IND50 - Electrode Induction Heater
Induction Heater

IND50 Instructions

This induction heater is capable of heating metals to over 1500 degrees F. It can be used in the processing of gas discharge tubes often used for plasma, neon displays, laser discharge tubes, spectrum tubes, etc. Output power of the heating element is approximately 150W with an operating frequency of about 50kHz, and is intended for intermittent use of up to about 30 seconds heating at a time. This unit is not intended for high-volume industrial production, as the MOSFETs will overheat under extended use. (Users may choose to experiment with oversized heatsinks and active cooling of the MOSFETs, but this is not recommended and not covered by our warranty.)

Projects high frequency waves capable of igniting lights and producing energy fields without wires or contact! Excellent for testing neon or fluorescent tubes without removal from their sockets.

Plasma energy emitting device is very useful for testing fluorescent and any other gas discharge lamp without removal from the socket. Simply bring the unit near the lamp and note if a glow is occurring indicating lamp is usually OK. Gun is an excellent leak detector for checking otherwise non-detectable leaks in vacuum and gas systems.

Hand held, built in a wand configuration containing batteries (not included) with a telescoping emitter probe.

  • Checks All Type of Gas Discharge Tubes Without Removal
  • Handheld 1.5" x 12" Cylindrical Lightweight Enclosure
  • 48" Telescopic Probe Extends For Hard to Reach Places
  • Battery Operated Uses 8 Type AA Batteries
  • Requires Only Proximity to Light Most Displays

PLPEN1K - Plasma Writing and Etching Pen
This is a project that's becoming quite popular. It allows the etching of very fine designs into any nonconductive surface. A piece of unfinished wood is a fine example where you can actually draw with great precision using the plasma flame in exquisite detail. The device is simple and safe to use and can do many things for those that want to try something new with natures 4th state of matter!


"Burns In" Using a Plasma Arc -- Provides Hours Of Creative and Profitable Entertainment!

This interesting project allows the user to burn precise and very fine lines into paper, cloth, wood, plastic or most other non-metallic materials. The burning mechanism utilizes an electrical plasma produced by a high frequency discharge that forms at the emitting pin of the pen. Power is by built in batteries or an external 12 vdc wall adapter transformer. Once the user becomes familiar with operation, many designs requiring precise engraving will be at his finger tips.

The device is shown built in a tubular enclosure of 6 x 1.5 inches od. that encloses the batteries and all electronics. The etching section is a pen-sized stylus connected by a length of flexible wire.
