Teledyne EWTH-2 Thoriated Tungsten Electrodes

Description:

The Teledyne EWTH-2 Thoriated Tungsten Electrodes are used in gas tungsten arc welding (GTAW/TIG) applications to provide stable arc performance, excellent arc starting, and high current-carrying capacity for precision welding. Commonly used for welding carbon steel, stainless steel, nickel alloys, titanium, copper alloys, and other non-corrosive metals in industrial fabrication, aerospace manufacturing, power generation, and maintenance operations. Maintenance technicians, certified welders, and fabrication professionals use these electrodes for production welding, equipment repair, fabrication, and replacement of worn TIG welding electrodes.

Applications:

The Teledyne EWTH-2 Thoriated Tungsten Electrodes are commonly used in DC TIG welding systems, aerospace component manufacturing, pressure vessel fabrication, pipeline construction, automotive production, power plant maintenance, metal fabrication shops, and industrial welding operations requiring reliable arc stability, long electrode life, and precise weld quality.
