That's what I said. Getting units out for video is apparently low on the priority list with Oleg. I have asked for a 250P for several years now to test. It's in his court.

No, you can't butt weld 3/8" steel. The "capability" we and our competitors refer to is not typically a buttweld joint. It is an edge prepared joint. It takes approx 1 amp per .001" of metal thickness to make a "butt weld" and get anywhere near 100% penetration.
