Turquoise tungsten electrode WR02 - the universal MMA electrode for precise and clean TIG welding
If you value clean ignitions, stable arcs and even welding seams when Arcs and even welding seams, there is no way around the turquoise tungsten electrode WR02 tungsten electrode. It is a modern, radiation-free alternative to the previously popular but radioactive thorium electrodes Thorium electrodes and impresses with maximum versatility - no matter whether you want to weld steel, stainless steel or aluminium.

What makes the WR02 so special?
The WR02, also known as the EWG or WSa 2 is one of the most modern tungsten electrodes in its class. Its secret lies in the precise doping with 2 % mixed oxides of Rare earths - usually lanthanum oxide and cerium oxide. This Combination ensures particularly efficient electron emission, the arc ignites more easily, runs more smoothly and the electrode MMA achieves a significantly longer service life.
This means for you:
-
Easier ignition - even at low amperage.
-
Greater arc stability - for perfect control.
-
Less burn-up - less consumption, longer service life.
Especially in series production or automated welding processes this pays off: The WR02 saves time, reduces downtimes and ensures consistent welding quality - a real productivity gain.
Safety and the environment - welding without risk
Another decisive advantage: The WR02 is completely radiation-free radiation-free. In contrast to older thoriated MMA (WT20, red), it does not contain any thorium. You therefore do not need any special Protective measures during storage, grinding or disposal.
This makes the WR02 a true pioneer of modern "green Welding " - environmentally friendly, safe and powerful at the same time.
-
No radioactive additives
-
No hazardous waste during grinding or disposal
-
No health hazards during operation
So you can weld with a clear conscience - safely, cleanly and sustainable.
Universal use - AC and DC perfectly under control
Whether direct current (DC) or alternating current (AC) - the turquoise MMA WR02 is optimised for both types of current:
-
DC welding (direct current): Ideal for steel, stainless steel (INOX), Copper, titanium or nickel. Here, the WR02 delivers a focussed arc Arc with deep penetration - perfect for narrow, precise seams.
-
AC welding (alternating current): Indispensable for aluminium and magnesium indispensable. In AC operation, the WR02 forms a uniform Which keeps the arc stable and prevents inclusions in the weld pool And avoids inclusionsin the weld pool.
This saves you having to constantly change different MMAs - the the WR02 is the real all-rounder among tungsten electrodes.
Technical strength meets user-friendliness
The WR02 is available in many diameters - from 1.0** mm for ultra-fine work up to 6.4** mm for high-current applications. For 2.4 mm is the perfect all-round size for most projects.
Whether you work in car body construction, pipeline construction or in the aerospace industry Aerospace - wherever arc stability and welding quality Arc stability andwelding quality count, the WR02 is the right choice.
Typical areas of application:
-
Steel and stainless steel: Deep penetration, stable seams in DC operation.
-
Aluminium and magnesium: Clean, spatter-free seams thanks to regular calotte formation.
-
Titanium, nickel, copper: Precise control with reactive metals.
-
Thin sheet welding: Stable even at 10-30 amps - ideal for precision work Precision work.
Perfect control through correct grinding
For the WR02 to realise its full potential, preparation plays an important role plays an important role.
-
For DC welding (e.g. steel, stainless steel): Taper the tip (approx. 30-60°). This keeps the arc focussed and the penetration the penetration deep.
-
For AC welding (e.g. aluminium): Slightly round off thetip or let the current itself shape the tip into a spherical cap - this ensures arc and even heat distribution.
Important: Always grind lengthwise to the MMA - never crosswise! Crosswise tips lead to an unstable arc and faster wear Wear.
Productivity and economy
The WR02 is a real efficiency booster for commercial users:
-
Fewer electrode changes as it burns off more slowly.
-
Less grinding work thanks to long service life.
-
High process reliability, especially in automated Welding systems.
Thanks to its standardised production in accordance with DIN EN ISO 6848 and ANSI/AWS A5.12, it is compatible worldwide and reliable in terms of quality and dimensional Dimensional accuracy. This simplifies stock-keeping - one electrode for MMA for almost all applications.
Application tips for beginners
The WR02 is particularly useful when starting out with TIG welding grateful. Its easy ignition behaviour forgives small mistakes made by beginners, and the smooth arc makes it easier to practise even seams.
Tip: Start with 3-5 mm thick sheet steel to get a feel for the arc Arc, the weld pool and the filler wire before you start working with thin or You venture into thin or sensitive materials.
Conclusion: One MMA for all occasions
The turquoise WR02 tungsten electrode is the new benchmark for professional and ambitious TIG welding.
It combines ignition reliability, arc stability, durability, Versatility and environmental compatibility - all in a single electrode MMA.
Whether you are welding aluminium, steel or stainless steel: With the WR02 you get a universal MMA electrode that can do it all - precisely, safely and efficiently.
