For arc welding cable applications length in feet for total circuit for secondary voltage only do not use this table for 600 volt applications.
Welding cable ampacity in conduit.
Welding cable ampacities single conductor required cable sizes.
Welding cable ampacity also known as current capacity or amperage rating refers to the maximum amount of electrical current that a cable can safely conduct.
The total circuit length includes both welding and ground leads based on 4 volt drop 60.
Welding cable ampacities single conductor required cable sizes.
I have seen welding cable and dlo used in conduit to send power to pieces of equipment rtu chillers etc if you go by the manufacturer ampacity charts welding cable has a lot higher ampacity rating than a standard thhn.
This would give the advantage of using a smaller and more flexible wire.
