Verticle up mig welding is not easy, you should have many years of welding experience. Go verticle down using a circle motion, about the size of a large pea. The circle method will ensure that you have penetration on both pieces of metal your welding. I have sunday off, I'll try to make time to weld a circle verticle down weld and post it.

I google " metal supplier " I found local companies who supplied it. I bought 2x3 for my sub frame. There is this place called bobco metals in Los Angeles.
