Tungsten E3 Purple

Tungsten E3 Purple

E3® – the ultimate, long life tungsten electrodes –the future for TIG welding

More details

TIG electrodes E3® (developed by ABICOR BINZEL® – alloy:rare earth) promote best practice for TIG welding – without radio active doping.


The advantages at a glance:

■ The welder is no longer exposed to radiation.

■ Reduced environmental impact. Remaining pieces and grinding dust are no longer treated as hazardous.

■ No special safeguards required for storage and transport.


All tungsten electrodes are manufactured in accordance with EN ISO 6848.They are produced in-house and imported taking into account all customs duties.Every packet carries a LOT number. Declaration of conformity and safety datasheet freely available, just ask.

Non-radioactive alternatives

E3®*  dfvdfsdfsdfsdffdf             

Electrodes with rare earth (mixed oxides). In comparison to thoriated electrodes this electrode is less harmfulto the environment and not radioactive. The electrodes offer excellent ignition characteristics and consistentwelding properties. They are universal and suitable for all applications in the whole range of DC and ACwelding for non-alloyed and high-alloyed steel, aluminium, titanium, nickel, copper and magnesium alloys. Becauseof their great ignition properties they are also suitable for automated welding. Due to the low electrode temperature, they offer an increased current carrying capacity and longer service life than thoriated electrodes.Colour-coding:

 WLa 10/15/20                                        

Lanthanated electrodes are suitable for applications in DC and AC welding. Their main areas of applicationare the welding of non-alloyed and high-alloyed steel, aluminium, titanium, nickel, copper and magnesium alloys. These electrodes are also suitable for the use in micro-plasma welding. Ignition characteristics are enhanced with increased amounts of lanthanum oxide (La2O3). The overall servicelife and current carrying capacity is lower than the E3® electrodes.Colour-coding:

WLa 10 = black / WLa 15 = gold / WLa 20 = blue 

 WCe 20

By adding cerium oxide (CeO2), these electrodes have an increased capacity compared to pure tungsten electrodes, however the WCe electrodes have a lower capacity than the E3® and WL electrodes. Main areasof application are in the DC and AC welding of non-alloyed and high-alloyed steel, aluminium, titanium,nickel, copper and magnesium alloys in the low and middle current range.Colour-coding:

WCe 20 = grey 

WZr 08 

Tungsten electrodes with the addition of zirconium have a lower risk of contaminating the weld from deposits of tungsten. The main area of application for this electrode is AC welding. They are limited in their suitability for DC welding.Colour-coding:

WZr 08 = white 


The advantages of E3® are self-evident:

■■ Electrode tip remains “cooler” than thoriated types

■■ Superior repeatable ignition characteristics

■■ Increased arc stability

■■ Reduced burn off

■■ Higher current carrying capacity

■■ Lower degradation to the electrode tip

■■ Increased application flexibility
