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.
Claims13
A hot wire welder comprising at least two longitudinal tubes, each tube being adapted to carry a respective welding wire, a longitudinal buss bar for each tube operable to carry power and apply it to said welding wires adjacent the welding area, a guide holder adapted to hold said tubes, a backing block spaced from said guide holder towards said welding area in contact with said welding wires and drive means to drive said wire through said tubes, said guide holder and backing block being connected to a cooling block cooled by water circulating within said cooling block.
A hot wire welder comprising at least two longitudinal tubes, each tube being adapted to carry a respective welding wire, a longitudinal buss bar for each tube operable to carry power and apply it through a replaceable copper insert positioned between a respective one of said welding wires and said respective buss bar, each of said welding wires running between said copper inserts and a ceramic insert, each of said welding wires being separated from an adjacent welding wire by part of said ceramic insert, said buss bars being operable to apply pressure on said welding wire and being pivotably connected to a frame, said buss bars having pressure applied on the end of said frame opposed to said end applying pressure on said welding wire.
