welding seabee : "With O/A you quickly learn molten puddle control. "
Hear hear! I'm a long time non-pro personal project welder. self taught. Stared with OA 'cause I was introduced to it in junior high shop class. Got my own setup when about 25. It just made sense, perhaps I warmed to it as prior I did a lot of soldering. Puddle control is - for me - real easy because of the opportunities of using pressure of the gas flow from the tip to manipulate the puddle.
Since then I got a MIG and after some time can do decent with it. Recently I got a stick welder but haven't spent much time with it, and am challenged. But the OA gas has always and still seems intuitively easy...
