1.0 Recommended Safety Precautions
The above safety warning signs indicate the risk of personal
injury or even death. IMPORTANT! Hot or moving parts can
cause serious injury and electric shock can kill. Use the
following MIG220 AC/DC operation guidelines to insure your
own personal safety and for those in the immediate vicinity
of your work area.
1.2 Safety Precautions Preface
• The following are explanations of dangers present while
operating the machine. Please remind yourself and others of
these dangers.
• Only people who are trained professionally can install,
debug, operate, maintain and repair the equipment.
• NEVER TOUCH electrical parts
• Use dry, hole-free gloves and other protective safety gear
• Protect yourself from work and ground using dry
insulation. Make sure inulation is sufficiently covering
the working area.
• Use caution when working in confined spaces, in wet
environments or where falling is a risk
CLOTHING:
Suitable clothing must be worn to prevent excessive skin
exposure to UV radiation, sparks and molten metal. Flame-
proof, loose fitting cotton clothing buttoned to the neck,
protective leather gloves, spats, apron and steel toe safety
boots are also highly recommended. In addition, use a
helmet with the recommended shade lens for amperage
listed in the shade chart below.
FUMES AND GASES CAN BE DANGEROUS:
• Welding may produce fumes and gases hazardous to
health. Avoid breathing these fumes and gases. When
welding, keep your head out of the fume. Use enough
ventilation and/or exhaust at the arc to keep fumes and
gases away from the breathing zone. When welding with
electrodes which require special ventilation such as stainless
or hard facing or on lead or cadmium plated steel and other
metals or coatings which produce highly 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.
• 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.
• Read and understand the manufacturer’s instructions for
this equipment and the consumables to be used, including
the material safety data sheet and follow your employer’s
safety practices.
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.
Less than 150 amps
150 to 250 amps

ROTATING PARTS MAY BE DANGEOUS:
• 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.
ELECTRIC AND MAGNETIC FIELDS:
Electric current flowing through any conductor causes
localized Electric and Magnetic Fields (EMF). The discussion
on the effect of EMF is ongoing all around the world. Until
now, no material evidences show that EMF may have effects
on health. However, the research on damage of EMF is still
ongoing. Before any conclusions are made, we should
minimize exposure to EMF as much as possible.
In order to minimize EMF, we should use the following
procedures:
• Route the electrode and work cables together – Secure
them with tape when possible.
• All cables should be put away and far from the operator.
• Never coil the power cable around your body.
• Make sure the welding machine and power cable are as
far away from the operator as possible.
• Connect the work cable to the workpiece as close as
possible to the area being welded.
• People with heart pacemakers should stay away from the
welding area.
The equipment complies with electromagnetic compatibility
on the class A which is intended for users in any locations
other than residential locations where the electrical power is
provided by public low-voltage supply system.
• 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-flam-
mable screening and /or warn them not to watch the arc nor
expose themselves to the arc rays or to hot spatter or metal.
WELDING SPARKS CAN CAUSE FIRE OR EXPLOSION.
• Remove fire hazards from the welding area. If this is not
possible, cover them to prevent the welding sparks from
starting a fire. Remember that welding sparks and hot
materials from welding can easily go through small cracks
and openings to adjacent areas. Avoid welding near hydrau-
lic lines. Have a fire extinguisher readily available.
• Where compressed gases are to be used at the job site,
special precautions should be used to prevent hazardous
situations.
• When not welding, make certain 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 “cleaned”.
• Vent hollow castings or containers before heating, cutting
or welding. They may explode.
• Connect the work cable to the work as close to the
welding area as practical. Work cables connected to the
building framework or other locations away from the
welding area increase the possibility of the welding current
passing through lifting chains, crane cables or other alter-
nate circuits. This can create fire hazards or overheat lifting
chains or cables until they fail.

1.3 Electrical Shock
• Never touch ‘live’ electrical parts
• Earth clamp all work materials
• Never work in wet or damp environments
Avoid electric shock by:
• Wearing dry, insulated boots
• Using dry, leather gloves
• Never change electrodes with bare hands or wet gloves
• Never cool electrode holders in water
• Work on a dry, insulated floor where possible
• Never hold the electrode or holder under your arm
1.4 User Responsibilities
• Read the Instructional Manual prior to using your
MIG220 AC/DC
• Unauthorised repairs to this equipment may endanger
the technician and operator and will void your Warranty.
Only qualified personnel should perform repairs
• Always disconnect mains power before investigating
equipment malfunctions
• Replace broken, damaged, missing or worn parts & hoses
immediately.
• Equipment should be cleaned & serviced periodically

The working principle of the MIG220 AC/DC welder is shown as the following figure.
Single phase work frequency AC 220V (50 Hz) is rectified into DC (380V), then is converted to medium frequency AC (about
44KHz) by inverter device (IGBT), after reducing voltage by medium transformer (the main transformer) and rectified by
medium frequency rectifier (fast recovery diodes), and is outputted by inductance filtering. The circuit adopts current and
voltage feedback control technology to ensure current/voltage output stability. The welding current parameter can also be
adjusted continuously to meet welding requirements.

3.2 Duty cycle & Over heating
The letter “X” stands for duty cycle, which is defined as the
proportion of the time that a machine can work continuously
within a certain time (10 minutes).
The rated duty cycle means the proportion of the time that a
machine can work continuously within 10 minutes when it outputs
the rated welding current.
The relation between the duty cycle “X” and the output welding
current “I” is shown as the right figure.
If the welder overheats, the IGBT over-heat protection unit inside
it will output an instruction to cut the output welding current, and
will light up the over-heat pilot lamp on the front panel. In the
event this occurs, the machine should be left to cool for 15
minutes. When operating the machine again, the welding output
current or the duty cycle should be reduced.

3.3 Movement and Placement
Please take care for the welder when moving it, and do not let it slope.
It also can be moved by the handle on the top of the welder. Place the welder well when moving it to the right position. When the machine
gets to the destination, it needs to be stabilized to avoid gliding.
When using a forklift, its arm length must be long enough to reach the outside so as to ensure lifting safely.
The movement may result in potential danger or substantive hazard, so please make sure that the machine is in a safe position before using
it.
3.4 Power supply input connection
The MIG220 AC/DC welding machines power supply connects to 220V.
When the power supply voltage is over/under the safe work voltage, the over voltage or under voltage protection inside the welder will
trigger, turning the alarm light on and cutting the current output off.
If the power supply voltage continually goes beyond the safe work voltage range, it will shorten the machines life-span.
The below measures can be used:
• Change the power supply input net - connect the welder with the stable power supply voltage of the distributor
• Induce the machines current power supply at the same time
• Set the voltage stabilization device in the front of the power cable input

Introduction:
Short circuit protection function:
1. TIG /DC/LIFT：If the tungesten electrode touches the workpiece when welding, the current will drop to 30A,
which can reduce tungsten spoilage，prolonging the life of the tungsten electrode，and prevent tungsten clipping.
2.TIG /DC/HF：If the tungesten electrode touches the workpiece when welding, the current will drop to 0 within 1s,
which can reduce tungsten spoilage，prolonging the life of the tungsten electrode，and prevent tungsten clipping.
3.MMA operation：if the electrode touches workpiece over two seconds, the welding current will drop to the 0
automatically to protect the electrode.
Prevent arc-break function：TIG operation，Avoid arc-break with special means, even if arc-break occurs the HF will
keep the arc stable.

Notices:
•Check the condition of welding and connection units first, otherwise there may be malfunctions such as ignition
sparks, gas leakages, loss of control and so on.
•Check whether there is enough Argon gas in the shield gas cylinder, you can test the electromagnetic gas
valve via the switch on the front panel.
• Do not let the torch aim at your hand or other parts of your body. When you press the torch switch, the arc is ignited with
a high-frequency, high-voltage spark and the ignition spark can cause interferences in equipment.
• The flow rate is set according to the welding power used in the job. Turn the regulation screw to adjust the gas
flow which is shown on the gas hose pressure meter or the gas bottle pressure meter.
• The spark ignition works better if you keep the 3mm distance from the workpiece to the tungsten electrode during the ignition.
