2. ARC WELDING SAFETY PRECAUTIONS (continued)
CYLINDER can explode if damaged.
A shielding gas cylinder contains high-pressure gas. If damaged, a cylinder can explode.
Since gas cylinders are normally part of the welding process, be sure to handle them carefully.
1. Use only correct shielding gas cylinders, gas regulator, hoses, and fittings designed for
the specific application; maintain them in good condition.
2. Protect compressed gas cylinders from excessive heat, mechanical shock, and arcs.
3. Keep the cylinder upright and securely chained to a stationary support or a rack to
prevent falling or tipping.
4. Keep cylinders away from any welding or other electrical circuit.
5. Never touch cylinder with welding electrode.
6. Read and follow instructions on compressed gas cylinders, associated equipment, and
the CGA publication P-1 listed in PRINCIPAL SAFETY STANDARDS.
7. Turn face away from the valve outlet when opening cylinder valve.
8. Keep protective caps in place over valve except when a gas cylinder is in use or
connected for use.
9. Do not disassemble or repair the gas regulator except if you are authorized by the
manufacturer.
Rotating parts may cause injuries. Be sure to observe the
following.
If hands, fingers, hair or clothes are put near the fan’s rotating parts or wire feeder’s feed roll,
injuries may occur.
1.
Do not use this equipment if the case and the cover are removed.
2.
When the case is removed for maintenance/inspection and repair, certified or experienced
operators must perform the work. Erect a fence, etc. around this equipment to keep others
away from it.
3.
Do not put hands, fingers, hair or clothes near the rotating fans or wire feed roll.
ARC WELDING work areas are potentially hazardous.
FALLING or MOVING machines can cause serious injury.
1. When hanging the welding power source by a crane, do not use the carrying handle.
2. Put the welding power source and wire feeder solidly on a flat surface.
3. Do not pull the welding power source across a floor laid with cables and hoses.
4. Do not put wire feeders on the welding power source.
5. Do not put the welding power source or wire feeder where they will pit or fall.
WELDING WIRE can cause puncture wounds.
1. Do not press the gun trigger until instructed to do so.
2. Do not point the gun toward any part of the body, other people, or any metal when threading
welding wire.
