Huntingdon Fusion Techniques (HFT) MultiStrike Tungsten Electrodes are versatile, providing stable performance for welding steels, alloys (using DC), and aluminum (using AC) within the current range of 0-300 Amps. They outperform conventional 2% thoriated tungsten electrodes by offering up to 10 times the number of arc strikes under the same conditions. These electrodes are non-thoriated, non-radiotoxic, and non-carcinogenic. Additionally, they lower working temperatures, resulting in narrower, lower heat input welds and extending the number of arc strikes before re-grinding is required. Developed with user safety in mind, Techweld MultiStrike Tungsten Electrodes are traceable through batch numbers and come in special packaging. Immediate delivery is available for these electrodes.
