I was at a garage sale today and saw an electrical device that I thought might work for etching knives. It was a box with a dial and two sets of plugs. It had two wires with aligator clips at one end and plugs at the other end. There were several choices for the voltage and amperage that could come from the box by plugging into one set of plugs or the other and turning the dial up and down, The choices were as follows.
Plug set 1
0 - 15V 5A
0 - 6V 10A
Plug set 2
0 - 20V 5A
0-10V 10A
There was a switch by each set of plugs to choose volt and amps needed and the dial was used to dial up or down those ranges. I'v seen where people use 9V batterise to etch but I'm not sure about the amps
My question is what kind of volts and amps do I need for etching? Would anything in those ranges work for etching? The guy wanted $10 for it.
