SAFETY PRECAUTIONS

1. Be sure the power source frame (chassis) is

connected to the ground system of the input

power.

2. Connect the workpiece to a good electrical

ground.

3. Connect the work cable to the workpiece. A poor

or missing connection can expose you or others

to a fatal shock.

4. Use well-maintained equipment. Replace worn

or damaged cables.

5. Keep everything dry, including clothing, work

area, cables, torch/electrode holder, and power

source.

6. Make sure that all parts of your body are insulated

from work and from ground.

7. Do not stand directly on metal or the earth while

working in tight quarters or a damp area; stand

on dry boards or an insulating platform and wear

rubber-soled shoes.

8. Put on dry, hole-free gloves before turning on the

power.

9. Turn off the power before removing your

gloves.

10. Refer to ANSI/ASC Standard Z49.1 (listed on

next page) for specic grounding recommenda-

tions. Do not mistake the work lead for a ground

cable.

ELECTRIC AND MAGNETIC FIELDS

— May be dangerous. Electric cur-

rent owing through any conduc-

tor causes localized Electric and Magnetic Fields

(EMF). Welding and cutting current creates EMF

around welding cables and welding machines.

Therefore:

1. Welders having pacemakers should consult their

physician before welding. EMF may interfere with

some pacemakers.

2. Exposure to EMF may have other health eects

which are unknown.

3. Welders should use the following procedures to

minimize exposure to EMF:

A. Route the electrode and work cables together.

Secure them with tape when possible.

B. Never coil the torch or work cable around your

body.

C. Do not place your body between the torch and

work cables. Route cables on the same side of

your body.

D. Connect the work cable to the workpiece as close

as possible to the area being welded.

E. Keep welding power source and cables as far

away from your body as possible.

FUMES AND GASES -- Fumes and

gases, can cause discomfort or

harm, particularly in confined

spaces. Do not breathe fumes and

gases. Shielding gases can cause

asphyxiation. Therefore:

1. Always provide adequate ventilation in the work

area by natural or mechanical means. Do not weld,

cut, or gouge on materials such as galvanized

steel, stainless steel, copper, zinc, lead, beryllium,

or cadmium unless positive mechanical ventila-

tion is provided. Do not breathe fumes from these

materials.

2. Do not operate near degreasing and spraying opera-

tions. The heat or arc rays can react with chlorinated

hydrocarbon vapors to form phosgene, a highly

toxic gas, and other irritant gases.

3. If you develop momentary eye, nose, or throat

irritation while operating, this is an indication

that ventilation is not adequate. Stop work and

take necessary steps to improve ventilation in the

work area. Do not continue to operate if physical

discomfort persists.

4. Refer to ANSI/ASC Standard Z49.1 (see listing below)

for specic ventilation recommendations.
