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 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:
a. Bundle the cable connected to the work piece and the welding cable together.
b. Do not enwind partially or entirely your body with the cable.
c. Do not place yourself between the welding cable and the ground (work piece) cable, if the welding cable is by your
left side, then the ground cable should be by your left side too.
d. The Welding cable and the ground cable are as short as possible.
e. Do not work near to the welding power source.
9 Lift Equipment
: carton or wooden boxes package the welding machines supplied by HUAYUAN.
There is no lifting equipment in its wrapper. Users can move it to the prospective area by a fork-lift
truck, and then open the box.
If having rings, the machine can be transited using rings. While HUAYUAN Welding Machine
Manufacture reminds users, there is possible risk to damage the welding machine. It is better to
push the welding machine moving in use of its rollers unless special situations.
