Product Details
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; LAYZR ™:
Non-radioactive
Best for automated or robotic applicationss in A/C or D/C due to low voltage tolerance (changes in tip to work piece distance) 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
Very stable tip geometry runs cooler than 2% thoriated, longer life
Very best low amperage starts
