Tru-Etch Etching Machine

The small Tru-Etch etching machine will etch all types of metal including copper, steel, and brass.  The paddle design splashes acid up against the plate mounted on a workholder. The Tru-Etch is fully automatic, just set the dial for depth desired and the timer shuts it off.

However, the precision needed for certain fine lines and images cannot be obtained using a paddle etcher. For these applications the Super Etch etching machine is a better choice.

This model has a work rack 11″ high x 14″ wide.   The dimensions are: height 14″, width 15″, length 20″.  The etching tank is made from welded PVC material with a clear top and side so that you can easily observe the etch while in progress.  The-Tru Etch is supplied complete with 1/4 HP motor, electric timer, heating pad and controller, hydrometer, and 6 foot extension cord, all wired for easy use.
