CK Worldwide Inc T5327GZ Tungsten Electrodes, 5/32″ Dia. x 7″ L-(Pack of 10)

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; 0.8% Zirconiated:
Excellent for AC welding due to the higher arc stability
High-resistance to weld pool contamination
Excellent balled end retention
Handles higher current with less spitting
Better arc starts and arc stability than pure tungsten;
