I know that this is a long shot but I was wondering if by chance ultrawide is 1: still a member of this forum 2: still has the same welder and finally if he or anyone would be willing to look up the ic number for the IC behind Q1, I believe it to be IC1 but not sure as no markings on board unless under the chip and the IC next to Q2 is marked IC4 and there are only 4 on the board but still only a guess, any help would be greatly appreciated, as a replacement board is going for more than $200.00 and I can repair this one for maybe $10

Thanks`
