Next is the copper ground connected to the nozzle, the idea of this is to stop the sputtering, if possible and provide a sort of pilot earth. Inside shot of the box, again note the grounding stubs bottom left of the door area, three green wires go up to the screens on the output cables, also there is connection from the door earth stud to the main box earth sud and the mains is also filtered:. OK some pictures, first one is the grounding connection to the back of the plasma unit, ,įrom here it goes to to the underside of the main frame and the disposable frame the metal being cut sits on:-įrom here a grounding strap goes up to the control box, bottom left of the picture:. So not a case of one part open but both outputs of the chip just very low output. Have toi use AC on the meter during stepping as it switched pos to neg, neg to pos etc. On a duff drive either X or Z axis I only get around 6 Volts AC. On the Y axis that still works when I move a stepper motor I get 25 Volts AC across the AP and AM connections and the same across the BP and BM windings. A few pictures taken these are below and I also put back in my duff control board before I repair it. The power supply is a Lambda power supply as mentioned.

Run the plasma up with out covers and the HF unit is not running all the time, just on start-up and when the nozzle goes over a hole when you can hear the sort of juddering when it takes out the control gear. Power Supply / Phases (V-Ph)240v - 1 +/- 15%.OK just managed to get 20 minutes in the garage.
