Wielding Cable in conduit

[JGC]

Can I use 3 conductor 250MCM wielding cables for 400 amp feeder and breaker for a trailer in 3" conduit through out the trailer?

You can only use "welding cable" as a NEC wiring method if the cable has an additional listing of a type shown in 310.104 and then you have to use listed termination products for the fine stranded cable.
Generally speaking it's a "no go"

We use Type W cable for a bunch of Navy experimental systems, but they are "cord and plug" connected with large pin/sleeve connectors, so not a Chapter 3 method.
