2. ELECTRIC ARC (MIG, TIG) WELDING

Comply with precautions in 1 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, weldments are hot. The wise
operator avoids unnecessary risks and protects himself and others from accidents.

2A)  BURN PROTECTION

Comply with precautions in 2. The welding arc is intense and visibly bright. Its
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.

DON’T GET BURNED! COMPLY WITH PRECAUTIONS!

1) Protective clothing

Wear long sleeved clothing (particularly for gas shielded arc) in addition to
gloves, hat and shoes (2A). 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 collar to protect chest and neck and button
pockets to prevent entry of sparks.

2) Eye and head protection

Protect eyes from exposure to arc. NEVER look at an electric arc without
protection. Welding helmet or shield containing a filter plate shade no. 12 or
denser must be used when welding. Place over face before striking arc. Protect
filter plate with a clear cover plate. Cracked or broken helmet or shield should
NOT be worn; radiation  can pass through to cause burns. Cracked, broken,
or loose filter plates must be replaced IMMEDIATELY. Replace clear cover plate
when broken, pitted, or spattered. WE SUGGEST you wear flash goggles with
side shields under the helmet, to give some protection to the eyes should the
helmet not be lowered over the face before an arc is struck. Looking at an
arc momentarily with unprotected eyes (particularly a high intensity
gas-shielded arc) can cause a retinal burn that may leave a permanent dark
area in the field of vision. Before welding whilst wearing contact lenses, seek
advice from your optician.

3) Protection of nearby personnel

For production welding, a separate room or enclosed bay is best.
In open areas, surround the operation with low reflective, non- combustible
screens or panels. Allow for free air circulation, particularly at floor level. Provide
face shields for all persons who will be looking directly at the weld. Others
working in the area should wear flash goggles. Before starting to weld, make
sure that screen or bay doors are closed.
