Never simultaneously touch electrically "hot" parts of electrode holders connected to two
separate welders, because voltage between the two can be the total of the open circuit
When working above floor level, use a safety belt to protect yourself from a fall should
you get a shock.
In semi-automatic or automatic welding, welding wire, electrode reel, welding head,
nozzle or torch are also electrically hot

”.
Always be sure the work cable makes a good electrical connection with the metal being
welded. The connection should be as close as possible to the area being welded.
While the welder is electrically hot, do not insert your hand or any other object inside it.
WELDING ARC and ARC RAYS can burn.
Use a shield with proper filter and cover plates to protect your eyes from sparks and the
rays of the arc when welding or observing open arc welding. Skin should be protected
by clothing made from flame resistance material. Protect other nearby personnel with
suitable, non-flammable screening and/or warn them not to watch the arc nor expose
themselves to the arc rays or to hot spatter or metal.
When eyes are exposed to UV rays even for a short time, also called as Getting
“
Welder s Flash , it may cause burns in your eyes. Getting Welder s Flash may not be

noticed after hours of exposing, but it is too irritating as well as may cause transient
blindness. Normally getting welder s flash is a temporary situation, but exposing eyes to
'
UV rays for a long time and frequently may cause permanent damage on eyes. As a
protection measure besides not to watch arc rays, also using welding goggles having
proper filter is necessary.
As a rule, welding should start with a dark colored protective filter then should continue
with a lighter colored filter sufficient to see the area being welded providing that not to
fall under the minimum level. Welding masks protect head, face, ears and neck against
electric shock risk, heat, sparks and fire.
