PORTABLE COILS AND CONDUCTIVE CABLES.

Coils and conductive cables are used to establish a longitudinal Magnetic field within a component. When a preformed coils is used, the component is placed against the inside surface on the coil. Coils typically have three or five turns of a copper cable within the molded frame. A foot switch is often used is typically 00 extra flexible or 0000 extra flexible. The number of wraps is determined by the magnetizing force needed and of course, the length of the cable. Normally, the wraps are kept as close together as possible. When using a coil  or cable wrapped into a coil, amperage is usually expressed in ampere - turns. Ampere - turns is the amperage shown on the amp meter times the number of turns in the coil.
PORTABLE POWER SUPPLIES :- Portable power supplies are used to provide the necessary electricity to the prods, coils or cables. Power supplies are commercially available in a variety of sizes. Small power supplies generally provide up to 1,500A of half - wave direct current or Alternating Current when used with 4.5meter 0000cable. They are small and light enough to be carried and operate on either 120V or 240V electrical service. when more power is necessary, mobile power supplies can be used  These units also operate on 120V or 240V electrical service and can provide up to 6,000A of AC or half - wave DC when 9meters or less of 0000 cable is used
