Equipment
Location
When
deciding
on
equipment
location,
consider
the fol
lowing:
1.
The
equipment
must
be
mounted
to
a
structure
capable
of
supporting
the
weight
of
the
equip
ment.
2.
The
lead
lengths
of
the
cords
supplied
with
the
equipment
will
limit
the
area
in
which
the
equip
ment
can
be
located.
Some
cords
can
be
ex
tended
by
using
optional
extension
cords
(check
with
welding
equipment
distributor).
3.
The
interconnecting
cords
must
be
routed
so
that
they
are
not
caught,
pinched,
or
strained
during
welding
operations.
4.
One
weld
output
cable
must
be
routed
to
the
Gas/
Current
Sensing
control.
5.
Welding
wire
must
be
routed
so
that
it
does
not
contact
the
weld
control
or
any
other
grounded
equipment.
C.
Equipment
Installation
Obtain
appropriate
mounting
brackets
or
adapter
plates
as
necessary
and
mounting
hardware.
Prepare
struc
ture
for
equipment
installation.
Secure
weld
control,
Gas/Current
Sensing
control,
and
all
other
equipment
onto
structures
in
the
welding
area.
