1. SAFETY INFORMATION
The following safety alert symbols and signal words are used throughout this manual to
identify various hazards and special instructions.
A W ARNING WARNING gives information regarding possible personal
injury or loss of life. |
A CAUTION CAUTION refers to minor personal injury or possible
equipment damage.
2. ARC WELDING SAFETY PRECAUTIONS
A WARNING
“ARC WELDING can be hazardous.
€ PROTECT YOURSELF AND OTHERS FROM POSSIBLE SERIOUS INJURY OR
DEATH. |
Be sure to:
- Keep children away.
- Keep pacemaker wearers away until consulting a doctor.
€ Read and understand the summarized safety information given below and the original]
principal information that will be found in the PRINCIPAL SAFETY
STANDARDS.
€ Have only trained and experienced persons perform installation, operation, and
maintenance of this equipment.
$ Use only well maintained equipment. Repair or replace damaged parts at once.
| ARC WELDING is safe when precautions are taken.

ELECTRIC SHOCK can kill.
W
Touching live electrical parts can cause fatal shocks or severe burns. The electrode and work
circuits are electrically live whenever the output 1s on. The power line and internal circuits of
this equipment are also live when the line disconnect switch is on, When arc welding all
metal components in the torch and work circuits are electrically live.
1. Do not touch hve electrical parts.
2. Wear dry insulating gloves and other body protection that are free of holes.
3. Insulate yourself from work and ground using dry insulating mats or covers.
4. Be sure to turn off the line disconnect switch before installing, changing torch parts or
maintaining this equipment.
Properly install and ground this equipment according to its Owner’s Manual and
national, state, and local codes.
6. Keep all panels and covers of this equipment securely in place.
7. Do not use worn, damaged, undersized, or poorly spliced cables.
8. Do not touch electrode and any metal object if POWER switch is ON.
9.

Do not wrap cables around your body.
Q. Turn off POWER switch when not in use.

NX METAL can cause injury. NOISE can damage hearing.
vs
"os
Arc rays from the welding process produce intense heat and strong ultraviolet rays that can
burn eyes and skin.
Noise from some arc welding can damage hearing.
1. Wear face shield with a proper shade of filter ( See ANSI 7 49.1 listed in PRINCIPAL
SAFETY STANDARDS) to protect your face and eyes when welding or watching a
welder work.
2. Wear approved safety goggles. Side shields recommended.
3. Use protective screens or barriers to protect others from flash and glare: warn others not
to look at the arc. |
4. Wear protective clothing made from durable, flame-resistant material (Wool and leather)
and foot protection. |
5. Use approved earplugs or earmuffs if noise level is high.
Chipping and grinding can cause flying metal. As welds cool, they can throw off slag.
6. Wear approved face shield or safety goggles. Side shields recommended.
7. Wear proper body protection to protect skin |

WELDING can cause fire and explosion.
Sparks and spatter fly off from the welding arc. The flying sparks and hot metal, spatter, hot base
metal, and hot equipment can cause fire and explosion. Accidental contact of electrode or
welding wire to metal object can cause sparks, overheating, or fire.

Protect yourself and others from flying sparks and hot metals.
Do not weld where flying sparks can strike flammable material.
Remove all flammables within 10m (35£t.) of the welding arc. If this is not possible, tightly,
cover them with approved covers.
Be alert that welding sparks and hot metals from welding can easily pass through cracks and
openings into adjacent areas.
Watch for fire, and keep a fire extinguisher nearby.
Be aware that welding on a ceiling, floor, bulkhead, or partition can ignite a hidden fire.
Do not weld on closed containers such as tanks or drums.
Connect base metal side cable as close to the welding area as possible to prevent the welding
current from traveling along unknown paths and causing electric shock and fire hazards.
Remove stick electrode from holder or cut off welding wire at contact tip when not in use.
Do not use the welding power source for other than arc welding.
Wear oil-free protective garments such as leather gloves, a heavy shirt, cuffiess trousers,
boots, and a cap.
A loose cable connection can cause sparks and excessive heating.
Tighten all cable connections.
FUMES AND GASES can be hazardous to your health.
Arc welding produce fumes and gases. Breathing these fumes and gases can be hazardous to
your health.
1. Keep your head out of the fumes. Do not breathe the fumes.
2. Ventilate the area and / or use exhaust at the arc to remove welding fumes and gases.
3. If ventilation is poor, use an approved air-supplied respirator.
4. Read the Material Safety Data Sheets (MSDS) and the manufacturer’s instructions on
metals, consumables, coatings, and cleaners. |
5. Do not weld or cut in locations near degreasing, cleaning, or spraying operations.
The heat and rays of the arc can react with vapors to form highly toxic and irritating gases.
6. Work in a confined space only if it is well ventilated, or while wearing an air-supplied
respirator. Shielding gases used for welding can displace air causing injury or death.
Be sure the breathing air 1s safe. |
No. U4283
P. 5/21
CYLINDER can explode if damaged.
A shielding gas cylinder contains high-pressure gas. If damaged, a cylinder can explode.
Since gas cylinders are normally part of the welding process, be sure to treat them carefully.
1.
2.
3.
hd
>
Use only correct shielding gas cylinders, regulators, hoses, and fittings designed for the
specific application; maintain them in good condition.
Protect compressed gas cylinders from excessive heat, mechanical shock, and arcs.
Keep the cylinder upright and securely chained fo a stationary support or a rack to prevent
falling or tipping.
Keep cylinders away from any welding or other electrical circuit.
Never touch cylinder with welding electrode.
Read and follow instructions on compressed gas cylinders, associated equipment, and the
CGA publication P-1 listed in PRINCIPAL SAFETY STANDARDS. |
Turn face away from valve outlet when opening cylinder valve.
Keep protective cap in place over valve except when gas cylinder is in use or connected for
use.
Rotating parts may cause Injuries. Be sure to observe the following.
If hands, fingers, hair or clothes are put near the fan’s rotating parts or wire feeder’s feed roll,
injuries may occur.
1.
2.
Do not use this equipment if the case and the cover are removed.
When the case is removed for maintenance/inspection and repair, certified or experienced
operators must perform the work. Erect a fence, etc. around this equipment to keep others
away from it.
Do not put hands, fingers, hair or clothes near the rotating fans or wire feed roll.
No. U4283
P. 6/21
ARC WELDING work areas are potentially hazardous.
FALLING or MOVING machine can cause serious injury.
® Use both eyebolts, if installed, to lift the welding power source.
Ф Put the welding power source and wire feeder solidly on a flat surface.
Ф Do not pull the welding power source across a floor laid with cables and hoses.
Ф Do not put wire feeder on the welding power source.
€ Do not put the welding power source and wire feeder where they will pit or fall.
WELDING WIRE can cause puncture wounds.
€ Do not press gun trigger until instructed to do so.
|* Do not point gun toward any part of the body, other people, or any metal when threading
welding wire. |
