This is the welder that I use for my project. It is a DC+ DC- AC~ Tig welder and also a high frequency stick welder. It goes up to 270 amps so it can weld just about anything that needs to be welded. It is a $8000 machine that I am lucky enough to get to use daily.
The welding process is one of the most utilized fastening techniques when fabricating architectural aluminum railing. Take a look at this info and it says true, same as the blog of aluminum welding Tampa FL.
