How the Doug Coil Machine Operates

The Doug Coil machine produces a magnetic field with frequencies ranging from approximately 20 Hertz to 2200 Hertz. It is powered with an amplifier that results in power output of approximately 750 watts. The 200 gauss magnetic field produced by the copper wire coil alternates (or oscillates) at a selected frequency. Frequency refers to oscillations or reversals of the magnetic poles each second. Frequencies within the range of 200-2200 can be operated for varying lengths of time. At the lower end, the machine can operate for up to 30 minutes without overheating, and at the higher end, 5 minutes of operation can be attained. 

The QSCHD amplifier powers the machine. The current remains constant throughout the coil at about 15 amps, except at high frequencies, such as those over 2000.

The amplifer is regulated by the Instek SFG2004 frequency generator, which is supplied with your machine.

Also included is a voltmeter needed to measure voltage when the coil machine is running. It is important to monitor voltage during use to protect yourself and the machine.

A coil machine is very easy to setup and operate.  Five wires exiting the back of the cabinet are attached to the back of the amplifier and the signal generator. 

The only tool required is a # 1 or #2 Phillips screwdriver.

All directions for setup and operation are included. If you find that you have difficulty in setting the machine up, please give us a call. We provide unlimited phone and email support.
