Tungsten Electrodes – 3/32″, 7″, Gold AWS A5.12 EWLa-1.5 ISO6848 WL15, Pack, 10, 1.5% Lanthanated

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; 1.5% Lanthanated:
• Lowest erosion rate
• Wide current range
• No spitting
• Best DC arc starts and stability;
