Work Area Precautions
1. Keep your work area clean and well lit. Cluttered
benches and dark areas invite accidents.
2. Do not operate power tools in explosive atmospheres,
such as in the presence of flammable liquids, gases, or
dust. Power tools create sparks which may ignite the dust
or fumes.
3. Keep bystanders, children, and visitors away while
operating a power tool. Distractions can cause you to lose
control. Protect others in the work area from debris such as
chips and sparks. Provide barriers or shields as needed.
Electrical Safety
1. Grounded tools must be plugged into an outlet properly
installed and grounded in accordance with all codes and
ordinances. Never remove the grounding prong or modify
the plug in any way. Do not use any adapter plugs. Check
with a qualified electrician if you are in doubt whether the
outlet is properly grounded. If the tool should electrically
malfunction or break down, grounding provides a low
resistance path to carry electricity away from the user.
2. Double insulated tools are equipped with a polarized
plug (one blade is wider than the other). This plug will fit
in a polarized outlet only one way. If the plug does not fit
fully in the outlet, reverse the plug. If it still does not fit,
contact a qualified electrician to install a polarized outlet.
Do not change the plug in any way. Double insulation
eliminates the need for the three wire grounded power
cord and grounded power supply system..
3. Avoid body contact with grounded surfaces such as
pipes, radiators, ranges, and refrigerators. There is an
increased risk of electric shock if your body is grounded.
4. Do not expose power tools to rain or wet conditions.
Water entering a power tool will increase the risk of electric
shock.
5. Do not abuse the Power Cord. Never use the Power
Cord to carry the tool or pull the Plug from an outlet.
Keep the Power Cord away from heat, oil, sharp edges,
or moving parts. Replace damaged Power Cords
immediately. Damaged Power Cords increase the risk of
electric shock.
6. When operating a power tool outside, sue an outdoor
extension cord marker “W-A” or “W”. These extension
cords are rated for outdoor use, and reduce the risk of
electric shock.
PERSONAL SAFETY
1. Stay alert. Watch what you are doing, and use common
sense when operating a power tool. Do not use a power
tool while tired or under the influence of drugs, alcohol,
or medication. A moment of inattention while operating
power tools may result in serious personal injury.
2. Dress properly. Do not wear loose clothing or jewelry.
Contain long hair. Keep your hair, clothing, and gloves
away from moving parts. Loose clothes, jewelry, or long
hair can be caught in moving parts.
3. Avoid accidental staring. Be sure the Power Switch is
o before plugging in. Carrying power tools with your
finger on the Power Switch, or plugging in power tools with
the Power Switch on, invites accidents.
4. Remove adjusting keys or wrenches before turning the
power tool on. A wrench or a key that is left attached to
a rotating part of the power tool may result in personal
injury.
5. Do not overreach. Keep proper footing and balance
at all times. Proper footing and balance enables better
control of the power tool in unexpected situations.
Use safety equipment. Always wear eye protection.
Dust mask, non-skid safety shoes, hard hat, or hearing
protection must be used for appropriate conditions.
Tool Use and Care
1. Use clamps (not included) or other practical ways to
secure and support the workpiece to a stable platform.
Holding the work piece by hand to against your body is
unstable and may lead to loss of control.
2. Do not force the tool. Use the correct tool for your
application. The correct tool will do the job better and
safer at the rate for which it is designed.

Page 3
1. Do not use the power tool if the Power Switch does not
turn it on or o. Any tool that cannot be controlled with
the Power Switch is dangerous and must be replaced.
2. Disconnect the Power Cord Plug from the power source
before making any adjustments, changing accessories, or
storing the tool. Such preventive safety measures reduce
the risk of starting the tool accidentally.
3. Store idle tools out of reach of children and other
untrained persons. Tools are dangerous in the hands of
untrained users.
4. Maintain tools with care. Keep cutting tools maintained
and clean. Properly maintained tools are less likely to bind
and are easier to control. Do not use a damaged tool. Tag
damaged tools “Do not use” until repaired
Check for misalignment or binding of moving parts,
breakage of parts, and any other condition that may
aect the tool’s operation. If damaged, have the tool
serviced 1. before using. Many accidents are caused by
poorly maintained tools.
2. Use only accessories that are recommended by the
manufacturer for your model. Accessories that may be
suitable for one tool may become hazardous when used on
another tool.

About the machine
MMA series welding machine is a rectifier adopting the most advanced inverter
technology.
The development of inverter gas-shielded welding equipment profits from the
development of the inverter power supply theory and components. Inverter
gas-shielded welding power source utilizes high-power component IGBT to transfer
50/60HZ frequency up to 50KHZ, then reduce the voltage and commutate, and output
high-power voltage via PWM technology. Because of the great reduce of the main
transformer’s weight and volume; the efficiency increases by 30%. The appearance of
inverter welding equipment is considered to be a revolution for welding industry.
MMA series welding power source can offer stronger, more concentrated and
more stable arc. When stick and work piece get short, its response will be quicker. It
means that it is easier to design into welding machine with different dynamic
characteristics, and it even can be adjusted for specialty to make arc softer or harder.
MMA welding machine has the following characteristics: effective, power saving,
compact, stable arc, good welding pool, high no-load voltage, good capacity of
force compensation and multi-use. It can weld stainless steel, alloy steel, carbon steel,
copper and other color metal. It can apply to electrode of different specifications and
materials, including acidity, alkalescence, and fibre. It can apply in high altitude, the
open air and inside and outside decoration. Compared with the same products of home
and abroad, it is compact in volume, light in weight, easy to install and operate.
Thanks for purchasing product and hope for your precious advice. We will dedicate to
produce the best products and offer the best service.
CAUTION！
The machine is mainly used in industry. It will produce radio wave, so the
worker should make fully preparation for protection.

equipment. When power voltage moves between±15% of rated voltage, it still can
work normally.
When use long cable, in order to prevent voltage form going down, bigger section
cable is suggested. If cable is too long, it may affect the performance of the power
system. So we suggest you to use configured length.
1、Make sure intake of the machine not blocked or covered, lest cooling system
could not work.
2. Use inducting cable whose section is not less than 6 mm² to connect the
housing to the ground. The way is from the ground-connecting screw at the back to
the earth device.
3. Correctly connect the arc torch or holder according to the sketch. Make sure the cable,
holder and fastening plug have been connected with the ground. Put the fastening plug into
the fastening socket at the “-“polarity and fasten it clockwise.
4. Put the fastening plug of the cable to fastening socket of “+” polarity at the front
panel, fasten it clockwise, and the earth clamp at
the other terminal clamps the work piece.
5. Please pay attention to the connecting
polarity, DC welding machine has two
connecting ways: positive connection and
negative connection. Positive connection:
holder connects with “-“ polarity, while work
piece with the “+”polarity. Negative
connection: work piece with the “-“ polarity,
holder with the “+” polarity. Choose suitable
way according to working demands. If
unsuitable choice, it will cause unstable arc,
more spatters and conglutination. If such
problems occur, please change the polarity of the fastening plug.
6.According to input voltage grade, connect power cable with power supply box of
relevant voltage grade. Make sure so mistake and make sure the voltage difference
among permission range. After the above job, installment is finished and welding is
available.
If distance of work piece and machine is too far (50 - 100m), and the cables
(torch cable and earth cable) are too long, please choose cable of bigger
section to minimize the reduction of the voltage.

7. Hold the MMA welding rod down and tilt the rod forward.
8. Stroke the work piece lightly to ignite the arc. Does not
strike like a match? Never tap the electrode wire to ignite the
arc; it will damage the rod.
9. When the arc ignites, tilt the electrode forward and hold it
near the work piece.
If too much current is drawn from the welder; the Thermal
Overload protector will 1. activate, the Overload indicator or
will light, and the welder will turn o until it cools down. It
will automatically reset.
Welding current
Welding current level is determined by the size of electrode
- the normal operating range and current are recommended
in the manual. Typical operating ranges for a selection of
electrode sizes are illustrated in the table. As a rule of thumb
when selecting a suitable current level, an electrode will
require about 40A per millimeter (diameter). Therefore, the
preferred current level for a 4mm diameter electrode would
be 160A, but the acceptable operating range is 140 to 180A.

MANUAL METAL ARC (MMA) WELDING
Shielded metal arc welding (SMAW), also known as manual metal arc (MMA) welding, and flux-shielded arc welding
or informally as stick welding, is a manual arc welding process that uses a consumable electrode coated in flux to lay
the weld. An electric current, in the form of either alternating current or direct current from a welding power supply, is
used to form an electric arc between the electrode and the metals to be joined. As the weld is laid, the flux coating of the
electrode disintegrates, giving o vapors that serve as a shielding gas and providing a layer of slag, both of which protect
the weld area from atmospheric contamination.
Because of the versatility of the process and the simplicity of its equipment and operation, shielded metal arc welding
is one of the world’s most popular welding processes. It dominates other welding processes in the maintenance and
repair industry, and though flux-cored arc welding is growing in popularity, SMAW continues to be used extensively in
the construction of steel structures and in industrial fabrication. The process is used primarily to weld iron and steels
(including stainless steel) but aluminum, nickel and copper alloys can also be welded with this method.
To strike the electric arc, the electrode is brought into contact with the work piece by a very light touch with the
electrode to the base metal then is pulled back slightly. This initiates the arc and thus the melting of the work piece and
the consumable electrode, and causes droplets of the electrode to be passed from the electrode to the weld pool. As
the electrode melts, the flux covering disintegrates, giving o shielding gases that protect the weld area from oxygen
and other atmospheric gases. In addition, the flux provides molten slag which covers the filler metal as it travels from
the electrode to the weld pool. Once part of the weld pool, the slag floats to the surface and protects the weld from
contamination as it solidifies. Once hardened, it must be chipped away to reveal the finished weld. As welding progresses
and the electrode melts, the welder must periodically stop welding to remove the remaining electrode stub and insert a
new electrode into the electrode holder. This activity, combined with chipping away the slag, reduce the amount of time
that the welder can spend laying the weld, making SMAW one of the least ecient welding processes. In general, the
operator factor, or the percentage of operator’s time spent laying weld, is approximately 25%.
The actual welding technique utilized depends on the electrode, the composition of the work piece, and the position
of the joint being welded. The choice of electrode and welding position also determine the welding speed. Flat welds
require the least operator skill, and can be done with electrodes that melt quickly but solidify slowly. This permits higher
welding speeds. Sloped, vertical or upside-down welding requires more operator skill, and often necessitates the use of
an electrode that solidifies quickly to prevent the molten metal from flowing out of the weld pool. However, this generally
means that the electrode melts less quickly, thus increasing the time required to lay the weld.
