Read instructions.

1、Read owner's Manual before using or

servicing unit。

2、Use only manufacturer’s supplied

replacement。

Exploding parts can injure.Always

wear a face shield and long sleeves。

Static can damage PC boards

1、Put on grounded wrist strap before

handing boards or parts。

2、Use proper static-proof bags and

boxes to store，move or ship PC boards。

Fire or explosion hazard.

Do not locate unit on,over,or near combustibe

surfaces.Do not install unit near flammables.

1、Wear approved face shield or safety

goggles with side shields。

2、Wear proper body protection to protect skin。

Do not weld in the height！

Flying metal can injure eyes。

1)Wear safety glasses with side shields or

face shield。

1、Magnetic fields can affect pacemakers.

Pacemaker wearers keep away.

2、Wearers should consult their doctor

before going near plasma arc cutting

operations。

Overuse can cause overheating

Allow cooling period ,follow rated duty

cycle before starting to weld again.

Cylinders can explode if damaged.Gas

cylinders contain gas under high pressure.

If damaged,a cylinder can explode .Be sure

to treat them carefully.

Electric shock can kill:

1、Do not touch live electrical parts。

2、Wear dry,hole-free insulating gloves

and body protection.

3、Do not wrap electrical cable around your body.

4、Ground the workpiece with a good elect-

rical ground。

Keep away from the torch tip.

Remove all flammables of the welding area.

Falling unit can cause injury.

Eye protection for welding:

Current level in amperage Minimum shade

Number

30-150A---------------------------- #8

150-300A--------------------------- #10

300-500A--------------------------- #12

The heat from the workpiece can cause serious

burns。

Never cut on pressurized cylinder.

Keep away from moving parts such as fans.

Fumes and gases can be hazardous.

welding produces fumes and gases. Breathing

these fumes and gases can be hazardous to

your health.

If inside,ventilate the area.

Do not weld in a confined space only if it

is well ventilated.

Moving parts can cause injury.

Maintenance regularly！

Factory safety！

Description:

Our semi-automatic welder is an all-in-one MIG shielding gases welder (GMAW) with high

efficiency that is an ideal substitute for manual arc welding.

Most advanced circuit design and technology are adopted.Excellent performances,supreme reliability,

quality welding requirements can be satisfied.Spot weld,groove weld,and fillet weld are available.Most

commonly used shielding gases are applicable such as Co2,AR,CO2+AR,CO2+O,etc.

Suitable for welding of variou metallic materials such as mild steel,low carbon steel,low alloy steel,

stainless steel, steel,iron,copper, aluminum,nicket,etc.

Extensively used in the welding and field operation of oil pipeline,chemical,car fabrication,shipyard,

etc.

2.Duty Cycle And Overheating

1.Overheat protection is installed on the aluminium board of main

transformer and rectifier.The unit products heat while welding.

2.If unit overheats ,output stops, and cooling fan runs.

3.Wait fifteen minutes for unit to cool.Reduce amperage or voltage,

or duty cycle before welding.

Overheating Stop working Wait 15 minutes

for unit to cool

Reduce amperage

or reduce duty

cycle

Weld again
