Re: welders?
With mig, I always ended up welding stuff with a series of spot welds. They do great little spot welds. With oxy/acetylene, I just weld a little section at a time and whacking the weldments down a bit with hammer & dolly as I go. I have a very small Victor torch that I purchased to do Chrome Moly aircraft tube repairs. I ended up getting better results with tig on the tube repairs by far but for sheet metal, hammer welding with the little torch still works the best for me. Shield gas is just not as effective on large flat panels as it is on tubing where you can confine the gas better. To each their own I guess. It just depends on what you are used to using and the skill level you develop with it.
