Tinker, Can you give me some idea of what is causing the pinholes in the tig welds that we get sometimes? I really would like to figure that one out. One of the two brothers was telling me that he thought he had figured out how to get better welds on the small items that they sometimes weld for me, but I'm not sure if it had do do with turning the heat down or doing something with the polatity, maybe? Is that possible to do with a Tig? Everything I take them is claen and polished enough to be sure there are no foriegn particles in the welded area, so I know it is not the parts that are contaminating the welds. Bob H.
