I am about as much of a newbie as you can get.

I've been practicing with my MIG and just recently got my Power Plasma 50. I've been able to test it and learn how poor technique can create a lot of blowback

My first project will be a welding cart. I'm going to use square tube for the cart, based on designs I've seen here.

I just wondered if anyone had advice on cutting square tube before I give it a shot.

Thanks!
