Electrochemical Etching Power Units

Monode's electrochemical etching power units provide a low voltage secondary power supply that can be switched between AC and DC output. Most power units provide between 6 – 44 volts output, controlable via a rheostat.

All of our etching power units contain either an internal thermal overload or an external fuse for operator protection, and feature banana jacks or polarity receptacles for use with cord sets.

Power Units for Other Uses

Monode Stain Removing Kit

Electrochemical Etching – Weld Stain Removing Kit

The Monode Stain Removing Kit removes burn marks from welding joints.

Etching Accessories


Electrochemical Etching – Hand and Finger Grounds

A hand ground and knife edge are used with small and large bench fixtures. A finger ground is used for speedy handling of parts when marking on bench fixture.

Junction Box

Electrochemical Etching – Junction Box

Contains three sets of color-coded outlets to supply multiple holders with current from a single Monode power unit.

Three Wire Cord Set

Red, black, green and yellow banana-type terminals with slip-on alligator clips.

Inline Foot Switches

Available for some units to enhance operator control.

Male and Female Adapters

Male adapters are for cord sets with female connectors and Monode holders. Female adapters are for banana plugs and holders fitted with a 0.140" male connector.

Stencil Cleaner Trays

Electrochemical Etching – Stencil Cleaner Trays

Monode stencil cleaning trays serve as reservoirs for the electrolyte and are connected to the yellow jack on Monode power units. The reversed polarity current electrolytically cleans the stencil on hand pads or inspection markers.
