Got the welder going again tonight. I didn't get to do much except strike a couple arcs, since it was starting to thunderstorm, but it seems like a stronger arc than when it was working before. It ended up being a whole slew of problems, not sure if they all happened at once or if it was cumulative, but I am thinking the latter. Out of 8 diodes, 5 were bad (3 dead and 2 shorted). The optocoupler and a resistor were burned up. 1 burned trace on the circuit board, a couple other melted solder joints. The diodes themselves were going to cost around $100, but after enough digging I found another brand with the same specs, and total cost with shipping was under $40. That includes a spare optocoupler and 2 spare diodes.
The board was a piece of cake to repair, after soldering 3 mpguinos.
This is a downstate weekend, so I should be able to get going again on the kammback/boattail early next week.
