Tungsten Electrodes - T187G

MPN: T187G

• 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; Pure:
• Lowest current capacity and least expensive
• Maintains a clean balled end for welding on AC
• More prone to weld contamination than other types of tungsten electrodes
• Tends to spit at higher currents
• Used for non-critical welds only
