Abstract:
An apparatus for the removal of rust and paint from a metal surface by means of induction heat, the apparatus comprising:an electrical power supply means; an induction coil coupled to the power supply means; a wheel which rotates on the metal surface as the apparatus is moved over the metal surface; a tachometer which measures the amount of rotation of the wheel over time, and thus measures the velocity of the apparatus over the metal surface; and a control unit to regulate the power output of the electrical power supply means; wherein said control unit receives rotational measurement signals from said tachometer and regulates the power output of the electrical supply means by increasing the power output as the velocity of the apparatus over the metal surface increases, and decreasing the power output as the velocity of the apparatus over the metal surface decreases.
