3B) TOXIC FUME PREVENTION

Comply with precautions in 2B. Generator engine exhaust must be vented to

the outside air. Carbon monoxide can kill.

3C) FIRE AND EXPLOSION PREVENTION

Comply with precautions in 2C. Equipment’s rated capacity. Do not overload arc

welding equipment. It may overheat cables and cause a fire. Loose cable

connections may overheat or flash and cause a fire. Never strike an arc on a cylinder

or other pressure vessel. It creates a brittle area that can cause a violent rupture or

lead to such a rupture later under rough handling.

3D) SHOCK PREVENTION

Exposed live conductors or other bare metal in the welding circuit, or in

unearthed, electrically-LIVE equipment can fatally shock a person whose body

becomes a conductor. DO NOT STAND, SIT, LIE, LEAN ON, OR TOUCH a wet

surface when welding, without suitable protection.

3E) PROTECTION FOR WEARERS OF ELECTRONIC LIFE SUPPT DEVICES (PACEMAKERS)

Magnetic fields from high currents can affect pacemaker operation. Persons wearing

electronic life support equipment (pacemaker) should consult with their doctor

before going near arc welding, gouging, or spot welding operations.

3F) TO PROTECT AGAINST SHOCK:

Keep body and clothing dry. Never work in damp area without adequate

insulation against electrical shock. Stay on a dry duckboard, or rubber mat

when dampness or sweat can not be avoided. Sweat, sea water, or moisture

between body and an electrically LIVE part - or earthed metal - reduces the

body surface electrical resistance, enabling dangerous and possibly lethal

currents to flow through the body.

1) Earthing the equipment

When arc welding equipment is earthed according to the National

Electrical Code, and the workpiece is earthed, a voltage may exist

between the electrode and any conducting object.

Examples of conducting objects include, but are not limited to, buildings,

electrical tools, work benches, welding power source cases, workpieces,

etc. Never touch the electrode and any metal object unless the welding

power source is off. When installing, connect the frames of each unit such

as welding power source, control, work table, and water circulator to the

building earth.

Conductors must be adequate to carry earth currents safely. Equipment

made electrically LIVE by stray current may shock, possibly fatally. Do NOT

EARTH to electrical conduit, or to a pipe carrying ANY gas or a flammable

liquid such as oil or fuel.
