I was not disappointed, admittedly the 3 Phase with an old Lincoln should be as smooth as it gets, the Miller in my shop was pretty darn close to it!
Most Lincoln ac/dc xformer type were single phase

Westinghouse, made a xformer type one (my neighbors has it) that was 3 phase, and had selenium rectifiers..

IT was very smooth, and had a curious
