Fonctionnalités (Features): TIG welding electrodes usually contain small quantities of metallic oxides which can offer the following benefits: -Facilitate arc starting -Increase arc stability -Improve current carrying capacity of the electrode -Reduce the risk of weld contamination -Increase electrode life Oxides used are primarily zirconium, thorium, lanthanum or cerium Additions are 1% - 4%, improve arc initiation, especially when direct current (DC) welding is employed Thorium oxide (thoria), effective in terms of long life and thermal efficiency Zirconium oxide (zirconia) has been commonly used for alternating (AC) TIG welding, welding aluminum Electrode length: 7" Each package contains 10 electrodes; 2% Thoriated: Good current capacity, arc stability and easy arc start on DC current High resistance to weld pool contamination Maintains sharpened tip configuration Not normally used on AC current because it is difficult to maintain the balled end Medium tendency to spit Medium erosion rate;
