RE: ATM anodizing problem

[Adrián Toledano <atoledan@prodigy.net.mx>]

Thanks to the responses.

I follow the sugestion and throughly checked all the setup.

The "12V 5A regulated power supply" I was using (I borrowed it from a
friend) happened to be defective in several ways. It seems that it was
incorrectly repaired by somebody, but it had the following problems.

- Inverted polarity. Terminal marked + was - and viceversa
- It was not 12 V but 9
- It´s unregulated
- it was unfiltered
- 6V AC at the output.


I somewath fixed it using a diode at the output and succesffully anodyze and
dye a small pice of aluminium.


I still have one question, How can I have more current in the anodizing
setup without increasing voltaje?, is current a function of anode area and
electrolite concentration?

Thanks very much

Adrian
