 You interested??? 
 
 I found a power supply on ebay that its output is rated at 0-120vdc and 0-3a for about $300 shipped. I have found others that are the same voltage and 1a of output for a little over $100. One thing I am not sure of is exactly how much current I really need. From what I have read doing small stuff is not going to require much. The larger items will require more though. I would like to buy as much power as I can right up front. Does that seem worth it?

 Interesting. I ask because it might be possible to approximate tank resistance. If you know that it might help determine how much power you'll need.Originally posted by inline 6 View PostThere are any # of easily accessible products to make that. What seems to be more important is a good etcher.Men have become the tools of their tools.

 I didn't anwser directly because I have not actually done any yet and have not made up any of it. I am doing small pieces, keep that in mind. I called a place that has 30yrs. experience with it and they sell a small power supply that only goes up to 1a of current. The told me that was plenty for small parts. They sell a larger one that will do 7a of current and they said that one will do several square feet of material at once. So I man going to try and find something in the 1-3a range tops.Originally posted by BERNIE MOSFET View PostInteresting. I ask because it might be possible to approximate tank resistance.

 I have taken power systems class and I am taking switch mode power supply design class at UTA.Originally posted by inline 6 View PostI am looking for info from someone here who has some knowledge about building a variable DC power supply that is powered with regular house hold 110 AC. I am needing a supply that can output from 0 - 150 or 200v and a adjustable current level from 0-5ish amps. Any first hand expierience here????
 
 Several ways I can think of.
 
 This could be done first with a full bridge rectifier circuit that will take the AC 120Vrms and rectify it to a about 108Vdc. A buck boost converter can raise(boost) or lower(buck) that 108Vdc to the level that you would need.
 
 Any easier way with less regulation of the output would be to use a variable AC to AC transformer with a full bridge circuit. The output Vdc would vary as the transformer changes.
