).
8. Connect work cable to the work as close to the welding area as
practical to prevent welding current from traveling long, possibly
unknown paths and causing electric shock and fire hazards.
9. Do not use welder to thaw frozen pipes.
10. Remove stick electrode from holder or cut off welding wire at
contact tip when not in use.
11. Wear oil-free protective garments such as leather gloves, heavy
shirt, cuffless trousers, high shoes, and a cap.
12. Remove any combustibles, such as a butane lighter or matches,
from your person before doing any welding.
1-3. Additional Installation, Operation, And Maintenance Hazards
FIRE OR EXPLOSION can result from
placing unit on, over, or near
combustible surfaces.
1. Do not locate unit on, over, or near combustible
surfaces.
2. Do not install unit near flammables.
FALLING EQUIPMENT can cause
serious personal injury and equipment
damage.
1. Use lifting eye to lift unit only, NOT running gear,
gas cylinders, or any other accessories.
2. Use equipment of adequate capacity to lift unit.
3. If using lift forks to move unit, be sure forks are
long enough to extend beyond opposite side of
unit.
HOT PARTS can cause severe burns.
1. Do not touch hot parts bare handed.
2. Allow cooling period before working on gun or
torch.
MOVING PARTS can cause injury.
1. Keep away from moving parts such as fans.
2. Keep all doors, panels, covers, and guards closed
and securely in place.
MAGNETIC FIELDS FROM HIGH
CURRENTS can affect pacemaker
operation.
1. Pacemaker wearers keep away.
2. Wearers should consult their doctor before going
near arc welding, gouging, or spot welding
operations.
MOVING PARTS can cause injury.
1. Keep away from moving parts.
2. Keep away from pinch points such as drive rolls.
FLYING PIECES OF METAL or DIRT can
injure eyes.
1. Wear safety glasses with side shields or face
shield.
WELDING WIRE can cause puncture
wounds.
1. Do not press gun trigger until instructed to do so.
2. Do not point gun toward any part of the body, other
people, or any metal when threading welding wire.
HIGH-FREQUENCY RADIATION can
interfere with radio navigation, safety
services, computers, and
communications equipment.
1. Have only qualified persons familiar with
electronic equipment perform this installation.
2. The user is responsible for having a qualified
electrician promptly correct any interference
problem resulting from the installation.
3. If notified by the FCC about interference, stop
using the equipment at once.
4. Have the installation regularly checked and
maintained.
5. 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.
