Even though I agree it is a flawed design, Miller and Hobart have been using this spool hub design for well over 10 years. My Handler 187 and 210 MVP produce very smooth arcs (virtually spatter free welds on 1/8") with the hub rubbing on the sheet metal. I agree though that shimming the hub off the sheet is an improvement to the design. MY local ACE hardware stocks a perfectly sized nylon thrust washer that fits between the shaft and the hub, eliminating the need to shim the shaft off the sheet metal like you did.
No announcement yet.
Problem with Miller 211...since it was new
