E3 Tungsten Electrodes - The Preferred Alternative: MATHESON Select E3 Tungsten Electrodes deliver superior arc starting, electrode lifetime, and overall cost-effectiveness. Users of 2% thoriated tungsten electrodes can switch to E3 Tungsten Electrodes with confidence.E3 Tungsten Electrodes Can Outperform 2% Thoriated Tungsten Electrodes. MATHESON Select ® E3 Tungsten Electrodes use 1.5% lanthanum oxide (plus other oxides) instead of 2.0% thorium oxide. Because the conductivity of E3 Tungsten Electrodes is similar to that of thoriated tungsten electrodes, the transition to E3 Tungsten Electrodes can normally be made will little or no modification of the welding process itself.Many of the advantages for users of MATHESON Select ® E3 Tungsten Electrodes are reviewed below.
