Product Description

The finished unit intended for museums and similar displays is fully enclosed with the traveling plasma arc inside of a clear plastic shroud. The base of the unit is formed from sheet aluminum and houses all the electronics with the controls being on the from panel. A black textured piece of aircraft lexan is formed into the cover.

An internal fan supplies a slight over atmosphere pressure at the bottom starting point of the arc ladder to prevent any arc hangup from forming.

Also available in other configurations:
- as a kit with plans and all parts, requiring assembly
- as paper plans with parts and assembly required
- as downloadable plans for roughly half the price of paper plans


Produces a traveling wave of plasma that starts at the base of the ladder electrode elements, rises and widens as it ascends and evaporates into space. The vertical travel distance of the arc is about 16" and reaches a width of 2-3 inches as it extinquishes. It then repeats and continues traveling up the ladder, evaporating and restarting.

Allows varying the arc texture by a simple control that also is the main power switch. Texture can be a thin wispy like spark to a heavy hot energetic plasma arc.

Size of base is 9.5 x 9.5" square with an overall height of about 22" (with shroud), and a weight of about 4 pounds. Runs from wall power (115 vac at 2 amps) through a standard three-wire grounded cord. 220 volt units are also available on request.
