Weld Output Terminals And Selecting Cable Sizes - Miller Maxstar 200 STR Owner's Manual

4-7. Weld Output Terminals And Selecting Cable Sizes*

NOTICE − The Total Cable Length in Weld Circuit (see table below) is the combined length of both weld cables. For example, if the power source is
100 ft (30 m) from the workpiece, the total cable length in the weld circuit is 200 ft (2 cables x 100 ft). Use the 200 ft (60 m) column to determine cable
size.

!
Turn off power before
connecting to weld out-
put terminals.
!
Do not use worn,
damaged, under-
sized, or poorly
spliced cables.

This chart is a general guideline and may not suit all applications. If cable overheats, use next size larger cable.
*
**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.

( ) = mm for metric use
***Select weld cable size for pulsing application at peak amperage value.
