Determine
the
distance the
control/feeder
is
to
be
located
from the
welding
power
source
and
then
connect
a
hose
from
the
shielding
gas
regulator-flowmeter
on
the
shielding
gas
supply
to
the
gas
input
connection
on
the
rear
of
the
con
trol/feeder.
Refer
to
Figure
2-4
for
gas
input
connections.
This connection
has
a
right-hand
thread.
The
shielding
gas
hose which
comes
from
the
gun
is
to
be
attached
to
the
output shielding
gas
connector,
labeled
GAS,
on
the
front
