220 Volt Welder Circuit
What size circuit breaker, wire gauge? I have an 8 foot run. Conduit is installed.
Thank you, Charlie.

Welcome to the forums.
Look at the ID tag on your 240v welder. It should tell you the operating current.
What does it say ?

Usually a compressor runs on a 240v 20A circuit and a welder can be from 30A to 50A.
Two circuits.... one for each.

240v requires 2 wires (hot-hot) not three. #12 is good for 20 amp on most circuits however with welders wire size may be smaller in some cases do to duty cycle.
You have the cart before the horse. You need the actual devices to plan the circuits.

Compressors that don't come with a cord and plug, usually needing greater that 20A circuits, need to be wired based on the motor name plate HP. A NEMA 50A outlet needed for most 240V welders are only rated to be used with motors up to 3HP. A NEMA 60A is 3.5HP. HP above 3.5 should be hardwired unless you used expensive PIN and Sleeve plugs.

Input amps is what is needed to determine the circuit breaker and wiring needed.
What is the model number. When I search 'Titanium 200 welder' it seems it could be anything from 20 to 200 amps depending on the model.

Can't find that info.
In the meantime, this popped up and couldn't resist. Cheap enough.
