Tungsten electrodes WL15 Gold: The universal power pack for TIG professionals

The golden tungsten electrode (WL15) is the undisputed "all-rounder" in modern welding technology. Due to the doping with 1.5 % Lanthanum oxide (La₂O₃), it combines maximum versatility with outstanding ignition properties. Whether for delicate stainless steel work or demanding aluminium welding - the WL15 delivers consistently reproducible results and is the first choice for anyone who does not Who do not want to compromise on quality.

At Schweiss-Shop.de you will find the WL15 in professional quality for stable arcs on almost all metallic materials.

Why no workshop should be without the WL15 Gold

The addition of lanthanum oxide reduces the work function of the electrons significantly. This makes the WL15 the ideal, radiation-free Alternative to the outdated red MMA. Its advantages in practice In practice:

Areas of application: True universality in AC and DC

The WL15 Gold is one of the few MMAs that can be used with both That impresses across the board in both direct current and alternating current:

Professional tip: The perfect cut for gold

For welding in the DC range (steel/stainless steel), the WL15 unfolds its full its full potential with an axial longitudinal cut.

FAQ - Frequently asked questions about the WL15 (gold)

Can the WL15 replace the red WT20 MMA? Yes, the WL15 Gold is the perfect replacement. It offers an equally strong ignition behaviour, but is completely free of radioactive thorium. This makes it safer for your health and easier to dispose of.

What is the difference between WL15 (gold) and WL20 (blue)? The gold MMA has 1.5 % lanthanum oxide, the blue one 2.0 %. In practice the gold WL15 is often a little more universally applicable in the (AC), while the blue WL20 is ideal for extremely high DC loads high direct current loads.

Why is my MMA turning blue? A bluish discolouration after welding usually indicates that the gas post-flow timeis too short too short. The hot tungsten reacts with atmospheric oxygen. Increase the Post-flow time to maximise the service life of your WL15.
