I learned to weld when I was probably 10 to 12 years old watching my dad. Back then in the 50's all he was using was oxy/acetylene. My uncle actually had an acetylene generator ( kinda scary thing, never saw it used). Dad made lot of things with it. Later he got a stick welder. He and I used it a lot. I'm still using stick almost all the time in my home shop. I also have oxy/acetylene but don't use it much. I have used a miller 210 mig but never got comfortable with it. I normally weld steel up to 1/2 " trailers, hitches, towbars, bumpers, and various other projects. I guess what I'm saying is I'm 75 years old and comfortable building things the way I always have. My welds are strong, probably overbuilt, but I've never broke one.
