Hi Chaz,

I have just acquired 1/2 of a TRIAC VMC today so will follow your threads with interest. The Miller was going for scrap. Unfortunately I don't have the controller or a schematic but do have the monitor/PC, not that I think it of much use on its own. I have to decide if the miller is worth the time of effort to "upgrade". Even with the latest electronics/controllers its not as simple as plug and play. I agree its heavier than it looks. The C of G is not where you expect it either. The lifting eye on the top gives the game away.
