Product Description
Whereas black tip lanthanated tungsten electrodes are amazing for maintaining a sharp tip, purple E3 also contain lanthanum, meaning excellent tip retention. This is crucial for precise welding and preventing contamination.
With lanthanum being the primary rare earth element, these have been developed in part to tackle the radioactive thorium of red tip. The E3 is an extremely durable product that allows for extra-long tip life, vastly reduced abrasion, and overall low heat load on the electrode.
They are known for their ease of arc starting, consistent welding properties, stable arc, and longer service life compared to other tungsten types.
- Non-Radioactive: Unlike thoriated tungsten electrodes, Purple E3 electrodes do not contain any radioactive materials, making them safer for both the welder and the environment.
- Non-contamination: Purple E3 tungsten electrodes are known for their resistance to contamination due to their composition and properties (better than red thoriated)
- Excellent Ignition Characteristics: They provide superior ignition and re-ignition capabilities, which is particularly beneficial in applications that require frequent starts and stops.
- Versatile Use: These electrodes are suitable for both AC and DC welding, making them versatile for a wide range of materials, including non-alloyed and high-alloyed steel, aluminium, titanium, nickel, copper, and magnesium alloys.
- Longer Service Life: Purple E3 electrodes tend to have a longer lifespan compared to other types, such as thoriated tungsten, due to their ability to operate at cooler temperatures.
- Increased Current Capacity: Outstanding when used at higher amperage. The lower operating temperature allows for increased current capacity, enhancing the efficiency, effectiveness and control of the welding process.
- Improved Arc Stability: Because E3 electrodes can handle welding current a lot more efficiently than other tungstens (even better than red tip on DC), they provide a stable and focused arc, which is crucial for consistent welding results and minimising issues like arc wander.
