arc or mig

i would go with arc, deeper ,easier penetration i found,

but i do love mig welding, it's alot cleaner. and easier

well does anyone know bout those 115V mig welders are those anygood???

If you get the right one. there are many cheaper inferior 110 units. Lincoln sp series welders are my personal favourite BUT miller has good units too.

tractor supply has a mig for 450 with argon hook up im not sure what brand it is???
