III. PRINCIPLES OF OPERATLON
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.
IV. PREPARATION FOR USE
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.
- 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.
VI. USING THE U-FORM COIL tm
Function: The U-Form Coil can be shaped to perform any of the
previous coils jobs, custom part removal, and Hail/Soft dent
- 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
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
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
VII.USIG THE BEARING BUDDY COIL tm
Function: The Bearing Buddy Coil TM (8) is used to free a race from
an axle housing, frozen O2 Sensors, remove ball joints, &
- 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
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
- 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
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
IX. Trouble Shooting
1.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.
