Selecting Cable Sizes; Connecting Weld Output Cables - Miller Electric Dimension 652 Owner's Manual

4-9. Selecting Cable Sizes

NOTICE − ARC WELDING can cause Electromagnetic Interference.
To reduce possible interference, keep weld cables as short as possible, close 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. Contact your
2
distributor for the mm equivalent weld cable sizes.

4-10. Connecting Weld Output Cables

Tools Needed:
3/4 in (19 mm)
!
Turn off power before connecting to
weld output terminals.
!
Failure to properly connect weld
cables may cause excessive heat
and start a fire, or damage your ma-
chine.

output terminal and secure with nut so that
weld cable terminal is tight against copper
bar. Do not place anything between weld
cable terminal and copper bar. Make
sure that the surfaces of the weld cable
terminal and copper bar are clean.
