A Install and continue to maintain equipment according

to USA Standard C1, National Electric Code.

B Never allow live metal parts to touch bare skin or any

wet clothing. Use only dry gloves.

C When welding or cutting in a damp area, or when

standing on metal, make sure you are well in

-

sulated by wearing dry gloves, rubber soled

shoes, and by standing on a dry board or plat

-

form.

D Do not use worn or damaged welding or torch cables.

Do not overload the cables. Use well maintained

equipment.

E When not welding/cutting, turn equipment OFF. Ac

-

cidental grounding can cause overheating and

create a fire hazard. Do not coil or loop the ca

-

ble around parts of the body.

8020MAGNETICARCCONTROLLER

xii

F The ground cable should be connected to the work

piece as close to the work area as possible.

Grounds connected to building framework or

other locations remote to the work area reduce

efficiency and increase the potential hazard of

electric shock. Avoid the possibility of the weld

-

ing or cutting current passing through lifting

chains, crane cables or other electrical paths.

G Keep everything dry you might touch, including

clothing, the work area, welding gun, torch and

welding or cutting machines. Fix water leaks

immediately. Do not operate equipment stand

-

ing in water.

H Never use a cutting torch or welding gun which is

damaged or contains cracked housing.

I Refer to AWS-Z49.1 for grounding recommendations.

A Use a proper face shield fitted with the correct filter

(#10 or greater) and cover plates to protect

your eyes, face, neck and ears from the sparks

and rays of the cutting/welding arc when

cutting/welding or observing cutting/welding.

Warn bystanders not to watch the arc and not

to expose themselves to the cutting/welding

arc rays or to hot metal.

B Wear flameproof gauntlet-type gloves, a heavy

long-sleeve shirt, cuff-less trousers,

high-topped shoes, and a welding helmet or

cap (for hair protection) to protect the skin

from arc rays and hot sparks or hot metal.

C Protect other nearby personnel from arc rays and

hot sparks with a suitable non-flammable par

-

tition.

D Always wear safety glasses or goggles when in a

cutting or welding area. Use safety glasses with

side shields or goggles when chipping slag or

grinding. Chipped slag is hot and may travel a

considerable distance. Bystanders should also

wear safety glasses or goggles.

E Compressed gas cylinders are potentially dangerous,

refer to the suppliers for proper handling pro

-

cedures.

F Wear ear plugs or other ear protection devices when

operating cutting or welding equipment.

A Move all combustible materials well away from the

cutting area or completely cover materials

with a non-flammable covering. Combustible

materials include but are not limited to wood,

clothing, sawdust, gasoline, kerosene, paints,

solvents, natural gases, acetylene, propane,

and similar articles.

B Do not weld, cut or perform other hot work on used

barrels, drums, tanks or other containers until

they have been completely cleaned. There

must be no substances in the container which

might produce flammable or toxic vapors.

C For fire protection, have suitable extinguishing

equipment handy for instant use.

EXTENDEDPERIODOF TIME.

A At all times, provide adequate ventilation in the weld

ing and cutting area by either natural or me

-

chanical means. Do not weld or cut on

galvanized, zinc, lead, beryllium or cadmium

materials unless positive mechanical ventila

-

tion is provided to prevent inhaling fumes and

gases from these materials.

B Do not weld or cut in locations close to chlorinated

hydrocarbon vapors coming from degreasing

or spraying operations. The heat of arc rays

can react with solvent vapors to form phos

-

gene, a highly toxic gas, and other irritant

gases.

C If you develop momentary eye, nose or throat irrita

-

tion during welding or cutting, it is an indica

-

tion that the ventilation is not adequate. Stop

work and take the necessary steps to improve

ventilation in the welding or cutting area. Do

not continue to weld or cut if physical discom

fort persists.

8020MAGNETICARCCONTROLLER

xiii

D Use an air supplied respirator if ventilation is not

adequate to remove all fumes and gases.

E Beware of gas leaks. Welding or cutting gases con

-

taining argon are denser than air and will replace

air when used in confined spaces. Do not locate

gas cylinders in confined spaces. When not in

use, shut OFF the gas supply at its source.

Use lifting eyes to lift unit only, not running

gear, gas cylinders, or any other accessories.

Use equipment of adequate capacity to lift

units.

If using fork lifts to move units, be sure forks

are long enough to extend beyond opposite

side of the unit.

HOT PARTS
