§1 Safety
§1.1 Signal Explanation
The above signals mean warning! Notice! Running parts and getting an electric shock or
thermal parts will take damage for your body or others. The corresponding notices are as follows.
It is quite a safe operation after taking several necessary protection measures.
§1.2 Arc Welding Damage
The following signals and word explanations are to some damages for your body or others
happening on the welding operation. While seeing these, please rem ind of yourself or others to
be dangerous.
Only ones who are trained professional ly can install, debug, operate, maintain and repair the
equipment.
During the operation, non-concerned people should be lift, especially for children.
After shut off the machine power, please maintain and examine the equipment according to §5
because of the DC voltage existing in the electrolytic capacitors.
ELECTRIC SHOCK CAN KILL.
Never touch electrical parts.
Wear dry, hole-free gloves and clothes to insulate yourself.
Insulate yourself from work and ground using dr y ins ulat ion. M ake c ertain the insul ation i s l arge
enough to cover your full area of physical contact with work and ground.
Take carefully when using the equipment in small place, falling-off and wet circumstance.
Never close the machine power before installation and adjustment.
Ensure to install the equipment correctly and ground the work or metal to be welded to a good
electrical (earth) ground according the operati on m anual.
The electrode and work (or ground) circ uits are electrically “hot” when the welder is on. Do not
SAFETY
2
touch these “hot” parts with your bare skin or wet clothing. Wear dry, hole-free gloves to insulate
hands.
In semiautomatic or automatic wire welding, the el ectrode, elec trode reel, weldi ng head, nozz le
or semiautomatic welding gun are also electric ally “hot”.
Always be sure the work cable makes a good electrical connecti on with the metal being welded .
The connection should be as close as possible to the area being welded.
Maintain the electrode holder, work clamp, welding cable and welding machine in good, safe
operating condition. Replace damaged insulat ion.
Never dip the electrode in water for cooling.
Never simultaneously touch electrically “hot” parts of electrode holders connected to two
welders because voltage between the two can be the total of the open circuit voltage of both
welders.
When working abo ve the floor level, use a saf ety belt to protect yoursel f from a fall should you
get a shock.
FUMES AND GASES CAN BE DANGEROUS.
Welding may produce fumes and gases hazardous t o health. Avoid breathing these fum es and
gases. When welding, keep your head out of the fume. Use enough ve ntilation and/ or exhaust at
the arc to keep fumes and gases away from the breathing zone. When welding with el ectrodes
which require special ventilation such as stainless or hard f acing or on lead or cadmium plated
steel and other metals or coatings which produce hi ghly toxic fumes, keep exposure as low as
possible and below Threshold Limit Values using local exhaust or mechanical ventilation. In
confined spaces or in some circumstances, outdoors, a respirator may be required. Additional
precautions are also required when welding on galvanized steel.
Do not weld in locations near chlorinated hydrocarbon vapors coming from degreasing,
cleaning or spraying operations. The heat and rays of the arc can react with solvent vapors to
form phosgene, a highly toxic gas, and other irritating products.
Shielded gases us ed for arc welding can displace air and cause injury or deat h. Always use
enough ventilation, especially in confined areas , to insure breathing air is safe.
Read and unde rstand the manufacturer ’s instructions for this equipment and the c onsumables
SAFETY

to be used, including the material safety data sheet and follow your em pl oyer’s safety practices.
ARC RAYS CAN BURN.
Use a shield with the proper filt er and cover plates to protect your eyes from sparks and the
rays of the arc when welding or observing open arc welding.
Use suitable clothing made from durable flame-resistant material to protect your s kin and that
of your helpers from the arc rays.
Protect other nearby personnel with suitable, non-flammabl e screening and /or warn them not
to watch the arc nor expose themselves to the arc rays or to hot spatter or metal.
SELF-PROTECTION
Keep all equipment safety guards, covers and devices in position and in good repair. Keep
hands, hair, clothing and tools away from V-belts, gears, fans and all other moving parts when
starting, operating or repairing equipment.
Do not put your hands near the en gine fan. Do not attempt to overri de the governor or idler by
pushing on the throttle control rods while the engin e i s running.
DO NOT adds the fuel near an open flame welding arc or when the engine
is running. Stop the engine and allow it to cool before refueling to prevent spilled fuel from
vaporizing on contact with hot engine parts and igniting. Do not spill fuel when filling tank. If fuel
is spilled, wipe it up and do not start engine until fumes have been eli minated.
WELDING SPA RK S can cause f ire or explosion.
Remove fire hazards from the weldi ng area. If this is not possible, cover them to prevent th e
welding sparks from starting a fire. Remember that welding sparks and hot materials from
welding can easily go through small crack s and openings to adjacent areas. Avoid welding nea r
hydraulic lines. Have a fire extinguisher readil y available.
Where compressed gases are to be used at the job sit e, special precautions s hould be used t o
SAFETY
4
prevent hazardous situation.
When not welding, make c ertain no part of the electrode circuit is touching the work or ground.
Accidental contact can cause overheating and create a fire hazard.
Do not heat, cut or weld tanks, drums or containers until the proper steps have been taken to
insure that such procedures will not cause flammable or toxic vapors from substances inside.
They can cause an explosion even though they have been “cl eaned”.
Vent hollow castings or containers before heating, cutting or welding. They may explode.
Sparks and spatter are thrown from the welding arc. Wear oil free protective garments such as
leather gloves, heavy shirt, cuff less trousers, high shoes and a cap over your hair. Wear ear
plugs when welding out of position or in confined plac es. Always wear safety glasses with side
shields when in a welding area.
Connect the work cable to the work as close to the welding area as practical. Work cables
connected to the building framework or other l ocations away from the wel ding area increase the
possibility of the welding current passing through lifting chains , crane cables or other alternate
circuits. This can create fire hazards or overheat lifting chains or cables until they fail .
UNSECURED CYLINDERS may be dangerous.
Use only compressed gas cylinders containing the correct shielding gas and properly oper atin g
regulators designed for the gas and cylinder pressure.
Always keep cylinders:
- Upright position securely chained to an undercarriage or f i xed support.
- Away from areas where they may be struck or subjected to physical damage.
- A safe distance from welding or cutting operations and any other source of heat, sparks, or
flame.
Keep your head and face away from the cylinder valve outlet when opening.
Valve protection caps should always be in place and hand tight except when t he cylinder is in
use or connected for use.

§1.3 Knowledge of Electric and Magnetic Fields
Electric current flowing through any conductor causes loc alized Electric and Magnetic Fields
(EMF). The discussion on the effect of EMF is ongoing all the world. Up to now, no material
evidences show that EMF may have effects on health. However, the research on damage of EMF
is still ongoing. Before any conclusion, we should m i nimize exposure to EMF as few as possible.
In order to minimize EMF, we should use the following procedures:
Route the electrode and work cables together – Sec ure them with tape or sleeve.
All cables should be kept as far away from the operator as possible.
Never coil the power or earth cables around operat or body.
Connect the work cable to the workpiece as close as pos sible to the area being welded.
The people with heart-pacemaker should be away from the welding area.

§2 Overview
§2.1 Brief Introduction
The M-Series of MIG, MAG INVERTER arc welding machine adopts the latest pulse width
modulation (PWM) technology and insulated gate bipolar transis tor (IGBT) power module, which
can change work frequency to medium frequenc y so as to replace the traditional hulking work
frequency transformer with the compact medium frequency transformer. This technology provides
a compact, lightweight, portable power supply with high output p ower and superior efficiency.
M-Series arc welding m achines are designed to use active gas（Ar+O
2
、Ar+CO2 and inactive
gas（Ar) for MIG/MAG welding or Flux-Cored wire for non-shield gas welding.
The MGI Series arc welding machine has automatic protection functions with intelligent to
over-voltage, over-current and over-heat sensing with auto-reset. If any one of the above
problems happens, the alarm lamp on the front panel will illuminate and output current will be
shut off automatically to protect itself and prolong the equipment usi ng l i fe.
M-SERIES Features:
1. Digital control system with infinitely adjustable (non-step) settings for power & wire speed
2. Electronic inverter power source provides high performance and efficiency
3. Waveform control provides stable welding arc on all materials and power settings
4. IGBT technology insures low power dissipation in compact package
5. Superior 40% duty cycle inverter design for profes sional welding.

§2.2 Working Principle
The working principle of M-SERIES arc welding machine is shown as the following figure.
single-phase 110 or 220V work frequency AC is recti fied into DC（154V）, then is converted to
medium frequency AC (about 37KHz) by inverter device (IGBT), after reducing voltage by
medium transformer (the main transformer) and rectifying by medium frequency rectifier (fast
recovery diodes), and is outputted by inductance filtering. Meanwhile, the welding current
parameter can be adjusted infinitely to meet with the requirements of welding application.
§2.3 Volt-Ampere Characteristic
The inverter has an excellent volt-ampere characteristic, whose graph is shown as the
following figure. The relation between the rated loading voltage U

§3.2 Duty cycle and Over-temp
The rated duty cycle is defined as the proportion of the time that a machine can work
continuously over a 10 minute cycle when set at 100% of rated output welding current in 40C
(104F) ambient environment.
When the transformer reac hes an over-heat condition, the heat sensor inside it will open and
will output an instruction to circuit board to cut AC relay and the output welding current while
illuminating the over-heat pilot lamp in the f ront panel. At this time, all welding operations should
cease for 15 minutes al lowing the cooling fan to reduce the temperature. The unit will auto-reset
when correct temperature has been achieved and pilot light will go out. If the machine r eached
the over-temp capacity again, the welding output current or the arc cycle should be reduced.

§5.3 Wire Feeding Maintenance
The welding wire must travel smoothly and freely from the spool all the way to the weld pool for
controlled welding. Poor welding performance is many times a result of mechanical feeding
problems with the wire through the torc h. Check for smooth feeding without welding by holding
gun 1’ from wood surface and feeding wire at 60-degree angle. It should feed smoothly as it
bows up from the surface. If not, maintenance needs t o be performed.
1. Drive Roll: Check the wear of the feed roll “V” groove and clean the groove with wire
brush and/or compressed air.
2. Idle Roll: Check for signs of wear and good bearing support. Change i s necessary.
3. Wire Guide: Pressure of the feed rolls removes copper plating from the welding wire’s
surface which then finds its way to the wire guide. If the wire guide is not cleaned, it
gradually clogs up and causes wire feed malfunctions. Clean the wire guide in the
following manner：
a. Cut the wire and remove the welding gun from the feeder.
b. With a pneumatic pistol, blow compressed air t hrough the wire guide.
c. Blow the wire feed mechanism and reel housing clean with compressed air.
d. Reattach the torch, install wire, feed wire, install and tighten the contact tip with
wrench and install nozzle.
4. Wire Liner Replacement: If the wire liner in the MIG gun cable is too worn or totally
clogged, change it to a new one according to the following instructions:
a. Remove MIG gun mounting nut which exposes the brass liner nut.
b. Remove liner nut and withdraw the wire conduit liner from the gun cable.
c. Push a new liner in to the gun making sure that it enters all the way to the contact
tip’s base. Trim to length to lightly contact base of tip.
d. File the sharp edges of the cut-off end round for smooth feeding
e. Tighten the wire liner nut in place and reattach the gun to machine.
f. Feed wire through gun and reinstall contact tip, tighten with wrench.

§5.4 Changing the Feed Roll
The wire feed roller is factory set for welding filler wires 0.8 – 0.9mm (.030” - .035”). The
roller has a 0.6mm (.023”) diameter groove on the other side; therefore, the feed roller si de must
be changed if you use 0.6mm thick filler wire. In order to thread the filler wire, follow these steps:
1. Open the wire cabinet housing by pressing on the opening button and install the wire
spool in such a way that it rotates counter clockwise. You can use either a diameter
200mm (8”) or 100mm (4”) wire reel in the machine.
2. Attach the reel onto the spool holder being sure to locate drive detent on 200mm (8”)
reels and be sure to install spring pressure plate directl y under t ension nut.
3. Unfasten the wire end from the reel, but hold on it all the ti m e.
4. Straighten the wire end 20 cm out and cut the wire in the straightened location.
5. Open the pressure control level which then exposes the drive roll wire groove.
6. Thread the wire through the wire’s rear guide, over the roller making c ertain it aligns with
groove, feed 10 cm into the gun’s wire guide.
7. Close the feed gear and fasten it with the pressure control lever. Make sure that the wire
runs in the feed roll groove.
8. Adjust the compression pressure with the pressure control lever no higher than to the
middle of the scale. If the pressure is too high, it removes metal fragments from the wire
surface and may damage the wire. On the other hand, if the pressure is too low, the feed
gear slips and the wire does not run smoothly.
9. Make sure the gun nozzle and contact tip are removed.
Note
：When driving the wire into the gun, do not point the gun at yourself or others.
10. Press t he welding gun trigger to feed the wire into the gun. Once it extends out, reinstall
tip using wrench to tighten. Reinstall nozzle.
