Tungsten Electrodes - T187GT2

MPN: T187GT2

• 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;
