ABSTRACT:
A clamp assembly includes a yoke having a rectangular configuration and circumscribes a rectangular space, and a pair of spaced electrically conductive terminal bodies mounted in the rectangular space of the yoke. The terminal bodies are adapted to be connected to corresponding electrical terminals of an induction heating machine. A clamp pad is slidably mounted in the rectangular space of the yoke and is moveable vertically toward and away from the tops of the terminal bodies. An induction coil assembly including a hollow induction coil and a pair of spaced parallel elongated terminal bars is provided, with the terminal bars removably clamped between the clamp pad and the tops of the terminal bodies. Each of the terminal bodies contains a side port and a hollow valve stem which protrudes through its top in alignment with a port in a corresponding one of the terminal bars and contains a port aligned with the corresponding side port only when the terminal bars are clamped against the tops of the terminal bodies, thereby enabling coolant to flow into the side port of one terminal body and circulate through the induction coil and out of the side port of the other terminal body. An indicator may be mounted in the clamp pad to indicate when coolant is flowing and when it is safe to activate the assembly.
