714-1185-Tungsten Electrodes

• 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; 0.8% Zirconiated:
• Excellent for AC welding due to the higher arc stability
• High-resistance to weld pool contamination
• Excellent balled end retention
• Handles higher current with less spitting
• Better arc starts and arc stability than pure tungsten;
