    Hypertherm has the Max 43 tech manual readily available on their site. I can't remember if it has the control board schematics (pretty close to the Max 42 board schematics from what I remember, different/simpler pilot circuit in the Max 43), but definitely has the power board schematics.

    When you disconnect the torch from the machine, what does the multimeter say? That machine uses a power resistor to limit current in the pilot circuit. If it stays closed, that might be what gets hot. Not sure though.

    Yeah seen a couple of the hypertherms 30s 45s for less than half i they get to reality it prob is nice never beat on but I think it to expensive but as a (mine) parts machine I'm thinking 750 is got the 43max for 50an it doing what I need oh by the way the handle is getting hot same place just behind the switch I know connection is tight double shrinkwrapped conn black tape on copper line seems still getting some kind of connection between pilot arc and main gas line any idea s still waiting on parts from Hong kong

    That seems like quite a bit for that machine. There's a Hypertherm Power Max 45XP near me for less, and probably other hypertherms around as well.

    Good for aluminum. I bought and fixed a few Lincoln Powerwaves and a Powermig 300 - sold the Powerwaves and probably should sell the Powermig 300 because it's worth more to someone else who does a lot more aluminum. I sold the Powerwaves (one 355 I converted to 355M, one 355M with two feeders) with push-pull and standard push guns - the buyer paid for both machines on his first job, and had been turning down aluminum work before. Granted, was in Washington where people use a lot of aluminum. Since I moved to New Mexico, not so much...
