Agreed, I earn a living with a TIG torch (past tense) so I can be a bit hyper critical on all things heliarc! The first time I had to submit tabs for certification (Stainless) I failed. I sent the failed tabs to my Dad as the failure was due to color ripple, he couldn't believe it. Stingy inspectors back then. Black iron was always much more lenient. Not often anymore I get stuck under the hood at work unless I am teaching. Mostly just make sure my guys don't burn the place down. I am finding my eyesight has really deteriorated in the last few years.
