| The Model 258B Thermocouple welder is a TIG (tungsten-inert gas) Thermocouple welder that operates in conjunction with a bottle of argon gas and a pressure reducing valve. The energy from an electrical arc, flowing through two thermocouple wires, raises the temperature of the two wires to their melting point. At the arc's termination, the molten wires cool to form a perfectly welded thermocouple. Since this is not a gas welder, there is no contamination from a third metal used in making the junction, nor do air-borne particles or gasses contaminate the weld. The two different wire compositions are completely alloyed in the junction. The welding of the thermocouple is done by placing the two wires into the wire holder, inserting the holder into the weld cavity, and pressing the WELD push button. Type J,K T and E along with R/S, and C Thermocouples are welded easily. |
