The

is
a

Consumable

High

gas

the

is
designed
specifically
for
the
gas
metal-arc
consumable
electrode
welding
process.
It
is
air-cooled
and
rated
at
200
amperes
dcrp
at
100
percent
duty
cycle
using
CO2
shielding
gas.
The
gun
is
shipped
from
the
factory
as
sembled
and
ready
for
operation
with
the
specific
wire
size
components
ordered.
Only
minor
changes
of
parts
in
the
gun
and
wire
control/feeder
are
necessary
to
convert
to
0.030
and
0.035
or
0.045
inch

5.
Ensure
that
the
flat

IMPORTANT
The
outlet
guide
should
be
positioned
as
close
as
pos

to
the
drive
rolls
without
touching
them.
This
gives
the
maximum
column

is
applied
at
any
time
the

should
be
rechecked
on
