About Wire and Cable

Use For: Welding
600V AC: Bend and Stay
600V AC/DC: Flexible
Temperature Range: -55° to 220° F
Insulation: EPDM Rubber

This cable withstands abrasion, oil, and the rough conditions found in welding applications. It’s flame rated VW-1 to meet requirements for vertical flame testing.

Class K cable is for general purpose welding applications. It bends and stays in the position that you bend it.

Class M cable is more flexible and durable than Class K cable.

Battery Wire

Use for vehicles
60V DC Wire: Flexible
600V AC/DC: Ultra Flexible
Temperature Range: -40° to 190° F

Connect batteries in vehicles and generators.

Strand count is the number of strands followed by the size of the individual strand.

Wire with an EPDM rubber insulation is ultra-flexible for use in applications that require tight turns. The insulation resists abrasion and oil.
