Default Re: first timer needs advice

First, your off on using the 720 calculator, with 11.25 peak voltage means you have 4.5 CD which is ok. The amp setting of 1.38 for a 45" SA is ok. The 20 minute run time is way off. It means you are attempting a coating thickness of between .1 to .2 mil. That's not enough to dye. Try .5 to .7 mil for good dyeing qualities.

The PS is your next problem. Since it it not CC capable, you can adjust your voltage to get your amperage and keep adjusting to maintain the amperage whichmay get old after a 80 minute run for a .5 mil coating or turn the voltage to 12V and use light bulbs to limit the current or find a PS that is CC capable. Whatever you want. The easiest in the long term will be a PS that is CC/CV capable.

You have positive to the part? Negative to the cathode? What kind of cathode and how is it attached?

After you dye the parts, they can be left out. They will start to seal on their own but it will not be as good a seal.

Cipher through this and see if you have any more questions. It takes a little to get going but it'll be worth it. SS
