PRINCIPLES OF OPERATION
The power cord (3) shall be plugged into a GFI protected outlet that provides 230 VAC - 50-60 Hz. The tool can draw up
to 5 amps during operation. Inside the tool is a power supply and inverter that converts the AC line voltage to a high
frequency output for induction heating of ferrous materials.
The tool accommodates a number of accessories for different applications. They include work coils of various lengths,
diameters and configurations.
There are Preformed Coils (5), U-Form Coils (7), Bearing Buddy Coils (6) or a Mini-Pad (8) that can be attached to the tool
by inserting into the end of tool and then secured to the electrodes using the Twist-Lock™ (11).
Pressing the activation switch (9) will activate the inverter operating the tool. A status indicator LED (14) illuminates GREEN
to designate proper operation. The status indicator LED (14) will illuminate RED if the work coil in not properly installed or
broken. It will also indicate an over temperature condition in the tool when lit RED.
The work coil operates by electromagnetically coupling energy to the object in the field of the coil. This energy heats any
metal by eddy currents (also called Foucault currents). There is also heating by the action of magnetic hysteresis losses of
a ferrous material. The more easily a material is magnetized the more effective the tool is for heating.
The HAND-DUCTION heats ferrous materials and their alloys readily, but has no effect on glass, plastic, wood, cloth and
any other non-conductive material.
The HAND-DUCTION has an illumination LED (12) activated by a slide switch (13) located just above the activation switch
(9). The activation switch (9) activates the inverter when actuated and operates independently from the slide switch (13).
There is a fan that operates to cool the electronics in the tool. The fan will continue to operate after the activation switch
is released until it cools down.
PREPARATION FOR USE
A. Generator & Inverter Use
The HAND-DUCTION is designed to operate from a normal 230 volt alternating current (VAC),
50 or 60 Hz (cycles per second) power line or service outlet, and will operate without suffering
damage on voltages between 207 and 253.
1. Generator: Some portable generators, particularly low-cost units producing 4 kW or less, are unregulated and can
produce in excess of 260 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 HAND-DUCTION, have a professional electrical
contractor measure the generator voltage with a digital voltmeter. Measure the voltage with the generator engine
warm and no load. Some generators, the voltage may be reduced by decreasing the engine speed.
2. Inverter: DC to AC Inverter operation; Use only 1.8 kW (Prosine™1800 is recommended) or larger sine wave
inverter. The use of square or quasi-sine wave inverter will void the warranty.
