Good morning friends, good morning Steve, and thank you for paging me lol. this circuit seems to be some sort of power unit equipped with a couple of thyristors at the top, and it's capacitor looks to be deteriorated a bit, in the middle, but do not know more though.
Been struggling with welding practice these days, to thin sheet of alu and steel. This week I am trying some fusion welding to thin steel sheet, 0.5mm thick, mean welding without filler rod/wire, but not very easy job to accomplish a longer span.
