    Negative! I'm absolutely sure the polarity is correct. I've checked them a couple of times and had 4 others check it out also. I thought the same thing. As it turns out, I managed with little effort to get my first chromed piece this afternoon. YEAH!!! The first thing this morning I went to Home Depot and bought bare copper ground wire to hang the part by. Much larger than the #10 copper I was using. Then I hooked it by two spots rather than one. I also picked up heavy duty clips and some #6 stranded wire (black & red). I minimized the resistance as much as possible. It seems to have done the trick. The most damage was always at the point of contact with the hanger. Maybe I was burning it off, ya think? I do however get some foam around the work piece area Not a lot though. Is that a bad thing?

    i think the same thing as 48 buick does you have to have your power cords reversed.

    Hi:
    Are you sure you have the POS to the anodes and the NEG to the part?
    It sounds like your reverse plating....Is the bath foaming when you plate?

    can't get chrome

    I'm new to this forum, so please bear with me a moment while I describe my problem. Maybe one of you can help me out. I have no problem with the first three steps. Flash copper, acid copper and nickle. All the steps are done by the numbers and they come out great. Then when I get to the chrome tank, everything goes crazy. Again, I'm trying to do it exactly by the numbers but maybe I'm missing something. I have the anodes (2) placed in the tank with a jumper wire connecting them. The part I'm trying to plate is small, so the anodes are aprox. five inches apart. The part is a 2x2 angle iron 2" long. Therefore the amps are set at 16 amps. + to the anode and - to the part. Within a few minutes of being in the chrome tank, the nickle is stripped and sometimes some of the copper. It seems to be more severe were the wire hook is attached. I thought that maybe the batch was bad so I mixed up a new batch, but still the same thing. I've been back and forth with the tech. dept. for a couple of days now but we can't seem to figure it out. While I'm on this subject, exactly how critical is the amp settings. (+ or -). I now have a digital amp meter set up so I can get it right on the button. I sure would appreciate any help you could offer as I'm about to lose my mind.
