Purple Tip Tungsten Electrode – E3 Rare Earth

Purple Tip Rare Earth Tungsten Electrodes (mixed oxides), in comparison to thoriated electrodes is less harmful to the environment and non-radioactive.

The electrodes offer excellent ignition characteristics and consistent welding properties.

They are universal and suitable for all applications in the whole range of DC and AC welding for non-alloyed and high-alloyed steel, aluminium, titanium, nickel, copper and magnesium alloys.

Because of their great ignition properties they are also suitable for automated welding. Due to the low electrode temperature, they offer an increased current capacity and longer service life than thoriated electrodes.

• Longer lasting
• Non-Radioactive
• Cooler running than Thoriated
• Suitable for most DC applications
• Superior repeatable ignition characteristics
