Description
- 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
