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 equipment's, 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 .
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's.
When engine is hot, it is forbidden to open the airtight cover of the radiator water tank to avoid hurt by the hot
vapor.

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, and 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.

Lifting equipment
: carton or wooden boxes package of the welding machines supplied by
WARPP Engg. There is no lifting equipment in its wrapper. Users can move it to the
prospective area by a fork-lift truck, then open the box.
If there are rings, the machine can be transited by rings. While Our Welding Machine
Manufacture reminds users, there is potential risk to damage the welding machine. So it is better
to push the welding machine by its rollers unless special situations.
Be sure that the appurtenances are all removed off when lifting.
When lifting, make sure that there is no person below the welding machine, and remind people
passing by at any moment.
Do not move the hoist too fast.

Noise
: Our Welding Machine Manufacture reminds users: Noise beyond the limit (over 80 db)
can cause injury to vision, heart and audition depending on oneself. Please consult local
