A few projects I want to work on are some slots in my toolbox (aluminum) for an air compressor, bumper (who doesnt want to do this), and a bed rack to hold a high lift/spare tire or whatever else i decide to do. Also have some things I want to build that are non truck related but everything will be a max of 1/2" steel and a min of whatever guage i use for toolbox slots.
So i guess my question is how hard is mig welding vs tig welding, would i be able to learn without any more classes, and would a 110 mig be able to handle these projects. i know with the low voltage i will have to work with the corners of the thicker stuff to get good penetration but I have quite a few moves coming up in my future and im not sure if i will have access to a 220 plug.
You're gonna want a 220 machine regardless if you want to do aluminum. A 110 machine will struggle at 1/4" steel so keep that in mind.
As far as difficulty, mig is about a million times easier than tig. For mig aluminum look into getting a spool gun.
