Product Description



Safety Shutdown prevents accidental shock if contact is made to the ladder elements.

This is a kit with plans and all parts included, requiring assembly.
It is also available fully assembled and ready to use.
Or as plans (paper or downloadable versions), with parts and assembly required.

The kit when purchased as a project kit is built in an open configuration where the ladder elements are exposed and the electronics are located beneath a clear plexiglas deck allowing visual exposure of all parts.

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 front 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 and speeds up the display. It also eliminates any arc hangup from forming.

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 extinguishes. 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, and overall height is about 22" with shroud. Runs from wall power (115 vac at 2 amps) through a standard three-wire grounded cord. 220 volt units are also available on request.
