I recently received a grant and am in the process of purchasing new equipment for my shop. I am looking for opinions on what type of MIG, TIG, and ARC welders you use in your program and what you like and dislike about each of them. There is a machine called the Fabricator 211i Multi-process which does all three from one machine. Does anyone use these? Hoping for some opinions on which machines hold up best and are easiest for students to learn on. Also, does anyone use downdraft tables instead of overhead fume systems? If you could re-design your shop what are some must haves?
