You however are more brilliant than than the people who have been building hundreds of cars, structural engineers, and the people doing the testing because you have a Millermatic and a Flow Meter. Big deal who doesn't have one. If you look at your super duper spool it's probably ER70-S2 wire, maybe ER70-S6. You just can't control the heat as easily. Go back to beating tubes with a hammer for testing. I don't know where some of you people come from, but I've never seen a forum like this where people don't want correct information.
