Electro Chemical Etching
Using low voltage electricity to mark or etch metal. AC will mark. DC will etch.
Etching Machine
You can etch with 3V DC and you can mark with 6V AC up to 30V. Using 12V 2A is good.
Stencils
The stencil blocks electricity except where the artwork will etch.
Pads
Craft felt makes very good etching pads. Thick pads work for etching and marking. Thin pads are only for marking. They get gunky.
