Arc and arc rays can hurt.
All performing welding workers ought to have health qualification from the authority organization to prevent you and
others from arc radiation and burn. It should be prevented for children to enter into dangerous area as well.
Carefully read the following important items and the welder safety bye-law from the authority organization. Be sure that
qualified professionals perform all installation, maintenance and repair procedures.
1 Electric shock: The welding circuits are not insulated when welding. If you touch the two output
electrodes of the machine with your bare skin at the same time, it will lead to electric shock,
sometimes even fatal dangers. Users need to follow the items below to avoid electric shocks:
If possible, lay some insulating materials, which are dry and large enough, in your working field.
Otherwise, use the automatic or semiautomatic welding machine, DC welding machine as possible as you can.
Components in the automatic and semiautomatic welding machine such as the welding wire reel, feed wheel,
contact tip and welding head are all electric components. .
Always be sure the machine has been connected perfectly to the work piece with the work cables and should be as
close as possible to the working area.
The work piece should be grounded perfectly.
Make sure that the insulating material of the electrode holder, the grounding clamp, the welding cable and the
welding head are not affected by damp, mildewed or spoil, and be replaced momentarily.
Never dip the electrode in water for cooling.
Never touch electric components of two welding machines at the same time, because this voltage is supposed to
be two times of welding voltage while the grounding mode is not clear.
While working high above the ground or other places having the risk of falling, please be sure to wear safety belt to
avoid losing balance caused by electric shock.
2 Arc: Use an arc welding mask to protect your eyes and skin from sparks and the rays of the arc, pay
special attention to the filter glass, which must be conformable to the national standard.
Use clothing made from durable flame-resistant material or sailcloth to protect your skin from
hurting by the arc rays.
Remind other nearby personnel before working lest arc rays hurt them by accident.
3 Fumes and Gases: 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 respirator. Do not weld at the same time when
using of degrease, cleaning or spraying operations. The heat and rays of the arc can react with these
gases to form phosgene, a highly toxic gas,
Some protective gases used in welding might displace the oxygen in the air, and can lead to hurt or even death.
Read and understand the manufacturer’s instructions for this equipment, and validate the health certification of
consumptive materials, make sure they are innocuous.
4 Spatter: Spatter can cause fire or explosion.
Remove fire hazards from the welding area. Remember that spatter from welding can easily go
through small cracks and touch fire hazards. Protect all kinds of lines going though welding area,
including hydraulic lines in the wild.
Where compressed gases are to be used in the field, special precautions should be used to prevent explosion.
When welding stops, make certain that no live 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 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:
a. Bundle the cable connected to the work piece and the welding cable together.
b. Do not en-wind 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.
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.

1CBM air
⑵Temperature: grade 4, humidity pressure must be less or equal to 3℃
⑶Oil: grade 2, the density of the oil in air can’t be more than 0.1mg/m3
4. Requirement of torch coolant
Before transportation, all coolant in the machine has been take out, customer need full fill proper coolant before
operation
Warnings:
Warning! The cooling liquid is irritant to skin and eyes, if wrongly eat or drink, it hurts even kills.
If skin and eyes contact with the coolant liquid, please wash immediately with lot of clean water, then go to the hospital
to ask for help.
Notice! Do not use the anti-freezing solution as the coolant, it hurt the torch! To protect the
bump and torch cooling system, please do use the special coolant liquid.
The working temperature of the coolant liquid of this system is -12℃~40℃
The coolant box is empty when delivery out. Before fulling the coolant box, please check which coolant is suitable for
your environment. The standard coolant liquid of this cutting system is composed by 69.8% water, 30% propylene glycol
and 0.2% benzotriazole.
If working temperature is not in the range of -12℃~40℃, please check the suggestion of self-control mixed
coolant liquid below. To make the self-control mixed coolant liquid, please do use pure water in case of hurting the
cooling system.
The self-control mixed coolant liquid that used in low temperature (Under -12℃)
Notice! When the working temperature is lower than -12℃, the percentage composition of propylene glycol must
be improved. Or the frozen coolant may break the torch and pipes. Please reference to the below table for suitable
percentage composition of propylene glycol. However, the percentage composition of propylene glycol can not higher
than 50%.

8
The self-control mixed coolant liquid that used in high temperature (over 38℃)
The treated water can only be used as coolant when the environment temperature is higher than 0℃. The treated
water cool the system very well when used in a warm environment.
The treated water is a mixed water with water(which meet the below purity standard) and benzotriazole with
percentage of 300:1.
Water purity
It’s vital to control the CaCO3 content with a low level, to reduce the hurt to the cutting torch.
If use self-control mixed coolant liquid, please make sure the water always accord with the below table standard.
Both the lowest and highest index.
If use water without according with below lowest purity index, there will be too much precipitate on electrode,
which affect the water flow and make the arc not stable.
If use water without according with below highest purity index, there will be problem too. Too high purity
deionized water will leak from cooling system pipe.
