Safety Tips
Consider the following tips to ensure safe operation of your welding/cutting equipment:
Ensure that this welding equipment is installed in an area free of corrosive chemical gases,
flammable gases or materials, and explosive chemicals.
The area should contain little dust, and have a humidity of no more than 80%.
Operate the welding equipment in an area sheltered from direct sunlight and precipitation.
Work area temperature should be maintained at -10C to +40C;
If, because of an overload, the machine suddenly stops, and it is necessary to restart it, leave
the internal fan operating to lower the inside temperature.
Always wear protective clothing and a welding mask to protect your skin.
Wear safety goggles designed to darken the arc generated by your machine.
Wear suitable noise protection to protect your hearing.
Ensure that machine is grounded through the power cord or on the machine case.
Never operate the machine in bare feet or on a wet floor.
Never switch the machine off while it’s in use. Doing so will damage the internal circuitry.
Ensure that your circuit breaker is rated to handle the current requirements of your machine.
Use a UL approved receptacles and plugs with your machine. Never hard wire the machine to
main power.
Work in a well-ventilated area to avoid smoke. Keep your head out of the smoke. Ensure that
air is flowing away from you to avoid inhaling smoke.
Ensure proper ventilation through the machine’s louvers. Maintain a distance of at least
12 inches between this cutting equipment and any other objects in the work area.
Use a screen or curtain designed to keep passer byes from viewing the arc.
The arc spray and metal spray from machine use may cause nearby fires. Use caution.
 If, after reviewing this manual, you have any problems in setting up or operating your
machine, contact us at [e-mail].

WARNING ARC WELDING can be hazardous
When using tool, basic safety precautions should always be followed to reduce the risk of
personal injury and damage to equipment Read all instructions before using this tool!
ELECTRIC SHOCK can KILL
Improper use of electric arc welders can cause electric
shock ,injury,and death! Take all precautions described in
this manual to reduce the possibility of electric shock.
FUMES AND GASES
Fumes and gases can be dangerous do net breathe fumes
that are produced by the arc welding operation .These fumes
are dangerous. Keep the head and face out of the welding fumes
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.
WELDING SPARKS
Welding sparks can cause fire or explosion. DO not operate
any electric arc welder in areas where flammable or explosive
vapors may be present. Take precautions to be sure that flying
sparks and heat do not cause flames in hidden areas, cracks, etc.
Always keep a fire extinguisher accessible while performing arc
welding operations. Before starting or servicing any electric arc
welder, read and understand all instructions. Failure to follow safety
precautions or instructions can cause equipment damage and/or serious personal injury
or death. All installation, maintenance, repair and operation of this equipment
should be performed by qualified persons only in accordance with
national, state, and local codes

ARC RAYS can burn.
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. Head shield and filter lens should conform to ANSI Z87
standards.
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.
Heat metal can burn
Electric arc welding operations cause sparks and heat metal to
temperatures that can cause severe burns[ Use protective gloves and
clothing when performing any metal working operation.
Make sure that all persons in the welding area are protected from heat,
sparks, and ultraviolet rays. Use additional face shields and flame resistant
barriers as needed.
Never touch work pieces until completely cold.
ELECTRIC AND MAGNETIC FIELDS
Electric and magnetic fields may be dangerous. The electromagnetic field
that is generated during arc welding may interfere with the operation of
various electrical and electronic devices such as cardiac pacemakers.
Persons using such devices should consult with their physician prior to
performing any electric arc welding operations.
Route the wire gun and work cables together and secure with tape when
possible. Never wrap arc welder cables around the body.
Always position the wire gun and work leads so that they are on the same side of the body.
Exposure to electromagnetic fields during welding may have other health effects which are not known.
CYLINDER may explode if damaged.
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 hand tight except when the cylinder is in use or connected for
use.
Carefully read the operation manual prior to using, installing and maintaining the electric
welding machine for the purpose of preventing damages such as fire, electric shock and etc. from
occurring. Please keep the manual for the reference in the future

prevent the wire from unwinding.
3. Cut Off bent end of wire, leaving 100mm long straight section
4. Gently pull open the idle roll assembly to expose the drive roll grove. Guide straightened wire through inlet
wire guide (4) and toward drive roll groove (3).
While holding open the idle roll (5), slide end of wire through drive roll's groove and toward gun tube liner
(1).
5. Release the idle roll assembly and the straightened wire.
Welding Procedure
1 .Connect input power to the machine.
2, Screw off the nozzle and contact tip,
3~ Press the trigger, then the driver feeds the wire into the gun, Release the trigger when wire come out from
the mouth of the gun,
4. Screw on the contact tip and nozzle.
5. Cut off the aluminum wire so that it extends about 1/4 inches (6-10mm) from the contact tip.
When welding
1. Select suitable wire and gas
according to the type and thickness of
the work piece refer to related Welding
Manual.
2. According to the wire and thickness
of the work piece set wire speed and
