I have a PowCon Plazma Plus. My unit is also set up with the Power-Drive I/E feeder that sets on top. The feeder will not work with the fuse out. It may have got lost during the move. Anyway, I really like this unit. Parts and technical support are available from Arc-Products. I have ordered the manual and consumables for the Plazma unit. Prices are about the same as Miller and Lincoln. $450.00 is a pretty good price for a working unit. Paul
