Steve called in yesterday with a side piece that he had welded with his MIG. Seems the the MiG ( I thought he had a TIG) is just not quite right for welding 1.6mm Ali. Can't slow the wire feed enough to get good penetration and wont run the lighter wire. Had a little test run with my TIG so looks like when he next gets home from a shut down he'll bring the bits over and use mine. I think it is a win for both of us in that between us we will learn more of how to utilize a complicated machine. The other thing is something that I found to be an issue with home building. When you run into a technical issue that becomes a road block and your the only fool you know of that meddles with crazy stuff like sidecars. Stymied its what you become. Now Steve seems to be quite capable having built a complete aluminium boat with his MIG. So its good to have a second opinion/option.
