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.”

To reduce magnetic fields in the workplace, use the following

procedures:

1. Keep cables close together by twisting or taping them.

2. Arrange cables to one side and away from the operator.

3. Do not coil or drape cables around the body.

4. Keep welding power source and cables as far away as practical.

5. Connect work clamp to workpiece as close to the weld as

possible.

About Pacemakers:

The above procedures are among those also normally

recommended for pacemaker wearers. Consult your doctor for

complete information.

WARNING

ENGINE EXHAUST GASES can kill.

• Do not breathe exhaust fumes.

• Use in open, well-ventilated areas, or vent exhaust

outside and away from building air intakes.

ENGINE EXHAUST SPARKS can cause

fire.

• Use only U.S. Forestry Department approved spark

arrestor and comply with all local, state, and federal

laws.

• A spark arrestor is mandatory in all National Forests

and in grass, brush, or forest covered lands in

California, Oregon, and Washington. Check with

state and local authorities in other areas.

• Properly maintain the spark arrestor.

• Stop engine and allow exhaust system to cool down

before servicing spark arrestor.

• Service spark arrestor away from flammables.

HOT ENGINE EXHAUST AND EXHAUST

PIPE can cause fires.

• Keep exhaust and pipe away from flammables.

FALLING EQUIPMENT can cause

serious personal injury and equipment

damage.

• Use lifting eye to lift unit only, NOT running gear, gas

cylinders, trailer, or any other heavy options,

accessories, or devices.

• Use equipment of adequate capacity to lift the unit.

TILTING OF TRAILER can result in

personal injury or equipment damage.

• Install unit properly on trailer (if applicable)

according to trailer manual.

WARNING

ENGINE FUEL can cause fire or

explosion.

• Stop engine before fueling.

• Do not fuel while smoking or near sparks or flames.

• Do not overfill tank; clean up any spilled fuel.

USE OF GASOLINE will damage engine.

• Do not use gasoline.

Lack of lubrication in gasoline damages injector pump

and injectors.

rwarn3.1* 3/93

rsb4.2 11/92 − ST-156 467-B

Check all fluids daily. Engine must

cable to + terminal.

For Direct Current Electrode Nega-

tive (DCEN), reverse cable con-

nections.

To prevent overheating and dam-

each polarity in case more than one

cable is needed to carry current to

a single arc (see Table 3-1). This

WARNING

IMPROPER HANDLING OR EXPOSURE TO ETHER

can seriously harm your health.

• Follow manufacturer’s safety instructions on cylinder.

INJECTING ETHER WHILE ENGINE IS RUNNING

can damage engine.

• Do not use Ether Starting Aid while engine is running.

After installing cylinder, wait at least 10 minutes before use to let ether

particles settle to prevent atomizer plugging.

rsb15.1 6/92A − ST-153 382

Stop engine. Open side door(s) to

locate ether starting aid.

Remove protective cover, and

clean nozzle and fitting area on

cylinder.

SECTION 4 − OPERATING THE WELDING GENERATOR

ELECTRIC SHOCK can kill.

• Do not touch live electrical parts.

• Always wear dry insulating gloves.

• Insulate yourself from work and ground.

• Stop engine before installing or servicing.

• Keep all panels and covers securely in place.

WELDING can cause fire or explosion.

• Do not weld near flammable material.

• Watch for fire; keep extinguisher nearby.

• Do not locate unit over combustible surfaces.

• Do not weld on closed containers.

• Allow work and equipment to cool before handling.

ARC RAYS can burn eyes and skin;

NOISE can damage hearing.

• Wear welding helmet with correct shade of filter.

• Wear correct eye, ear, and body protection.

FUMES AND GASES can be hazardous.

• Keep your head out of the fumes.

• Ventilate area, or use breathing device.

• Read Material Safety Data Sheets (MSDSs) and

manufacturer’s instructions for material used.

ENGINE EXHAUST GASES can kill.

• Do not breathe exhaust fumes.

• Use in open, well-ventilated areas, or vent exhaust

outside and away from any building air intakes.

ENGINE FUEL can cause fire or explo-

sion.

• Stop engine before fueling.

• Do not fuel while smoking or near sparks or flames.

• Do not overfill tank; clean up any spilled fuel.

MOVING PARTS can cause injury.

• Keep away from moving parts such as fans, belts,

and rotors.

• Keep all doors, panels, covers, and guards closed

and securely in place.

MAGNETIC FIELDS FROM HIGH CUR-

RENTS can affect pacemaker operation.

• Pacemaker wearers keep away.

• Wearers should consult their doctor before going

near any welding operations.

See Safety Precautions at beginning of manual for ba-

sic welding safety information.

1 Work Clamp

Connect work clamp to a clean,

paint-free location on workpiece, as

close to weld area as possible.

Use wire brush or sandpaper to

clean metal at weld joint area. Use

chipping hammer to remove slag

after welding.

Use constant current (CC) position

for SMAW and CAC-A.

Use constant voltage (CV) position

for wire feeding processes, GMAW,

SAW, and FCAW. When using CV

position, place Ampere Ranges

switch in CV position (see

Figure 4-5).

CAUTION

ARCING can damage switch.

• Do not change Ampere Ranges switch position while welding.

Arcing inside switch can damage contacts, causing switch to fail.
