A TIG welder is an arc welder, so the table in 630.11
If duty cycle is 100% then there is no reduction in conductor ampacity allowed.

Insufficient question for an answer. What brand and exact model? Few welders are 100% at max or even "rated output." You received no instructions or manual with the machine? FWIW, I'm a welder and active on Miller and Hobart sites answering welding machine electrical questions regularly.

What other table than the one I mentioned would apply? It is either an arc welder or a resistance welder isn't it?
If duty cycle is 100% then the multiplier is 1.0
The table for resistance welders doesn't even go to 100%

Your table applies. We can help with the question if we know more.

More help may or may not be needed, all that was asked is what table to use.

You're right. I'm used to going all the way. And like you say, it doesn't really apply at 100%, but I know enough about welding machines and typical people asking about them to also know there is a high likelihood the question was wrong.
