Spatter
: Welding or cutting spatter can cause fire or explosion.
Remove fire hazards from the welding area. If this is not possible, cover them to prevent the
welding sparks from starting a fire. Remember that welding sparks and hot materials from
welding can easily go through small cracks and openings to adjacent areas. Avoid welding near hydraulic lines.
Have a fire extinguisher readily available.
Where compressed gases are to be used in the field, special precautions should be used to prevent explosion.
When not welding, make certain that no electriferous 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 innocuity.
Do not heat, cut or weld tanks, drums or containers until the proper steps have been taken to insure that such
procedures will not cause flammable or toxic vapors from substances inside. They can cause an explosion even
though they have been“cleaned”.
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.

Cylinder may explode if damaged.
Make sure that the gas in the storage cylinder is qualified for welding, and the decompression
flowmeter, the adapter and the pipe are all in good condition.
Always keep cylinders in an upright position securely chained to an undercarriage or fixed support.
Be sure to put the cylinder in the working space with no crash or shake, and far from welding area.
Never allow the electrode, electrode holder or any other electrically“hot”parts to touch a cylinder.
Keep your head and face away from the cylinder valve outlet when opening the cylinder valve.
Valve protection caps should always be in place and hand tight except when the cylinder is in use or connected
for use.

Power
: (For electrically powered welding and cutting equipment) Turn off input power before
installation, maintenance and repair to avoid accidents.
Huanyuan 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.

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 some parts of the equipment have to be dismantled during maintenance, but you still have to keep
the strongest safety awareness .
