Read instructions.
1. Read the 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 combustible
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. 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 electrical 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.
To protect yourself and others from injury, read and follow these
precautions before installation and operation.

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 various 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.

3. INSTALLATION
3.2 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.
Weld againOverheating Stop working Wait 15 minutes
for unit to cool
Reduce amperage or
reduce duty cycle

3. INSTALLATION
3.3 Machine Installation
1. Open the package and find out the Manual.
2. Check the details of accessories according to packing list that attached to this
manual.
3. Properly install this equipment as following diagram. Inspect the unit for any
damage. If so, contact your local distributor or service agency.
4. The unit should not be located under sunshine. The worksite should be in low
humidity and without dust.
5. Operating Temperature range: -10°C to +40°C.
6. Storage Temperature range: -25°C to +56°C.
7. At least 20cm of space for airflow, 30cm of space for two units located side by
side.
8. Use tent to protect the machine from stormy weather when operate outdoor.
9. Welding produces fumes and gases, breathing these fumes and gases can be
3
hazardous to your health. If inside, less than 300m, Ventilate the area.
