I have been keeping my eye open for something about 10 Kva to run my plasma cutter in my workshed. At the moment I use a 60 year old 4Kva S.O.M. Because it doesn't have the later transformer regulator it requires a bit of patience when you whack a sudden load on it is just a bit slow to respond or gives up and drops out the contactorand sulks, a bit like me who is just a bit older than it. The plasma will run at 30 amps on an 8Kva petrol generator and sometimes I would like to cut something a bit thicker than 0.25 in plate. The compressor is powered by an LD1 which is a lot more reliable at starting than the B&S it used to have. The workshop is about 1/2 Km from the house and the original quote to run the power would have required a casket win to finance it.
