PORTABLE ELECTROMAGNETIC INDUCTION HEATING DEVICE

摘要

A portable electromagnetic induction heating device which is used to heat an adhesive with a conductor heated by Joule heat produced by running an induction current to the conductor. A heating induction coil (13a) is formed of a plurality of coil elements (21-24, 51-54), and mutual center-to-center distances of respective coil elements can be changed and any one polarity is changed to thereby change the polarity and position of a magnetic force line produced in the conductor, whereby the heating condition of an adhesive can be varied according to the area of the adhesive.
