my dad worked for northwest airlines. he showed me how to weld titaniam on a fan blade of a dc10. and cought my intrest. took welding in high school and votech. been welding for 37 years now. sheet metal guru on sst,hrs.alum,copper,inconal,brass,cast steel. and all kinds of garbage metal. mig is ok, but tig is the way to go. some call it an art. not to bragg. but it came easy to me.
grab a miller 211 and it will help teach you how to weld. they make it so simple now with the new tech that is out there.
good luck on your new venture in welding.
