Cautions
Arc and arc rays may harm health
Arc welding can be hazardous. All performing welding workers ought to have health qualification
that provided by authority organization. Protect yourself and others from possible serious injury or
death. Keep children away. Pacemaker wearers should consult with their doctor before operating. Be
sure that all installation, operation, maintenance and repair procedures are performed only by
qualified individuals.
1Electric shock can kill: The electrode and work (or ground) circuits are electrically “hot” when
the welder is on. Do not touch these “hot” parts with your bare skin or wet clothing, Wear dry,
hole-free gloves to insulate hands. Users need to follow the below items to avoid electric shocks:
Insulate yourself from work and ground using dry insulation. Make certain the insulation is large enough to cover
your full area of physical contact with work and ground. Otherwise, use automatic or semiautomatic welding
machines, DC welding machines as possible as you can.
In semiautomatic or automatic wire welding, the electrode,electrode reel, welding head, nozzle or semiautomatic
welding gun are also electrically“hot”.
Always be sure the work cable makes a good electrical connection with the metal being welded. The connection
should be as close as possible to the area being welded.
Ground the work or metal to be welded to a good electrical(earth) ground.
Maintain the electrode holder, work clamp, welding cable and welding machine in good, safe operating
condition. Replace damaged insulation.
Never dip the electrode in water for cooling.
Never simultaneously touch electrically“hot”parts of electrode holders connected to two welders, because
voltage between the two can be the total of the open circuit voltage of both welders.
When working above floor level, please do wear safety belt to avoid falling or losing balance on electric shock.
2Arc rays can burn: Use a shield with the proper filter and cover plates to protect your eyes from
sparks and the rays of the arc when welding or observing open arc welding. Headshield and
filter lens should conform to nation standards.
Use suitable clothing made from durable flame-resistant material to protect your skin and that of your helpers
from the arc rays.
Protect other nearby personnel with suitable, non-flammable screening and/or warn them not to watch the arc
nor expose themselves to the arc rays or to hot spatter or metal.
3Fumes and Gases can be dangerous: Welding may produce fumes and gases hazardous to
health. Avoid breathing these fumes and gases. While working in limited room, use enough
ventilation and/or exhaust to keep fumes and gases away from the breathing zone, or use the

RSN-1600/2500/3150HD OPERATOR’S MANUAL
3
respirator.
Shielding gases used for arc welding can displace air and cause injury or death. Always use enough
ventilation,especially in confined areas to insure breathing air is safe.
Do not weld in locations near chlorinated hydrocarbon vapors coming from degreasing, cleaning or spraying
operations.The heat and rays of the arc can react with solvent vapors to form phosgene, a highly toxic gas, and
other irritating products.
Read and understand the manufacturer’s instructions for this equipment and the consumables to be used,
including the material safety data sheet (MSDS) and follow your employer’s safety practices. Make sure they are
asepsis and innocuity.
4Spatter: 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.
5Cylinder 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.
6Power: (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.
7Power:(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 .
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
maintenances.
When engine is hot, it is forbidden to open the airtight cover of the radiator water tank to avoid hurt by the hot
vapor.
8Electromagnetic: 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. D e. Do not work near to the welding power source.
9Lifting 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, then open the box.
If there are rings, the machine can be transited by rings. While Huayuan 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.
10 Noise: Huayuan 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
medical institution. Use the equipment after doctor’s permission would help to keep healthy.
