SAFETY WARNING
On the process of welding or cutting, there will be possibility of injury, so please
take protection into consideration during operation. For more details please review
the Operator Safety Guide, which complies with the preventive requirements of the
manufacturer.
Electric shock - May lead to death!!
• Set the earth tting according to applying standard.
• Do not touch the bare electric parts and electrode with uncovered skin, wet gloves or clothes.
• Make sure you are insulated from the ground and the workshop.
• Make sure you are in safe position.
Gases and fumes - May be harmful to health!!
• Keep your head out of the gases and fumes.
• When arc welding, ventilators or air extractors should be used to avoid breathing gases.
Arc rays - Harmful to your eyes, burn your skin
• Wear suitable protective mask, light lter and protective garment to protect eyes and body.
• Prepare suitable protective mask or curtain to protect looker-on.
Fire
• Welding sparks may cause a re, make sure there are no ammable objects or chemicals nearby.
Noise - Excessive noises will be harmful to hearing
• Use haring protection or others means to protect ear.
• Warn looker-on that noise is harmful to hearing.
Having trouble? Connect with authorized professionals
• If trouble happens during installation and operation, please follow this manual instruction
to check up.
• If you fail to fully understand the manual, or fail to solve the problem with the instruction, you
should contact the suppliers or the service center for professional help.
WARNING!
Thermal Magnetic Auto Circuit Breaker protecting switch
should be used with the machine.

• Repair and maintenance to be performed by authorized personnel only.
• The welding machine is to be maintained in good operational conditions (dry and clean).
• The welding machine is not to be positioned in a closed space or next to a wall while welding
in order to avoid problems with venting.
• The welding machine is to be properly connected to the power grid.
• avoid pulling on the power cable when moving the welding machine.
• the welding handle and work cable are to be properly maintained.
• Electricity is dangerous and loose connections can lead to injury and poor welding.

The welding arc emits sparks, fumes and radiation
• Remove all ammable materials and items from your work area.
• Ensure proper ventilation at the work area.
• Do not weld tanks or pipes that contain or used to contain ammable liquid or gas (danger of
explosion or re) or were cleaned by chlorine-based detergents (danger of toxic fumes).

• Avoid coming in direct contact with the welding circuit. The open circuit voltage between the
electrode holder, the work cable and the work piece is dangerous.
• Do not weld when it is raining or in wet or damp places.
• Always use protective equipment DIN 9-10, including long sleeved pants and vest, gloves,
welding helmet of proper rating and hat. Avoid exposing the skin to the welding UV radiation.

The machine is designed to use 11lb spools (8" outer diameter)
The wire spools are not supplied with the machine and must be purchased separately.
Make sure the shielding gas and electrical power are disconnected.
• Use a CO2 or mixed gas Cylinder equipped with a pressure regulator. Connect the exible hose
between the regulator and the machine (17). Tighten the bands.
• Connect the ground cable quick connection between the machine (negative terminal (16)
when using solid wire) and the work piece.
• Mount the wire spool (B) over the shaft (C) and tight with the nut (F).
• Choose the proper feeder grooved wheel (1 or 2) according to the wire diameter used.
• Release the screw in the feeder mechanism and insert the wire through the tube. Close and
tighten the screw to have the feeder wheel hold the wire in place.
• Connect the MIG torch cable quick connector over the protruding wire. Feed the wire all
through to the torch, and screw a contact tip over it.

t2~t3: During the whole welding process, the gun switch is pressed and held without releasing;
t3: Release the gun switch, the output current slopes down;
t3~t4: The output current slopes down to minimum current (5A), stop arc; adjustment range of
down slope time: 0~5S;
t4~t5: Post ow time, adjustment range of post ow time: 0.1~10.0S;
t5: Electromagnetic valve is closed and stop argon owing. Welding is nished.
Short circuit protect function:
1. TIG /DC/LIFT: If the tungsten electrode touches the workpiece when welding, the current will
drop to 30A, which can reduce the tungsten spoilage and signicantly prolong the life of the
tungsten electrode and prevent tungsten clipping.
2. STICK operation: if the electrode touches workpiece over two seconds, the welding current
will drop to 0 automatically to protect the electrode.
Notices:
• Check the condition of welding and connection units rstly, otherwise there will be malfunction
such as ignition spark/gas leakage/out of control and so on.
• Check that whether there is enough Argon gas in the shield gas cylinder, you can test the
electromagnetic gas valve through the switch on the front panel.
• The ow rate is set according to the welding power used in the job. Turn the regulation
screw to adjust the gas ow which is shown on the gas hose pressure meter or the gas bottle
pressure meter.
