SAFETY GUIDELINES
5
MIG 180 INVERTER WELDER 058-9306-4
DANGER!
Potential hazard that will result in serious injury or loss of life.
• Keep children or other personnel away from the work area while welding. Do
not allow children or persons with mental or physical disabilities to handle
the welder.
• Do not use the welder in the presence of flammable liquids or gases. Sparks
that are created during use may ignite gases.
• Always ensure that a fire extinguisher is available in an adequate distance
within the welding environment.
• Have the welder repaired by a qualified technician in accordance with local,
provincial and national codes.
• Do not repair or maintain the welder while the power is on.
• Do not use an ungrounded power source, as it might cause electrical shock
to the user.
• The welding process must conform to ANSI Z49.1; NFPA 51; OSHA 29 CFR,
part 1910, sub part Q; CSA W117.2; American Welding Society standard A6.0.
• Do not expose the welder to rain.
• Always disconnect the power supply when working on internal components.
• Do not touch the PC board without being properly grounded with a wrist
strap. Place the PC board in a static proof bag while shipping.
• Make sure harmful arc rays are shielded from view of other personnel.
• Do not operate the welder in humid, wet or poorly ventilated areas.
• Risk of electric shock: Do not touch electrical live parts or metal
components connected to the welding wire, as doing so may cause fatal
shock and severe burns. Secure the ground lead before welding. Poor ground
connection creates hazardous situation. Wear a dry protective apparel like a
coat, shirt, gloves, and insulated footwear.
SAFETY GUIDELINES
6
MIG 180 INVERTER WELDER 058-9306-4
• Risk of explosion: Keep high pressure shielding gas cylinder away from
welding or electrical circuits. Never expose cylinders to high heat, sparks,
open flames, mechanical shocks or arcs. Do not touch the cylinder with MIG
gun and do not weld on the cylinder. Use proper regulators, gas hoses and
fittings for the specific application. Use protective cylinder cap whenever
possible.
• Risk for breathing: Never directly inhale the emission of harmful fumes
during welding. Make sure the work area is clean, dry and ventilated. Use a
ventilation device to remove welding fumes from the work environment.
• Do not weld on coated materials like galvanized, cadmium plated or
contacting zinc, mercury or barium, as they emit harmful fumes that are
dangerous to breathe. If required, use a respirator with air supply or remove
coating from the material in the weld area.
• Do not weld near materials that will emit toxic fumes when heated. Vapours
from cleaners, sprays and degreasers can be highly toxic when heated.
• Risk of burns: Do not touch the welded materials with bare hands, as the
welded materials are hot and can cause severe burns. Do not touch MIG gun
nozzle or tip of the electrode holder after welding until it has been cooled.
• Wear garments that are oil-free with no pockets or cuffs that will collect
sparks.
• Risk of fire: Do not weld on containers or pipes that contain flammable,
gaseous or liquid combustibles. Welding creates sparks and heat that ignite
flammable and explosive materials. Remove all flammable materials within
35 feet of the welding arc or tightly cover the flammable materials with
fireproof covers. Ensure that flying sparks do not cause fires or explosions in
hidden areas, cracks or areas that are out of vision. Use a fire extinguisher in
the work area. Do not have any items that are combustible, such as lighters
or matches
• Connect the work lead to the weld area as close as possible to prevent any
unknown, unintended paths of electrical current from causing electrical
shock and fire hazards. To prevent any unintended arcs after welding, cut off
the excess wire that extends past the end of the nozzle more than ¼".
SAFETY GUIDELINES
7
MIG 180 INVERTER WELDER 058-9306-4
• Risk of UV and IR arc rays: Do not look at the welding arc without proper eye
protection, as the welding arc produces ultraviolet (UV) and infrared (IR) rays.
Use shields that adheres to ANSI Z87.1. For welders under 160 A output, use a
shade 10 lens; for above 160 A, use a shade 12 lens. Wear flame retardant
clothes, leather shirts, pants or shoes to cover the bare skin from the arc.
• Use appropriate shield to prevent other personnel from being affected by
harmful rays.
• Risk of electromagnetic fields: Electromagnetic field can damage electrical
and electronic devices like pacemakers and hearing aids. Make sure people
using pacemakers are away from your welding area when welding. Always
wrap the MIG gun and ground cable together.
WARNING!
Potential hazard that could result in serious injury or loss of life.
•
Do not allow unskilled or untrained individuals to install and operate this
welder.
• Keep hands and fingers away from moving parts such as drive roll or fan
while the welder is in use.
• Before operating the welder, check the insulation of the ground cable, power
cord, and welding cable for damage. Replace or repair the damaged
components before using the welder. Use only recommended parts for
replacement.
• Avoid contacting or touching welding wire, work piece, ground connection or
electrode from another welder.
• Do not drape cables over or around the body.
• Do not point the MIG gun toward yourself or other personnel.
• Consult a doctor before using the electric arc welder.
• Always have a secure stance while welding to prevent accident.
• Do not use this welder when you are tired or under influence of alcohol or
drugs.
• Connect the ground lead close to the work area to ensure proper ground
connection.
• Always secure the high pressure cylinder upright to a cart or stationary
object.

• Do not look into the valve of the high pressure cylinder when opening it.
SAFETY GUIDELINES
8
MIG 180 INVERTER WELDER 058-9306-4
Note: Recycle unwanted materials rather than disposing of as waste. Sort the tools, hoses, and
packaging in specific categories. Take them to the local recycling centre or dispose of in an
environmentally safe way.
CAUTION!
Potential hazard that may result in moderate injury or damage to
equipment.
• Do not operate the welder if the welding cables, electrode, MIG gun, wire or
wire feed system is wet. Do not immerse them in water. The welder and its
components must be completely dry before attempting to use the welder.
• Keep the welder in the OFF position when not in use.
• Do not wear watches, rings, bracelets, or loose clothing when using the
welder.
• Maintain a correct position while using the welder. Mount the welder on a
secure bench or cart to prevent it from tipping over or falling.
• Wear a full covered helmet with appropriate shade that conforms to
ANSI Z87.1 safety standard, proper gloves, and protective clothing such as
leather shirt, coat, pants, and insulated footwear to prevent the skin from
being exposed to hot metals, UV and IR rays while welding.
• Do not overheat or overuse the welder to prevent it from being heated. Allow
proper cooling time between duty cycles. Always use this welder in the rated
duty cycle to prevent excessive heat and failure.
• Ensure that all the components are clean and in good working condition before

MIG 180 INVERTER WELDER 058-9306-4
Voltage control (MIG mode)/Amperage control (stick mode)
This control is located on the upper front panel of the welder. It is used to adjust the welding voltage
when the MIG mode is engaged and to adjust the welding amperage when the stick mode is
engaged.
Output current indicator
This indicator is located on the upper front panel of the welder and glows when the welding unit is
providing enough power to weld.
Wire feed speed control
This control is located on the upper front panel of the welder and used to adjust the speed of the
wire being fed when in the MIG welding mode.
Polarity changing
For flux core welding (no shielding gas is
required) the MIG gun lead is connected to the
negative (“-”) terminal and the ground cable is
connected to the positive (“+”) terminal.
For MIG welding (solid wire) using shielding
gas, the MIG gun lead is connected to the
positive (“+”) terminal and the ground cable is
connected to the negative (“-”) terminal.

MIG 180 INVERTER WELDER 058-9306-4
Gas selection
Different materials require different shielding gas when MIG welding. Refer to the set-up chart inside
the wire drive compartment.
Mild steel: Use 75% Argon and 25% for reduced spatter and reduced penetration for thinner
materials. Use CO
2
for deeper penetration and increased spatter.
Note: Do not use argon gas concentrations higher than 75% on steel. The result will be extremely
poor penetration, porosity, and brittleness of weld.
Stainless steel: Use a mixed gas consisting of Helium, Argon, and CO
2
.
Aluminum or bronze: Use 100% Argon.
Electrode
The welding electrode is a rod coated with a layer of flux. During the process of welding, electrical
current flows between the electrode (rod) and the grounded metal work piece. The intense heat of
the arc between the rod and the grounded metal melts the electrode and the flux. The most popular
electrodes are mentioned below:
Torch travel:
Refers to the movement of the welding torch along the weld joint.
Travel direction:
Refers to the direction of the torch moving along the weld joint in relation to the weld puddle.
Travel speed:
The rate at which the torch is being moved along the weld joint.
