ECN Forum Forums Code Related Discussion NEC & other Code issues Welder receptacle rating

thanks for your thoughts guys. I knew I came to the right place.

Right now I have a 50 amp OCPD, and watching how she does with the work. I'm not comfortable going up in size with the OCPD unless I change out the receptacle and plug to maybe just a disc. I know we size motor discs, plugs and recept's and to FLA and HP. That's EZ. Perhaps I'll call the mfg. I know we upsize OCPD for inrush on a still rotor with a motor. I'm wondering how the welder does on initial amps with that 50.
