ABSTRACT:
An induction wire preheater for heating electrical wire includes left and right inductors, each having a longitudinal passageway through which the wire being heated is passed. Both inductors are fixedly mounted on a mounting plate and/are tilted relative to each. A lower wheel is rotatably mounted on the mounting plate below the inductors, and an upper wheel is rotatably mounted on the mounting plate above the inductors. First, second and third auxiliary wheels are also provided. In use, wire enters the preheater from the right, passes under the first auxiliary wheel, over the upper wheel, through the left inductor, under the lower wheel, through the right inductor, over the second auxiliary wheel, over the upper wheel a second time, under the third auxiliary wheel and then exits from the left.
