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

use.

• Do not use an extension cord, as it causes the voltage to drop and affects

the performance of the welder. If needed, use an extension cord having a

minimum size of 12 gauge and maximum length of 25 feet.

• Use safety goggles and ear protection:

Wear safety glasses with side shields when operating the

welder and verify that others in the work area are also

wearing safety glasses. Safety glasses must conform to

American National Standards Institute (ANSI Z87.1)

requirements and must provide protection from flying

particles from the front and the sides.

Always wear ear protection to help prevent hearing damage.

Failure to comply may result in loss of hearing.

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.
