RESISTANCE SPOT WELDING SAFETY PRECAUTIONS

WARNING

PROTECT YOURSELF AND OTHERS FROM POSSIBLE SERIOUS INJURY OR DEATH. KEEP CHILDREN

AWAY. PACEMAKER WEARERS KEEP AWAY UNTIL CONSULTING YOUR DOCTOR.

In resistance spot welding, as in most jobs, exposure to certain hazards occurs. Spot welding is safe when

precautions are taken. The safety information given below is only a summary of the more complete safety

information that will be found in the Safety Standards listed on the next page. Read and follow all Safety Standards.

HAVE ALL INSTALLATION, OPERATION, MAINTENANCE, AND REPAIR WORK PERFORMED ONLY BY

QUALIFIED PEOPLE.

SPOT WELDING can be hazardous.

RESISTANCE SPOT WELDING can

cause fire or explosion.

Sparks can fly off from the weld. The flying sparks, hot

workpiece, and hot equipment can cause fires and

burns.

1. Protect yourself and others from flying sparks and hot metal.

2. Do not spot weld where flying sparks can strike flammable

material.

3. Remove all flammables within 35 ft (10.7 m) of the weld. If this is

not possible, tightly cover them with approved covers.

4. Be alert that welding sparks can easily go through small cracks

and openings to adjacent areas.

5. Watch for fire, and keep a fire extinguisher nearby.

6. Do not spot weld on closed containers such as tanks or drums.

7. Do not weld where atmosphere may contain flammable dust,

gas, or liquid vapors (such as gasoline).

8. Remove any combustibles, such as a butane lighter or matches,

from your person before doing any welding.

9. After completion of work, inspect area to ensure it is free of

sparks, glowing embers, and flames.

10. Do not exceed the equipment rated capacity.

11. Use only correct fuses or circuit breakers. Do not oversize or

bypass them.

ELECTRIC SHOCK can kill.

Touching live electrical parts can cause fatal shocks

or severe burns. The input power circuit and machine

internal circuits are also live when power is on.

Incorrectly installed or improperly grounded

equipment is a hazard.

1. Do not touch live electrical parts.

2. Wear dry, hole-free insulating gloves and body protection.

3. Disconnect input power before installing or servicing this

equipment. Lockout/tagout input power according to OSHA 29

CFR 1910.147 (see Safety Standards).

4. Properly install and ground this equipment according to this

manual and national, state, and local codes.

5. Check and be sure that input power cord ground wire is properly

connected to ground terminal in disconnect box or that cord plug

is connected to a properly grounded receptacle outlet − always

double-check the supply ground before applying power.

6. When making input connections, attach the grounding conductor

first.

7. Keep cords dry, free of oil and grease, and protect from hot metal

and sparks.

8. Frequently inspect input power cord and ground conductor for

damage − replace immediately if damaged. Check ground

conductor for continuity.

9. Turn off all equipment when not in use.

10. For water-cooled equipment, check and repair or replace any

leaking hoses or fittings. Do not use any electrical equipment if

you are wet or in a wet area.

11. Use only well-maintained equipment. Repair or replace

damaged parts at once.

12. Wear a safety harness if working above floor level.

13. Keep all panels, covers, and guards securely in place.

SPARKS can cause injury.

Very often sparks fly off from the joint area.

1. Wear approved face shield or safety goggles with side shields.

2. Wear protective garments such as oil-free, flame-resistant

leather gloves, heavy shirt, cuffless trousers, high shoes, and a

cap. Synthetic material usually does not provide such protection.

3. Protect others in nearby areas by using approved

flame-resistant or noncombustible fire curtains or shields. Have

all nearby persons wear safety glasses with side shields.

HOT METAL can cause burns.

Wear gloves or allow cooling period before servicing

tongs or tips.

1. Always wear welding-type, insulated gloves when using this

equipment.

2. Do not touch workpiece, tips, or tongs with bare hands.

MOVING PARTS can cause injury.

The tong tips, tongs, and linkages move during

operation.

1. Keep away from moving parts.

2. Keep away from pinch points.

3. Do not put hands between tips.

4. Keep all guards and panels securely in place.

FUMES can be hazardous to your

health.

Coatings, cleaners, paints, and platings can produce

fumes when welded. Breathing these fumes can be

hazardous to your health.

1. Do not breathe the fumes.

2. If inside, ventilate the area and/or use exhaust at the weld to

remove fumes.

3. In confined spaces, use an approved air-supplied respirator.

4. Do not weld on metals, such as galvanized, lead, or cadmium

plated steel, unless the coating is removed from the weld area,

the area is well ventilated, or if necessary, while wearing an

air-supplied respirator. The coatings and any metals containing

these elements can give off toxic fumes if welded.

5. Read the Material Safety Data Sheets (MSDSs) and the

manufacturer’s instructions for metals, coatings, and cleaners.

EMF INFORMATION

The following is a quotation from the General Conclusions Section of

the U.S. Congress, Office of Technology Assessment, Biological

Effects of Power Frequency Electric & Magnetic Fields −

Background Paper, OTA-BP-E-53 (Washington, DC: U.S.

Government Printing Office, May 1989): “. . . there is now a very large

volume of scientific findings based on experiments at the cellular

level and from studies with animals and people which clearly

establish that low frequency magnetic fields can interact with, and

produce changes in, biological systems. While most of this work is

of very high quality, the results are complex. Current scientific

understanding does not yet allow us to interpret the evidence in a

single coherent framework. Even more frustrating, it does not yet

allow us to draw definite conclusions about questions of possible risk

or to offer clear science-based advice on strategies to minimize or

avoid potential risks.”

CAUTION

EXCEEDING DUTY CYCLE RATINGS will damage unit.

• Do not exceed 50% duty cycle.

warn7.1* 2/92

The duty cycle of a resistance spot welder is the percentage of a one minute period that a resistance spot welder can

be operated without causing overheating or damage to the unit. These resistance spot welders are rated at 50% duty

cycle, which means that they can be operated for thirty seconds out of every minute.

SECTION 3 − INSTALLATION

3-1. Tong And Tip Installation

WARNING

ELECTRIC SHOCK can kill.

• Do not touch live electrical parts.

• Turn Off unit, and disconnect input power cord plug from receptacle before inspecting or installing.

• Allow tongs and tips to cool before touching.

Keep tips dressed down to within a 1/8 in (3.2 mm) diameter or less for 1.5 kVA

models, and to within 5/32 in (4 mm) diameter or less for 2.5 kVA models (see

Section 5-3).

Be sure ends of tongs are clean and free of corrosion before installing.

3-2. Tong Pressure Adjustment

ELECTRIC SHOCK can kill.

• Do not touch live electrical parts.

• Turn Off unit, and disconnect input power cord plug

from receptacle before inspecting or installing.

• Allow tongs and tips to cool before touching.

EXCESSIVE TONG PRESSURE can

damage tips.

• Do not use tongs as a clamp or vice to hold

workpiece together.

If the two pieces of material to be welded do not make

good contact at the point of the intended weld, clamp

material to provide good contact between surfaces.

WARNING

Tong pressure is adjustable, and must be checked and/or set before operation.

Correct tong pressure is necessary to create a quality weld and to prevent damage

to tips.

Too much tong pressure causes the weld nugget to dimple and material to splash

out around the nugget area.

If tong pressure is too weak, parts are loose when the tongs are closed, severe

arcing occurs between workpieces, and no weld can be made.

To decrease tong pressure, loosen

the rear nut and turn the front nut up

to the pivot casting.

The farther down the screw is

turned, the farther the hand lever

to your health.

• Keep your head out of the fumes.

• Ventilate area, or use suction device at weld area.

• Read Material Safety Data Sheets (MSDSs) and

manufacturer’s instructions for metals, coatings,

and cleaners.

WELDING can cause fire or explosion.

• Do not weld near flammable material.

• Watch for fire; keep extinguisher nearby.

switch is closed (see Figure 4-2).

When the time set on the timer has

ended, or the start switch is re-

leased, weld output stops, and re-

sets for another weld cycle. A light
