PRECAUTIONS AND SAFE USE
Welding may result in injury to you and others, so please
implement proper protections and precautions when welding.
Electric shock-may result in serious injury or
even death!
Ensure devices are properly grounded.
Do not touch live parts with naked skin, wet
gloves or wet clothes.
Be sure you are insulated from the ground and
workpiece.
Confirm the safety of your working position.
Smoke may be harmful to your health!
Keep your head away from fumes and smoke
to avoid inhalation of waste gas while welding.
When welding, keep the working environment
well-ventilated with exhaust or ventilation
equipment.
MIG and ARC radiation may hurt your eyes
and burn your skin!
Use a proper welding mask and wear
protective clothing to protect your eyes and
body.
Ensure onlookers have a proper mask or
curtain to avoid injury.
Improper use and operation may result in fire
or explosion.
Welding sparks may cause fires, please
ensure there are no flammables near the
welding are and pay attention to fire safety.
Ensure there is a fire extinguisher nearby, and
make sure someone has been trained to
operate the fire extinguisher.
Do not weld in a closed unventilated container.
Do not use this machine for pipe thawing.
Hot workpieces can cause severe scalds or
burns.
Do not touch the workpiece(s) with bare
hands.
If continuously working, periodically cool the
welding torch to avoid overheating the tip.

Excessive noise can be harmful to people’s
hearing.
Wear proper hearing protection when welding.
Ensure onlookers have a proper hearing
protection or distance to avoid injury.
Magnetic field can impair cardiac pacemaker
operation.
People with a cardiac pacemaker should
consult their physician prior to attempting to
use welding equipment.
Moving parts may injure your body.
Please keep away from moving parts (like
fan).
Each door, panel, cover, baffle plate, and
protective device the like should be closed and
located correctly.
Seek professional support with operating
issues.
When an issue arises with the installation and
operation or the unit, please refer to the
operating manual before attempting repairs.
If the issue persists, or you still cannot solve
the problem, please contact the dealer to
obtain professional support.
Working Environment
Prior to welding, properly inspect the work area for potential
hazards before starting any welding operations.
1) Welding should be carried out in a dry environment with
humidity below 90%.
2) The temperature of the work area should be between 14⁰F
and 104⁰F.
3) Avoid welding in sunlight and rain. Keep everything dry at
all times.
4) Avoid welding in dusty areas or environment with corrosive
chemical gas.
5) MIG and ARC welding should be operated in an
environment without strong airflow.
6) Weld in a well-ventilated area or use proper ventilation
systems to remove harmful fumes and gases.

Safety Tips and Recommendations
This unit is equipped with an over-current/over-voltage/over-
heating protection circuit. When the supplied voltage, output
current or inner temperature exceeds these limits, the unit will
stop automatically. Please check those conditions prior to
restarting. WARNING: excessive use of the unit with these
conditions will lead to welder damage.
1. Ventilation
1.1. This welder will create powerful electrical currents that
require the unit to have constant cooling.
1.2. The internal fans are critical to ensuring proper and
effective cooling of the machine.
1.3. The operator must ensure that the louvers are
uncovered and unblocked for proper airflow.
1.4. The minimum distance between the unit and nearby
objects should be 76 inches.
1.5. Good ventilation is of critical importance for optimum
performance and longer lifespan of the unit.
2. Overload Operation
2.1. Remember to operate the welder within the allowable
duty cycle (refer to the corresponding duty cycle).
2.2. Ensure that the welding current does not exceed the
max load current.
2.3. Overload could obviously shorten the machine's
lifespan, or even damage the machine.
3. Exceeding Recommended Voltage
3.1. Verify the power supply voltage range of the unit, please
refer to “Technical Parameters” table.
3.2. This unit is equipped with automatic voltage
compensation, which enables it to maintain a voltage
range within the allowable supply ranges.
3.3. Power supply voltage that exceeds the recommended
levels may lead to damaging the components of the unit.

Safety Tips and Recommendations
4. Fault/Halt Indicator
4.1. A sudden halt may occur and the red indicator on the
front panel is lit.
4.2. The welder has exceeded the standard duty cycle which
triggers temperature alert due to overheating.
4.3. Should this occur, halt the welding operations and allow
the unit to cool down. Do not turn off the power and keep
the cooling fan operating to reduce the unit temperature.
4.4. Welding can be resumed after the unit temperature falls
back to the standard operating range and the red
indicator is off.

MIG-130S MIG Welding
System - User Guide
Welding Fundamentals
Welding is a relatively simple process for bonding two pieces of
metal together. As an example, soldering two wires together is
the same concept. To connect the wires, we use heat to melt
solder onto the wires to create the connection and a permanent
bond and circuit.
The welding process utilizes a very strong electrical current that
creates enormous heat that literally melts the two pieces
together, and a consumable rod (ARC Welder) or wire (MIG
Welder) is melted into the joint and creates a strong metallic
bond between the two pieces.
The MIG-130S is a MIG welder that uses a consumable wire that
is fed through to the welding head. This unit is an easy-to-use
MIG welder suitable for hobbyists and even professionals.
There is a slight learning curve and experimentation as to the
welding voltage and wire feed rate. Once you have that dialed in,
you typically do not need to change it unless you change the
diameter of the welding wire.
The MIG-130S works optimally with a steel wire of 0.8mm
diameter. Optionally, you can use 0.6mm, 0.9mm and 1.0mm of
either solid wire or cored wire. However, you will need to adjust
the welding voltage and feed rate for each wire diameter used.

OPERATING YOUR WELDER
At this point, you can now begin your welding project!
1. Turn the Welding Main Power Switch to the ON position.
2. The unit will “spin up” and verify all the indicator lights and
displays are working correctly.
3. Reminder: after reloading the wire coil, you will need to feed
the wire through the cable until it protrudes beyond the head.
4. Typically, 1-1/2” is recommended as a basic starting length.
Starting Up – General Settings and First Time Setup
1. Use 1 amp per .001 in (0.0025 cm) of metal thickness as a
general rule. For example, if you’re welding steel that is
.125” (0.32 cm) thick, set the amp dial to 125 amps.
2. Note: that you might find you need to adjust the amperage
after you start welding as different types of metals may need
a slightly higher or lower amperages.
3. Increase the wire size for higher amp ranges:
3.1. .023” (0.58 mm) wire for 30-120 amps.
3.2. .030” (0.76 mm) wire for 40-145 amps.
3.3. .035” (0.89 mm) wire for 50-180 amps.
3.4. .045” (1.1 mm) wire for 75-250 amps.
4. Select the starting wire feed speed based on the amps
you’re using. Multiply by 1” per amp for .045” wire, 1.6” per
amp for .035” wire, 2” per amp for .030” wire, and 3.5” per
amp for .023” wire. Then adjust accordingly as you weld.
Adjusting Wire Speed
As you begin welding, if you find the wire is pushing you away
from your pieces, reduce the wire speed. And conversely, if you
are being pulled too close, increase the speed.

Recommended Maintenance
1) After each use, remove welding spatters from the welding
head tip and check the condition of the parts. Check for
dents, cracks and any imperfections. Replace damaged
parts immediately as they will impact performance and user
safety!
2) Inspect the insulating tips of the welding head for any
damage. Replace damaged parts immediately as they will
impact performance and user safety!
3) Verify that the welding head cable and grounding cables are
properly and securely attached to the main unit.
4) Inspect the power supply cable for any damage and replace
