ABSTRACT:
The invention relates to a hand-held welding device capable of diffusion bonding or welding to compatible metal surfaces a variety of materials including wire, metal strips, component leads, and other suitable metallic objects. The device is formed with a tubular housing in which are mounted an adjustable, outer electrode assembly and an adjustable, inner electrode assembly, the outer electrode assembly being arranged to have interchangeable, contact-probe members, and the inner electrode assembly being positioned coaxially within the outer electrode assembly. Each electrode assembly is spring-biased, the biasing force of each spring being independently adjustable to provide an optimum bonding pressure on the workpiece and the proper engagement of a pressure-sensitive switch to activate the current pulse of a power-supply unit.
