Tungsten Electrodes, Diameter, 0.020", Length, 7", ISO Colour Chart, Red AWS A5.12 EWTh-2 ISO 6848 WT20, Sold/Priced Per, Pack
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; 2% Thoriated:
- Good current capacity, arc stability and easy arc start on DC current
- High resistance to weld pool contamination
- Maintains sharpened tip configuration
- Not normally used on AC current because it is difficult to maintain the balled end
- Medium tendency to spit
- Medium erosion rate;
