I looked up a wire gage calculator and it recommended 3 AWG so about $300-400 just for the wire. I’ve got 100 amp going to the conex right now and really only need a 20amp at most in there (light and a freezer) so I could use that breaker panel for the shop and just run 20 in there from the meter panel. Also have 120 going to the well house and only a 30 and 20 in that panel. Probably set up the conex to run the welder till spring. It’s a hf brand welder but for a c note I couldn’t say no. Plus it was brand new in the box. Never been used.
