Tungsten Electrodes - T187GL2

MPN: T187GL2

• 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% Lanthanated:
• Non-radioactive
• Best general purpose electrode at medium to highter amperage for both A/C or D/C using inverter or transformer based constant current power sources
• Good for low-alloyed steels, non corroding steels, aluminum alloys, magnesium alloys, titanium alloys, nickel alloys, and copper alloys
• Good arc starts and stability, low erosion rate, medium to high current range
