TIG Tungsten Electrodes
Lanthanum Tungsten
Steel/Stainless/Aluminium
WR2 Tungsten
Steel/Stainless/Aluminium
Tungsten electrodes are used for TIG welding. The melting temperature of tungsten is very high (around
3400°C) to maintain the arc between the workpiece and the electrode without consuming it too quickly.
Several types of electrodes can be chosen depending on the process used. EN26848 and ISO 6848 provide
information on these electrodes.
The Lanthanum Tungsten electrodes (gold) are versatile
TIG electrodes for welding steel and stainless steel in DC
as well as aluminium in AC. The presence of Lanthanum in
the composition gives them a slower wear and consumes
less power while initiating than WR2 electrodes.
The WR2 Tungsten electrodes (turquoise) are versatile TIG
electrodes for welding steel and stainless steel in DC as
well as aluminium in AC.

More information
Sharpening the electrode : The sharpening angle has a
huge impact on the welding performance. A large angle
produces a narrow welding and high penetration while a
small angle produces a wide weld with less penetration.

Summary
Pure Tungsten
Aluminium
The Pure Tungsten electrodes (green) are designed for
welding aluminium in AC. A well formed ball is created at
the end of the electrode, this ball is formed within seconds.
Thus, the Tungsten electrode for this type of welding is not
sharpened.
