General information
The electric arc may be described as a
source of bright light and strong heat;
!"#$&&'*+9<9"*=*$&>$$?>>*!&!&'*
gas atmosphere which surrounds the
electrode and the workpiece determines
the radiation of electromagnetic waves
that can be perceived as light and/or
heat depending on their wave length. At
an unperceivable level, the arc also pro-
duces ultra-violet and infra-red light; io-
nizing rays have never been noted. The
heat produced by the arc is used in the
welding process to melt and join metal
parts. The necessary electric current is
supplied by special equipment common-
ly called welding machine.
