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.
• 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: The lower operating temperature allows for increased current capacity, enhancing the efficiency and effectiveness of the welding process.
• Improved Arc Stability: E3 electrodes provide a stable and focused arc, which is crucial for consistent welding results and minimising issues like arc wander.
