Selecting Cable Sizes - Miller XMT 304 Owner's Manual

3-5. Weld Output Terminals And Selecting
Cable Sizes
A ARC WELDING
can cause
Electromagnetic
Interference.
~~$
To reduce possible interference, keep weld cables
as
short
as
possible, dose together,
and down
low,
such
as on
the
floor.
Locate
welding operation
100 meters from any sensitive electronic equipment. Be
sure
this
welding machine is installed
and grounded according
to
this manual. If interference still
occurs,
the
user
must take extra
measures
such
as
moving
the
welding machine, using
shielded cables, using line filters,
or
shielding
the work
area.

Weld cable size (AWG) is based
on
either
a
4 volts
or
less drop
or a
current density
of
at
least 300 circular mils per ampere.
