    My argon have now ran for about a hour on the lowest power i can turn it down to without the dot starting to flicker.

    Here are some new pics, lower power i can get without flickering:


    Max power:


    View of the laser head running:


    The whole setup:



    The tube voltage is 82-85V no matter the position of the pot, measured between the filament centertap and the anode wire in the psu end of the umbilical.

    Time for an update.

    I´ve started on the real psu now, this is the box it´ll live in:



    I´m still waiting for parts tho, a new IGBT, relays, led´s and some boads to build the control circuit on.
