TIG Welder Tungsten Electrodes

Tungsten electrodes are the non-consumable conductors used in TIG welding to establish the electric arc. They are available in various compositions, identified by a colour code on the tip, each suited to different materials and currents. Common types include Thoriated (Red) for DC welding of steel, Zirconiated (White) for AC welding of aluminium, and Lanthanated (Gold or Blue) and Multi-Mix (Purple/Grey) which offer excellent performance on both AC and DC, making them versatile all-rounders.

Selecting the right tungsten is critical for arc starting, stability, and weld quality. For example, modern Multi-Mix tungstens are non-radioactive alternatives to Thoriated tungstens, offering longer life and better ignition properties without the health risks associated with thorium dust. Proper preparation, such as grinding the tip to a point (for DC) or balling it (for AC), is also essential for optimal performance.
