    For many years RMS sold the Mini Anodizer with a separate isolation
    transformer. For the 3amp machine it was a 250VA transformer(about
    $70). It was essentially one to one. 120 volts in 120 volts out. With
    it in the circuit you could read only trace voltage between the
    leads and the metal box that housed it. Ahhh, but if you plugged the
    Mini directly in to the wall it was a different story. Full line
    voltage+* was just hanging there waiting. 

    The scenario is: 

    You are happily anodizing away and a connection comes loose in the
    bath. The anodizer is turned up to 100 volts. You pull the piece out
    of the bath and adjust it with a finger of your right hand. Thew
    phone rings you answer with your left hand. Wrong  number! As you
    turn back to your work you touch the case of the anodizer. Better
    known as ground! You are know the fuse. End of story.

    I am the proud owner of a Mini with a bit of the corner melted away
    from contact with its own hot lead. It was just a quickie demo and I
    took a short cut. Only once. 

    *The + is because the variable transformer in the Mini increased the
    voltage by 30%.
