ITEM NAME:10pcs WT20 Tungsten Electrode Welding Rod for Argon Arc Welding (1.6x150mm) Product Description Description: Features: Thorium tungsten electrode has large current load, easy arc starting, stable arc, large gap of arc breaking. Low loss, long service life, higher recrystallization temperature and better conductivity. Thorium tungsten electrode is widely used for welding stainless steel/carbon steel/copper/iron/nickel and other metals. Especially if the working current is above 200A, except for welded aluminum. Red tip thorium tungsten is recommended. The grey head dissipates quickly under large electric current, affecting the welding effect. Specifications: Material: thorium tungsten Color: red Core diameter: 1.6 (mm) Type: thorium tungsten electrode (WT20) Drug skin properties: tungsten Welding current :15(-500) Length :150(mm) Specification: 1.6x150mm Notes: 1.
