MAINTENANCE
Ensure,
that
all
electrical
power
to
the
welding
power
source
and
the
weld
control
unit
is
completely
disconnected
before
attempting
any
inspection
or
work
on
the
Spool-Pak.
Usage
and
shop
conditions
will
determine
the
frequency
and
type
of
maintenance.
Inspect
equipment
as
follows:
1.
Repair
or
replace,
as
required,
all
cable
and
conduit.
Give
particular
attention
to
frayed
and
cracked
insulation,
connections,
and
areas
where
the
cable
or
conduit
enters
equipment.
2.
Remove
grease
and
grime
from
components;
moisture
from
electrical
parts
and
cable.
3.
Purge
the
interconnecting
conduit
with
compressed

ADJUSTMENT
(Figure

Spring
tension
on
the

may
be
adjusted
to
ensure
proper
stopping
of
the
wire
spooi.
Loosen
screw
(Figure

and
slide

up
or
down.
Sliding
the
bracket
down
will
increase
the
brake
pressure,
thereby
causing
the
spool
to
stop
faster.
Some
small
slippage
of
the
brake
is
necessary
to
keep
the
wire
from
snapping
as
the
wire
feed
motor
coasts.
When
the
proper
spring
tension
is
obtained,
tighten
the
screw.
