The Kramp WP10016 is a pack of 10 high-quality WL20 lanthanated tungsten electrodes, specifically designed for TIG (Tungsten Inert Gas) welding applications. These electrodes have a diameter of 1.6 mm and a length of 175 mm. WL20 electrodes, containing 2% lanthanum oxide, offer excellent arc starting, stability, and a longer lifespan compared to thoriated electrodes, making them a versatile choice for both AC and DC welding of various materials including stainless steel, aluminum, and titanium. They are known for their non-radioactive properties and good re-ignition characteristics.
