WT20 Tungsten electrode bar

Black or ground electrode of thoriated Tungsten, Cerated, tungsten, Lanthanated Tungsten,

Ziraconiated Tungsten, Pure Tungsten.

 

Applicable Scope:

 

Electroce for Tig Welding and plasma welding, cutting, spray-coating and smelting

 

WT20 Tungsten electrode  Features:

 

WT20 Tungsten electrode :High melting point, low arc ignition, good arc stability, non-consumable. Tungsten

electrode added 0.15-4% ThO2, CeO2, La2O3, ZrO2, which can reduce the burn-off

rate of electrode, prolong its service life, not pollute the welding seam, increase launching

ability of Tungsten electrode electrons with excellent welding appearance and quality.
