In our local jurisdiction where the building was like a pole barn with a concrete floor, the local inspectors required us to use all GFCI circuitry as they considerd the poured concrete floor the same as outdoors CHECK WITH YOUR LOCAL AUTHORITY FOR THE ANSWER IN YOUR LOCATION.
In a shop I prefer the quad outlet boxes (two duplex receptacles side by side) in metallic grounded boxes with wiring in conduit as it affords more protection then exposed romex, at least around the lower perimeter walls REGARDLESS if Romex might be permissible.
Although it may be overkill and MORE then the NEC or your local authority may require at a minimum, I still wouldnt want more then 3 or so quad outlets on a single 20 amp branch circuit. Also you want to stagger the branch circuit feeds so no two boxes near each other are on the same circuit i.e. Circuit A next to a B next to a C etc.
I would use a good grade (NOT cheap residential) 20 amp 2 pole 3 wire grounding receptacles (NEMA 20 R) instead of 15 amp receptacles and, of course, those require 12 gauge 3 conductor wire, Hot Neutral and Ground
I would NOT use multi wire branch circuitry where a common Neutral can serve for more then one phase conductor.
At the Air Compressor Id use a wall mounted Safety Switch disconenct even though a simpler cheaper plug n receptacle may serve as the in sight disconnecting means, they are not very expensive and Id sitll have one even with a plug n cord arrangement.
The Compressor and Welder switches n receptacles need to be sized, of course, for the loads DUH and many welders require a 50 amp receptacle and service branch circuit.

Unless you are from another planet, physically or otherwise, I don’t think our internal combustion buddies will talk and tell us their problems. But, on the other hand, there is a secret language that our mechanical companions readily do speak. It is an interesting form of communication that involves all the senses of the listener. In this series we are going to investigate and learn the basic rudimentary skills of understanding this lingo.
