Selecting Cable Sizes; Weld Output Terminals - Miller Dynasty 280 Series Owner's Manual

5-2.

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.
Welding Amperes
100
150
200
250
300
1 This chart is a general guideline and may not suit all applications. If cable overheats, use next size larger cable.
2 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 2 for metric use.

3 Select weld cable size for pulsing application at peak amperage value.
4 For distances longer than 100 ft (30 m) and up to 200 ft (60 m), use direct current (DC) output only. For distances longer than those shown in
this guide, see AWS Fact Sheet No. 39, Welding Cables, available from the American Welding Society at http://www.aws.org.

Turn off power before connecting
to weld output terminals.
Do not use worn, damaged, under-
sized, or repaired cables.
