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
：
(For electrically powered welding and cutting equipment) Turn off input power before
installation, maintenances and repair, so that avoid accident.
HUAYUAN welding equipment is Ι class safeguard equipment; please install the equipment in accordance with
the manufacturer’s recommendations by specific persons.
Ground the equipment perfectly in accordance with the manufacturer’s recommendations.
7 Power
：
(For engine driven welding and cutting equipment)
Work in ventilated place or outdoors.
Do not add fuel near to fire or during engine starting or welding. When not working, add fuel after engine is cooling
down; otherwise, the evaporation of hot fuel would result in dangers. Do not splash fuel out of the fuel tank, and do
not start the engine until complete evaporation of the outside fuel.
Make sure that all the safeguard equipments, machine cover and devices are all in a good condition. Be sure
that arms, clothes and all the tools do not touch all the moving and rotating components including V belt, gear and
fan etc.
Sometimes having to dismantle some parts of the device during maintenance, but must keep safety awareness
strongly every time.
