I'm in the same situation as you. I'm calling the electrician to hook my welder up because if a fire started from my welder, which isn't crazy uncommon on something that melts metal(I'd have a fire extinguisher nearby) insurance has grounds to deny your claim as that was never put in by a certified electrician so as far as they know it could have been done wrong.
It's not too much more expensive, you could even supply parts and so most of the labor but just to cover your bases it's a good idea
