4 Spatter
: Spatter can cause fire or explosion.
Remove fire hazards from the welding area. Remember that spatter from welding
can easily go through small cracks and touch fire hazards. Protect all kinds of lines
going though welding area, including hydraulic lines in the wild.
Where compressed gases are to be used in the field, special precautions should be used to prevent
explosion.
When welding stops, make certain that no live part is touching the work piece or the work stage.
Accidental contact can create a fire hazard.
Do not weld containers or lines, which are not proved to be innocuous.
It is very dangerous to heat, cut or weld tanks or containers at entry holes. Does not start work until
the proper steps have been taken to insure that there is no flammable or toxic gas.
Spatter might cause burn. Wear leather gloves, heavy shirt, cuffless trousers, high shoes and a cap
over your hair to prevent from burning by spatter. Wear the ear shield when performing sideways
or face up welding. Always wear safety glasses with side shields when being in a welding area.
The welding cables should be as close to the welding area as possible, and the short, the better.
Avoid welding cables going through the building framework, lifting chains, AC or DC cables of
other welding machines and appliances. The welding current is strong enough to damage them
while having short circuit with them.
5 Cylinder
: Damage of it might cause explosion.
Make sure that the gas in the storage cylinder is qualified for welding, and the
decompression flow-meter, the adapter and the pipe are all in good condition.
Make sure that the installation of cylinder is by the wall and bundled tightly by a chain.
Be sure to put the cylinder in the working space with no crash or shake, and far from welding area.
It is forbidden to touch cylinder with the welding clamp or the work cables.
Avoid facing the cylinder while installing the decompression flow-meter or the gasometer.
When not working, please tighten the valve.
6 Power
