Re: Voltage for electroplating
The voltages vary depending on the process and also surface area being plated. It is actually the current that is critical.
My advice... Buy a variable current/variable voltage power supply. They are not that expensive compared to the grief you will suffer not being able to easily vary both voltage and current. I got a 30Vdc 60 amp one from a HAM Radio supplier here in aus for $240 Aus dollars. There are heaps on ebay. Mine says it is only adjustable between 1Vdc and 30Vdc, hence the low price. I spoke to the guy who sells them and he said they actually go down to 0.8Vdc which means it is fine for all tank electroplating. 1Vdc can be a bit high for zinc. 0.8 is fine.
Alternately buy one of the ones Caswell sells.
