NP550-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; 2% Ceriated:
• Excellent arc starting, stability, long life and higher-current capacity than thoriated tungsten
• Operate successfully with AC or DC current
• Non-radioactive
• Low erosion rate
• Wide current range
• No spitting;
