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, cuff-less 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, maintenance 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 equipment, 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.
Do not put your hand close to fans and do not move the brake handle while operating.
Please remove the connection between the engine and the welding equipment to avoid sudden starting during
maintenance.
●
When engine is hot, it is forbidden to open the airtight cover of the radiator water tank to avoid hurt by the hot vapor.
8, Electromagnetic
: Welding current going though any area can generate electromagnetic, as well as the
welding equipment itself.
Electromagnetic would affect cardiac pacemaker, the cardiac pacemaker users should consult one’s doctor
first.
The effect of electromagnetic to one’s health is not confirmed, so it might have some negative effect to one’s health.
Welders may use following method to reduce the hazardous of electromagnetic:
