Well maybe this is a good place to ask... Great to hijack a thread. I am a backyard self taught welder. I was told when making a MIG weld you want to swirl the torch. On Jody's videos he called it making e's hard to describe it. He even showed it when using a TIG. When you weld you run the torch like a lower case written e and keep hooking them together... It comes out like swirls or similar to stacking dimes. Then I see a lot of people weld straight across... The welds look more like a caterpillar.

Just another way of welding or is one better than the other???
