Safety Precautions

WARNING:

Before performing any installation or operating

procedures read and follow the safety precautions listed below.
Failure to observe these safety precautions can result in
personal injury or death.

Personal Protection:

Skin and eye burns resulting from body

exposure to the electric-arc welding rays or hot metal can be
more severe than sunburn:

a.  Use a proper face shield fitted with correct filter and cover 

plates to protect your eyes, face, neck and ears from sparks 
and rays of the cutting arc when cutting or observing cutting.
WARN bystanders not to watch the arc or expose themselves
to the welding-arc rays or hot metal.

b. Wear flameproof gauntlet-type gloves, heavy long-sleeve 

shirt, cuffless trousers, high topped shoes and a welding 
helmet or cap for hair protection to protect the skin from arc 
rays and hot sparks or metal.  A flameproof apron may also 
be desirable as protection against radiated heat and sparks.

c. Hot sparks or metal can lodge in rolled up sleeves, trouser 

cuffs or pockets.  Sleeves and collars should be buttoned, and
pockets eliminated from the front of the clothing.  Protect 
other nearby personnel from arc rays and sparks with a 
suitable non-flammable partition.

d. Always wear safety glasses or goggles within the cutting 

area.  Use safety glasses with side shields or goggles when 
chipping slag or grinding.  Chipped slag is hot and can travel 
considerable distances.  Bystanders should also wear safety 
glasses or goggles. 

Fire Protection:

Hot slag, or sparks, can cause serious fires

when in contact with combustible solids, liquids or gases:

a. Remove all combustible materials well away from the 

welding area or completely cover the materials with a non-
flammable covering.  Such combustible materials include 
wood, clothing, sawdust, gasoline, kerosene, paints, solvents,
natural gas, acetylene, propane and similar combustible 
articles.
