Lincoln AC225 S

admin

Hi all, my first post on your page... well I can't seem to locate info. using my code: 8712-705 I need DC to use 7018 rod so I bought a 300amp full wave rectifier. will age have any effect on the transformer adding this rectifier?  I rarely use this welder only projects in the garage. 1/4in. Fillet welds, Lap Joints. Thanks for your advice.

Reply:I watched a guy weld using AC 7018 Rod on his Lincoln AC225. after he installed a Rectifier and welded it was a big difference, the flow was better, less splatter as well. I was mainly trying to find info. on my code. the video was on YouTube. thanks
Reply:You will need an inductor to go with the rectifier to stabilize the DC arc and a noise suppressor. Using the AC rod will be a lot cheaper.I have an old 300 amp Glen stick welder that has higher OCV. It burns anything I try.and welds great. Have used it to repair a lot of farm equipment.

Reply:It can be done but I would suggest buying a Miller Dialarc 250 or Lincoln Idealarc250 and be done with it. Nothing experimental about those machines. Unless you just want to do a conversion project.

Reply:Is this the smaller counter top AC 225S? Not worth even trying to convert it to DC.
