4

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 having to dismantle some parts of the device during maintenance, but must keep safety awareness

strongly every time.

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.

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 with doctor’s permission would help to keeping healthy.
