Chain link and joiner heater

摘要

A chain link and joiner link heater and a method for its operation wherein spaced-apart electrodes are provided for supporting a single chain link. Clamp means are utilized for holding the chain link in position on the electrodes with the clamping means being independently operated to permit adjustment of the electrode spacing depending upon the size of the link involved. The structure permits supporting of a link in a manner such that the application of current provides for heating of a link body portion intermediate the ends of the link while avoiding any significant amount of heat at the exposed ends of the link so that subsequent welding operations can be efficiently carried out.
