Fire & Explosion Prevention
Do not exceed the equipment’s rated capacity or overload the 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 rupture or lead to such a rupture later under rough handling.
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.
Protection of Wearers of Electronic Life Supoport 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 operations.
Protection Against Shock
Keep body and clothing dry. Never work in damp area without adequate insulation against electric
shock. Stay on a dry duckboard or rubber mat when dampness or sweat cannot 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.
Earthing the Equipment
When arc welding equipment is earthed according to the National Electrical Code, and the work
is also 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.
Electrode Holders
Fully insulated electrode holders should be used. Do NOT use holders with protruding screws or
with any form of damage.
Connectors
Fully insulated lock-type connectors should be used to join welding cable.
