I have had this welder for a few years and been using it quite a bit, but want to figure out how to "fine tune it". So I need manuals and any other info I can find. It is a Aircomatic 300A pulsed arc welder M#3-DCPA-224A S# R355105 and wire feeder M#AHF-T S#5288.

Also, how is parts availability, I know probably not great, just thought I would ask.

Thanks in advance
