and proper operation training are necessary to prevent injury

accidents.

Aprotective helmet with a shading filter must be worn to protect the face and

eyes during welding and cutting operations or when watching welding/cutting

operations.

Wear a helmet with the correct filter and cover plate to protect the eyes, face,

neck and ears from arcing sparks and bright light during welding operation or

observation. Warn bystanders not to look at the arc and not to expose their

skin in the area of strong light arc or high temperature spark

Wear flame retardant gloves, flame retardant welding/cutting overalls, flame

retardant shoes, and welding/cutting helmets or protective caps to protect

against arcing bright lights, high temperature sparks or hot metal particles. A

flame retardant apron is also available to protect against thermal radiation

and high temperature sparks.

Hot sparks or metal can get into rolled-up sleeves, trouser legs or pockets.

Before welding/cutting, sleeves and collars should be buttoned, and clothes

with front pockets should not be worn.

- 5 -

Use appropriate flame retardant shields or curtains to protect other persons

from arc radiation and high temperature sparks.

Welding slag has high temperature, and can be splashed over a long

distance. During the removal of welding slag, the operator and viewers

should wear additional safety goggles over safety glasses.

It is forbidden to touch the welding work piece with bare hands to avoid

accidental scald and burn.

Fire and explosion precaution

During welding and cutting, high temperature flame and arc will be

generated, which will cause fire; high temperature welding slag and

sparks will also cause fire and explosion.

Protect yourself and others from flying sparks and hot metal

Flammable and explosive items are not allowed to be placed in the

welding/cutting area. Flammable materials that needed to be used in

welding/cutting process must be covered with flame retardant materials.

Hot sparks and metal can fly into cracked floors and walls, which need to be

protected against fire hazards.

Do not weld and cut on sealed high-pressure gas tanks, which may cause

explosions.

Fire extinguishing equipment, such as fire hose, water bucket, sand bucket

or portable fire extinguisher, must be provided in the welding and cutting

area. Furthermore, regularly check the effectiveness of these fire

extinguishing equipment, and carry out the training on the safe use of these

fire extinguishing equipment.

After finishing the welding/cutting operation, check whether there is high

temperature spark or metal, which might cause fire and timely dispose. If

necessary, go to the firefighter for help.

Prevention of Electric Shock Injuries

A person contacting with live electrical components or machine can

produce an electric shock, which will cause serious injury to the

human body or death. Do not use welding/cutting machines in

humid environment where movement is limited or there is a risk of

falling.

Ensure reliable grounding of the machine to prevent electric shock accident

caused by electric leakage.

Make sure that the work piece connected to the ground clamp of the machine

is reliably grounded.

Connect the ground clamp with the work piece reliably, or it might cause

electric shock accident.

Check the wires and cables frequently, and replace it in time if the insulation

layer is damaged.

Keep everything dry when welding/cutting, including clothing, working area,

cables, flashlights, electrode stand and power supply.

Make sure that every part of your body will not contact with the live electrical

parts.

Never stand directly on metal or the ground when have to work in a narrow or

humid environment. Please stand on dry wood or insulating platform,

wearing shoes with insulated rubber sole.

Please wear dry gloves without holes when turn on the machine power.

Please turn off the machine before taking off the gloves.

It is forbidden to replace the ground cable of the machine with other wires

and cables.

There is high voltage inside the machine. Non-professionals are strictly

forbidden to open the casing or start the machine for maintenance.

Protective Measures for Electromagnetic Fields

When an electric current flows through a conductor, it generates an

electromagnetic field, which can be harmful to the human body.

Welders with cardiac pacemakers shall consult a doctor if they are suitable

for welding and cutting operations.

- 7 -

Human exposed to the electromagnetic field may cause unknown health

effects.

Welders should minimize electromagnetic field damage through the following

methods.

3.1

Wrap the electrodes and the working cable with insulating cloth and secure

them with tape if possible.

3.2

Do not wrap wires and cables around arms.

3.3

Do not put cables around your body. Put the cables on one side if possible.

3.4

The clamping position on the work piece, by the working cable, should be as

close as possible to the area to be welded or cut.

3.5

The welding/cutting machine and cable shall not be close to the body during

operation.

Protection Against Fumes and Gas

Welding and cutting produces a lot of fumes and gas, which is

harmful to human health.

Keep your head out of the fumes. Do not breathe the fumes.

Keep well ventilation in welding/cutting working environment. Do not weld or

cut in a confined space and there must be an air exhaust and dust remove

system.

Do not weld in locations near degreasing or spraying operations. The heat

and arc produced in the operation can react with chlorinated hydrocarbon to

form highly toxic and irritating gases, which is harmful to the human body

and might cause birth defects, and in some cases, can lead to cancer.

If you experience temporary eye, nose, or throat discomfort during

welding/cutting operation, it may be caused by inadequate ventilation.

Please stop the operation immediately and take measures to improve

ventilation in the working area.

For specific ventilation requirements of welding and cutting working area,

please refer to relevant documents of welder profession.

Gas Cylinder Safety

Cylinders connected to welding/cutting equipment may rupture and

leak gas, if not being properly operated. A sudden rupture of a

cylinder valve or relief valve can cause injury or even death to

human body.

The cylinder should be away from high temperature and fire source. Do not

use hard objects to scratch on the cylinder body.

A suitable gas should be selected and stored in the cylinder during welding

and cutting. The pressure reducing valve should be installed on the cylinder

according to the cylinder manufacturer's operating instructions. Do not use

quick connectors for cylinder gas hose connection and please make sure

that the gas hose and fittings is reliably connected, without any leakage.

Keep cylinders fixed upright at all times and the cylinder can be chained or

belted to a suitable trolley, base, wall, post or shelf. Never fix the cylinder to

the work table or machine, to avoid they become part of the circuit.

Ensure that the cylinder valve is closed when it is not in use. If there is no

hose connected to the cylinder, put a dust cap on the valve port in time.

Moving Parts Safe Protection

Moving parts, such as fans, rotors and belts, can be

hazardous.

Before welding/cutting, keep all doors, panels, covers closed.

Only qualified professionals and technicians can remove the machine casing

for maintenance.

Make sure that hands, hair, clothing and tools are out of movement range of

the moving parts
