Tungstens

Tungsten electrodes are vital TIG welding consumables, providing stable arc performance, clean starts and consistent weld control across a range of materials. Each tungsten type is colour coded for quick identification, with different compositions optimised for AC, DC, low amperage, or multi process applications. The table below shows all major tungsten types, their colour codes, composition and typical uses to help you select the correct electrode for your welding task.

Tungsten electrodes are colour coded to clearly identify their alloy composition and welding characteristics. Each type offers unique performance for AC, DC, high amperage or precision low amperage TIG welding. The following table provides a concise, professional overview of all major tungsten electrode types.

Tip Colour	Type	Best For
Black	Lanthanum (1%)	AC & DC – general purpose
Blue	Lanthanum (2%)	AC & DC – premium all round tungsten
Gold	Lanthanum (1.5%)	AC & DC – popular all rounder
Green	Pure	AC welding, aluminium
Grey	Ceriated (2%)	Low amp DC, thin materials
Purple	E3	AC & DC – long life hybrid
Red	Thoriated (2%)	DC welding on steels & stainless
White	Zirconiated (0.8%)	AC welding on aluminium
