By small I was referring to amperage (<200) with a nice compact gun for getting into tight places for welding on rollcages. I'm not super familiar with the smaller machines but I believe most of them are limited to approximately 2 lb spool. I'm thinking in the $350 neighborhood for a 140-160 amp machine. I'm not sure what arc force is. Any ball park idea when these may arrive. I realize they may be on the slow boat :-)
