From what I've read constant current means constant migration speed, but as electrolysis occurs the resistance goes up and more heat is generated. Constant voltage means as resistance goes up due to electrolysis, current goes down and so does migration speed, but heat stays low.

Ack. I meant voltage fixed at 75 or 50 and let the current vary. My
gelbox is a simple affair. It's lets you choose 6 or 7 different
voltages to run at and lets you program the timer.
