Abstract: An electrical work-in-circuit heating tool for metal bonding especially in cramped locations where flame heating and tong-style tools are not usable. The tool comprises a hinged pair of spring-loaded arms having electrically insulating open-ended handles each of which contains a conductor bar within a grip portion thereof. The hinge comprises pivotally joined radial webs and the spring-loading is adapted to urge the distal ends of the arms toward each other. Each of the conductor bars is connected within an insulating grip portion of the handle to an electrical supply cable. At the distal end, each conductor bar carries a detachable electrode assembly that comprises a workpiece-contact member. A switch which is part of a low voltage power supply is removably mounted on the handle. Various configurations of electrode assembly are provided comprising different workpiece-contact members, such as a carbon block on each conductor bar, or a contact member on one bar and a ground clamp on the other.
