ARC WELDING SAFETY PRECAUTIONS
ELECTRIC SHOCK
can
kill.
Touching
live electrical
parts
can cause
fatal shocks
or
severe
burns. The electrode and work circuit is
electrically
live whenever the
output
is
on.
The
input
power circuit and machine internal circuits
are
also
live when power is
on.
In
semiautomatic
or
automatic
wire
welding,
the
wire,
wire
reel,
drive roll
housing,
and all metal
parts
touching
the
welding
wire
are
electrically
live,
Incorrectly
installed
or
improperly
grounded equipment
is
a
hazard.
