Arc
Welding
Power Source
in
welding
power
source
Owners Manual for basic
welding safety
information.
1.
Be
sure
that
proper electrical connections
have
been made
to
the
welding
power
source
and the
wire feeder.
2.
Be
sure
that the
welding
wire has been
properly
threaded and that

sure
that the proper
shielding
gas is
connected to
the
shielding
gas
valve.
4.
Place
the
wire feed
control(s)
in the
required posi
tion for the
welding
setup.
5.
Place the controls
on
the
welding
power
source
in
the
required position
for the
welding
setup (refer
to
welding
power
source
Owners
Manual).
6.
Wear
dry
insulating gloves
and
clothing,
