14,Thumb Screw



The power cord ,when connected to a GFI outlet, (11) insures a properly grounded 220 VAC power input connection .The inverter (1) steps up ordinary 220 volt, 60 Hz alternating line current. A work coil, the Bearing Buddy Coil (8), U-Form Coil (9),Preformed Coil (7), or Mini-Pad (10),is inserted into the end of the electrodes (13) and then secured into place with the thumb screws (14),The coil then converts the current to a high frequency alternating magnetic field .This magnetic field crosses the metallic, conductive work surface (e. g, the frozen nut) and vibrates the electrons in the metal through the principle of electromagnetic induction. The kinetic energy of the moving electrons is dissipated as heat ,which warns whatever metal is within the tool’s working range. The more easily magnetized a substance is, the greater the heat developed in it. That is why the apparatus heats ferrous metals and their alloys readily, but has no effect on glass, plastics wood, cloth and other non-conductive materials. The power switch (12) is used to turn the inverter on and off. Push it in to turn on power to the unit. The unit will remain ON as long as pressure is applied to the switch, Remove pressure from the switch to turn the power OFF. Record the serial number from the serial number plate (2) on the

inverter to the enclosed Warranty Card and mail.


Read and understand all safety warnings and cautions in this manual before operating the operating the apparatus
A. Generator & Inverter Use

The apparatus is designed to operate from a-normal 220 volt alternating current (VAC),50 or 60 Hz (cycles per second )power line or service outlet, and will operate with out suffering damage on voltages up to 230 VAC.

1. Generator :Some portable generators, particularly low-cost units producing 4 kW or less, are unregulated and can produce in excess of 240 VAC which will damage the unit and void the warranty . If you are in doubt concerning the electrical generator that will be supplying power to the apparatus , have a professional electrical contractor measure the generator engine warm and no load .

2. Inverter: DC to AC Inverter operation; Use only 1.8 kw ( Prosine TM 1800 is recommended) or larger sine wave inverter. The use of square or quasi-sine wave inverter will void the warranty. Call Induction Innovations, before using your apparatus for instructions on how to proceed if you have any questions regarding the instructions furnished above.


V. Using the Preformed Coil TM

Function: The Preformed Coil TM(7) is used to heat nuts, fasteners, caulking removal, frozen door hinges, exhaust manifold bolts, truck under bed bolts, Sensors (O2)etc.

The life of the Preformed Coil TM can be extended by only heating will eventually burn through when holding directly to hot nuts.

  1. Loosening Corroded, Rusted and "Frozen" Nuts and Bolts<3/4"

Step 1 Perform the "Preparation for Use " instructions.

Step 2 Push the power switch to activate the Apparatus.

Step 3 Bring the Preformed Coil tm around the frozen nut, with a wrench or socket. If it is still frozen, apply the Preformed Coil tm for another two seconds. And then try the wrench again. There is usually no reason to heat a nut to a red-hot condition in order to free it from the corrosion holding it the bolt.


Function: The U-Form Coil can be shaped to perform any of the previous coils jobs, custom part removal, and Hail/Soft dent removal.

  1. Loosening Corroded, Rusted and "Frozen" Nuts and Bolts > 3/4 "

Step 1 Perform the "Preparation for Use" instructions.

Step 2 Configure the coil to the size nut by wapping it around a socket piece for that nut .

Tip: The more coil winds you can get the faster it will heat.

Step 3 Insert both ends of the U-Form coil into the electrodes and tighten thumb screws.

Step 4 Bring the U-form TM Coil around the frozen nut, initially for only two seconds, back it away, and try to remove the nut with a wrench or socket. If it is still frozen, apply the U-Form Coil TM for another two seconds. And then try condition in order to free it from the corrosion holding it to the bolt.

B. Heat Shrinking Hail / Soft Dents in Sheet Metal

Step 1 Perform the "Preparation for Use " instructions.

Step 2 Configure the Coil to look like the diagram on the right .

Step 3 Holding the U-form coil 1/2 to 1 inch above a dent, move it

in a small circular motion and gradually bring it closer to the dent,

but keeping it around the outside of the crown of the dent. As soon

as the dent shrinks, back the U-Form Coil away quickly and cool

the treating dent with a damp rag. If the dent sucks in you are

heating the crown or not far enough around the outside of the

crown. Repeat the procedure until removed completely.

Tip: Once a puff of smoke releases from the dent immediately remove the U-Form Coil from the area. This is the point at which the paint will start to bubble. Also be careful on white and light colored finishes, these lighter paints tend to yellow sooner than darker colors.

Trouble Shooting: If the dent doesn't seem to want to shrink, this may be because there is a crease in the metal or the metal has been stretched to far.


Function: The Bearing Buddy Coil TM (8) is used to free a race from an axle housing, frozen O2 Sensors, remove ball joints, & tie-roc ends.

  1. Expanding a piece to remove an interlocking part

Step 1 Perform the "Preparation for Use" instructions.

Step 2 Insert one end of the Bearing Buddy Coil into one of the electrodes and tighten thumb screw.

Step 3 Wrap the coil at least 3 times around the work piece to be expanded.

Tip: The more coil winds you have the faster it will heat.

Step 4 Insert the other end into the remaining open electrode and tighten the thumb screw.

Step 5 Push the power switch to activate the apparatus

Step 6 Heat until expanded enough to remove the race.

Step 7 Release the power switch and loosen both thumbscrews to remove the Bearing Buddy Coil.

VIII. USING THE MINI-PAD tm(optional )

Function: The Mini-Pad TM (10) is used for removing stickers, decals, graphics, emblems, small body side moldings, and pin striping.

  1. Removing Bonded on parts.

Step 1 Perform the "Preparation for Use" instructions.

Step 2 Insert both Mini-Pad ends into the electrodes and right thumb screws.

Step 3 Push the power switch to activate the apparatus.

Step 4 Apply the Mini-Pad to the end of the desired part to be removed for a couple seconds. Once you are able to peel the start of the part off, you will have an area you can pull on to keep outward pressures going. Re-apply the Mini-Pad to the part , working it down the part while keeping outward pressure until the part is completely removed.

IX. Trouble Shooting
The Apparatus R inverter is designed to stop running if overheated, however, the electrodes DO NOT have an overheat shutoff. This is why there is a duty cycle with the apparatus Two minutes on two minutes off. If the unit stops suddenly; check to insure unit is still plugged into a functioning AC power outlet. Also be sure if using an extension cord that there are no cuts in the cord, Allow the unit to cool off for at least 30 minutes and then restart. If problems persist call Induction Innovations,

1.If there is a lack of power output, this may be from using an improper extension cord or a damaged attachment. The proper gauge and length cord is 25 ft. 14-AWG or 50-ft, 12-AWG. Do not use more than one extension cord at once.

1. For other problems contact Induction Innovations,

X. Disassembly and Storage

Turn unit off and allow the unit and all working coils to cool for at least 30 minutes before disassembly, cleaning or storage. Handling the unit or parts before they have cooled may result in injury; storage of unit while still hot may result in damage to equipment or pose a fire hazard.

Step 1 When you are finished working, turn the power OFF by releasing the power switch and make sure that the internal fan stops.

Step 2 Disconnect the plug(11)from the service outlet or extension cord.

Step 3 place unit and coils into foam cutouts in storage case.
