technology and

according to recognised safety standards. If used incorrectly or misused,

however, it can cause:

Injury or death to the operator.

Damage to the device and other material assets bel

onging to the

operating company.

Inefficient operation of the device.

All persons involved in commissioning, operating, maintaining and

servicing the device must:

Be suitably qualified.

Have sufficient knowledge of welding.

Read and follow these operating instructions carefully.

The operating instructions must always be at hand wherever the device

is being used. In addition to the operating instructions, attention must

also be paid to any generally applicable and local regulations regarding

accident prevention and environmental protection.

Before switching on the device, rectify any faults that could compromise

safety.

This is for your personal safety!

Environment

Products are limited to use under suitable conditions. In extreme cases,

the use of products, such as high temperature, low temperature,

thunderstorm weather, will shorten the life of the machine and even

cause damage, please avoid the above situation.

SAFETY

Excessive ambient temperature will cause the machine heat dissipation

is not smooth, so that the internal components of the machine heat

seriously. Usually the maximum operating temperature is 104°F (40°C).

Low temperature may lead to performance degradation or damage of

components insi

de the product, resulting in ice inside the water tank.

Usually the lowest operating temperature is 14°F (-10°C). Please keep

warm and add antifreeze in the water tank if necessary.

Too humid environment may lead to rust of shell and circuit

components. In rainy weather, using products may lead to short circuit

and other abnormalities. Please try to avoid using in the above

environment. If the machine is wet, please dry in time.

Areas

Running parts and specific parts of risk will take damage for your body

or others. The corresponding notices are as follows. It is quite a safe

operation after taking several necessary protection measures.

Items being welded generate and hold high heat and can cause severe

burns. Don’t touch hot parts with bare hands. Al

low a cooling period

before working on the welding gun. Use insulated welding gloves and

clothing to handle hot parts and prevent burns.

A high risk of injury exists when the welding wire emerges from the

welding torch. Always keep the torch well away from the body.

Keep all equipment safety guards, covers and devices in position and in

good repair. Keep hands, hair, clothing and tools away from V-gears,

fans and all other moving parts when starting, operating or repairing

equipment, for example:

Fans

Cogs

Rollers

Shafts

Wire spools and welding wire

SAFETY

By product

Many harmful phenomena, such as noise, bright light and harmful gas,

will inevitably occur in the welding process. In order to avoid harmful

phenomena causing harm to the human body, it is necessary to make

corresponding preparations in advance.

Arc rays from the welding process produce intense visible and invisible

ultraviolet and infrared rays that can burn eyes and skin.

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.

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.

Noise from some processes or equipment can damage hearing. You

must protect your ears from loud noise to prevent perman

ent loss of

hearing.



To protect your hearing from loud noise, wear protective ear plugs

and/or ear muffs. Protect others in the workplace.

Noise levels should be measured to be sure the decibels (sound) do

not exceed safe levels.

The build up of gas ca

n causes a toxic environment, deplete the

oxygen content in the air resulting in death or injury. Many gases use in

welding are invisible and odorless.

Shut off shielding gas supply when not in use.

Always ventilate confine spaces or use approved air-supplied

respirator.

SAFETY

Welding may produce fumes and gases hazardous to health. Avoid

breathing these fumes and gases.



Do not breathe the smoke and gas generated whilst welding or

cutting, keep your head out of the fumes. Use enough ventilation

and/or exhaust

at the arc to keep fumes and gases away from the

breathing zone. Additional precautions are also required when

welding on galvanized steel.



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.



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.



Read and understand the manufacturer’s instructions for this

equipment and the consumables to be used, including the material

safety data sheet and follow your employer’s safety practices.

Explosion

In the process of using, careless operation will lead to fir

e, explosion

and gas leakage or other dangers. Before using the product, we need to

know the correct preventive measures in order to avoid accidents.

Don’t add the fuel near an open flame welding arc or when the engine

is running. Stop the engine and allow it to cool before refueling to

prevent spilled fuel from vaporizing on contact with hot engine parts and

igniting.

Do not spill fuel when filling tank. If fuel is spilled, wipe it up and do not

start engine until fumes have been eliminated.

SAFETY

Flying sparks from the welding arc, hot work piece, and hot equipment

can cause fires and burns. Accidental contact of electrode to metal

objects can cause sparks, explosion, overheating or fire.

Welding sp

arks 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 at the job site, special precautions should be used to

prevent hazardous situation.

Vent hollow castings or containers before heating, cutting or welding.

They may explode.



Sparks and spatter are thrown from the welding arc. Wear oil free

protective garments such as leather gloves, heavy sh

irt, cuff less

trousers, high shoes and a cap over your hair.

Connect the work cable to the work as close to the welding area as

practical. Work cables connected to the building framework or other

locations away from the welding area increase the possibility of the

welding current passing through lifting chains, crane cables or other

alternate circuits. This can create fire hazards or overheat lifting

chains or cables until they fail.

Shielding gas cylinders contain gas under high pressure. If damaged, a

cylinder can explode.



Protect gas cylinders from excessive heat, mechanical shocks,

physical damage, slag, open flames sparks, and arcs.



Insure cylinders are held secure and upright to prevent tipping or

falling over.

Never allow the welding electrode or

earth clamp to touch the gas

cylinder, do not drape welding cables over the cylinder.



Open the cylinder valve slowly and turn your face away from the

SAFETY

cylinder outlet valve and gas regulator.

Cylinder

Use only compressed gas cylinders containing the correct shielding gas

for the process used and properly operating regulators designed for the

gas and pressure used. All hoses, fittings, etc. should be suitable for the

application and maintained in good condition.

Always keep cylinders in an upright position securely chained to an

undercarriage or fixed support.

Cylinders should be located:

Away from areas where they may be struck or subjected to

physical damage.

A safe distance from arc welding or cutting operations and any

other source of heat, sparks, or flame.

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 ha

nd tight

except when the cylinder is in use or connected for use.

Electricity

Touching live electrical parts can cause fatal shocks or severe burns.

The electrode and work circuit is electrically live whenever the output is

on. The input power circuit an

d internal machine circuits are also live

when power is on.

Different products have different requirements for input voltage, such

as single-phase and three-phase. If the machine with three-phase

electricity as input appears phase absence or voltage fluctuation, it may

cause serious damage to the product interior.

All products must be well grounded before they are connected to the

power supply. In case of abnormal case such as shell leakage, please

disconnect the power supply immediately and notify the professionals for

SAFETY

maintenance.

Don’t sling cables or leads around either the body or parts of the body.

The electrode (rod electrode, tungsten electrode, welding wire, etc) must

Never be immersed.

Never be touched when current is flowing.

When the machine is connected to the power supply, there is electricity

inside the machine. Please do not touch the wires, circuit boards and

related electrical parts in order to avoid life hazards and property losses.

During MIG/MAG or TIG welding, the welding wire, the wire spool, the

drive rollers and all metal parts that are in contact with the welding wire

are live. Always set the wire-

feed unit up on a sufficiently insulated

surface or use a suitable, insulated wire-feed unit mount.

EMC

According to the

domestic and international standards, the ambient

devices’ electromagnetism situation and anti-interference ability must be

checked:

Safety device.

Power line, Signal transmission line and Date transmission line.

Date processing equipment and telecommunication equipment.

Inspection and calibration device.

Supporting measures for avoidance of EMC problems:

1. Mains supply

If electromagnetic interference arises despite correct mains connection,

additional measures are necessary.

2. Welding power leads must be kept

as short as possible, must run

close together and be kept well apart from other leads

3. Equipotential bonding

4. Earthing of the workpiece

If necessary, establish an earth connection using suitable capacitors.

5. Shielding, if necessary

Shield off other nearby devices.
