Another Info Unlimited first! We are the only ones who currently make this Jacob's ladder, which is not a typical Jacob's ladder -- instead of a thin and noisy spark, this Jacob's ladder outputs a wide, soft, and quiet plasma flame. It can be left running indefinitely and the noise barely noticed. Also, a normal Jacob's ladder uses dangerous transformers which are potentially lethal if the output is touched while running. But this plasma arc Jacob's ladder is inherently safe -- none of the electronics, the transformer, or the ladder are lethal (they can cause a good burn if touched when running, but they are not lethal). These inherent safety features are a marked improvement over a standard Jacob's Ladder.
The spectacular display of a plasma arc, softly dancing as it moves up the metal rails, is sure to fascinate and amaze all those who watch it. A traveling wave of plasma is produced that starts at the base of the ladder electrode elements, rising and widening as it ascends and evaporates into space. The arc can reach a linear width of over 6 inches, but it's curved length can be well over a foot. It then repeats and continues traveling up the ladder, evaporating and restarting.
The arc texture can be varied 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.
The metal "ladder" itself runs about 5 feet high, with the device having an overall height of about 6.5 feet. Includes a music option, safety shutdown, variable spark texture, remote pushbutton starting, timer option (variable up to 5 minutes, or turn off timer for continuous operation), and active air cooling making it suitable for 24/7 operation. Internally selectable 110V or 220V native operation allows this Jacob's ladder to run from US or international wall power without the need for a step-down transformer. The outer dimensions of the protective tower enclosure are 12" x 12" but can be built to a different size if you have special requirements (we will need a drawing from you with your dimensions).
The base of the unit is formed from sheet aluminum and houses all the electronics with the controls being on the from panel. An internal fan supplies a slight over atmosphere pressure at the top of the tower to keep the ladder cool, and also eliminates arc hangup from occuring.
