Abstract

A hot wire welder comprises a plurality of longitudinal tubes with welding wire moving through the tubes. At one end, buss bars pass power to the wires as they emerge from the tubes. Replaceable copper inserts are positioned between the wires and the buss bars. A replaceable ceramic insert is positioned below the wire on a water-cooled cooling block to insulate each wire and remove excess heat. A drive device powers the wires through the longitudinal tubes.
