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.

WELDING

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.

5-3. Additional Installation, Operation, And Maintenance Hazards

FIRE OR EXPLOSION can result from

placing

combustible surfaces.

1. Do not locate unit on, over, or near combustible

surfaces.

2. Do not install unit near flammables.

FALLING

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.

1. Pacemaker wearers keep away.

2. Wearers should consult their doctor before going

near arc welding, gouging, or spot welding

operations.

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.

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.

MOVING PARTS can cause injury.

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

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.
