multiple passes on aluminum

by Clark

I bought a $400 dollar welder for odd stuff around the house and garage. I unfortunately did not have a budget for a better welder. I am welding 1/4 inch aluminum to 1/2 inch aluminum. Can i multipass it to get my strength? any recommendations?

that is pretty thick stuff for around the house...yes you can use multipass. a preheat of around 200f with some type of torch will help also.
