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.

PREPARATION OF THE WORKING AREA

The working area must be sufficiently spacious, not humid, and well-ventilated as to

avoid any fumes which develop from the welding process and from incidental material

adhering to the pieces to be welded (oils, paints, tars...) which may cause danger to

the operator.

Avoid welding tanks which may contain flammable residuals.

ELECTRIC ARC WELDING

Comply with precautions in above and this section. Arc welding, properly done, is a

safe process but a careless operator invites trouble. The equipment carries high

currents at significant voltages. The arc is very bright and hot. Sparks fly, fumes rise,

ultraviolet and infrared energy radiates and work pieces are hot. The wise operator

avoids unnecessary risks and protects himself and others from accidents.

BURN PROTECTION

The welding arc is intense and visibly bright. It’s radiation can damage eyes,

penetrate lightweight clothing, reflect from light coloured surfaces and burn the skin

and eyes. Skin burns resemble acute sunburn, those from gas - shielded arcs are

more severe and painful.

PROTECTIVE CLOTHING (PPE) MUST BE WORN

Wear long sleeved clothing (particularly for gas shielded arc) in addition to gloves,

apron and strong shoes. As necessary, use additional protective clothing such as

leather jacket or sleeves, flameproof apron, and fire-resistant leggings. Avoid outer

garments of untreated cotton. Bare skin protection: Wear dark substantial clothing,

Button collars closed to protect the chest and neck and button any pockets to prevent

entry of sparks.

WARNING: ELECTRIC SHOCK CAN BE FATAL. A PERSON QUALIFIED

IN FIRST AID SHOULD ALWAYS BE PRESENT IN THE WORKING

AREA. IF PERSON IS UNCONSCIOUS AND ELECTRIC SHOCK IS

SUSPECTED, DO NOT TOUCH THE PERSON IF HE OR SHE IS IN

CONTACT WITH THE WELDER OR CABLES. DISCONNECT THE

WELDER FROM THE POWER SOURCE AND THEN USE FIRST AID. DRY

WOOD OR OTHER INSULATING MATERIAL CAN BE USED TO MOVE

CABLES, IF NECESSARY, AWAY FROM THE PERSON.
