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.
