I have a millermatic 175 that died. Ser#LE263696 Board#207466. The welder will feed for less than a second then just stops. Incoming voltage has already been verified at the control board and the cooling fan runs fine and I have no overload light on. The trigger relay and gas relay pick up when the trigger is pressed.

This is how far I have gotten:
when the trigger is pressed, I get about 30vac going to the main transformer (measured at RC6 & RC7 on the control board)then it almost instantly bleeds down to zero. When this happens I also get a 12dc to the drive motor for less than a second then it also bleeds off to zero. I'm just not getting any power from the board to the transformer or drive motor for more than a split second.

any help would be greatly appreciated
