I have purchased a Prime Weld 225x tig welder with the intention of teaching myself to weld and fabricating parts myself. I have 4 types of metal to put to put together: Aluminum, Stainless, Inconel, and Chromemoly. I started with Aluminum and have been at it for about 4 hours. I've burned through alot of coupons, but I feel comfortable holding the torch and making a good puddle. Now I have to get the hang of introducing filler and working a good rhythm. I plan on making most of my welded parts including the tailwheel support, aileron brackets, engine mount, exhaust, and other incidentals.
