WCe20 (EWCe-2) Grey Tip
Products Name :Ceriated Tungsten electrodes
Products Features:This material good for low-amp, DC orbital tube, pipe, thin sheet, and small part applications, this formula offers low current capacity, low arc ignition, good arc stability and is non-radioactive.
Products Application: Stainless steels、pipeline and small precision parts welding.
WLa15/20 (EWLa-1.5/2)Gold/blue Tip
Products Name :Lanthanated Tungsten electrodes
Products Features:This material is a good general purpose non-radioactive replacement for 2% Thoriated. It has excellent ignition performance, low-burn-off rate, excellent re-ignition, and good service life.
Products Application: Stainless steels、Carbon steel、Nickel、Titanium、Copper、Magnesium、Aluminum and its alloys
WZr8(EWZr-0.8) White Tip
Products Name : Zirconiated Tungsten electrodes
Products Features: Used for radiographic-quality welding where tungsten contamination must be minimized. Balls-up easily in AC applications, good arc starting and current capacity.
Products Application: Magnesium、Aluminum and its alloys
WP (EWP) Green Tip
Products Name :Pure Tungsten electrodes
Products Features:Pure tungsten has a high work-function which makes it diffi cult to start and maintain a stable arc. High burn-off rate results in short service life.
Products Application: Magnesium、Aluminum and its alloys
WS2 /WE3 (EWG) Turquoise Tip
Products Name : Compound Tungsten electrodes
Products Features: This material is the newest alternative to WT20 as green products.
Products Application: Stainless steels、Carbon steel、Nickel、Titanium、Copper、Magnesium、Aluminum and its alloys.
