TIG welding electrodes engineered for stable arc starts and consistent weld quality. Confidence on the bench when working with stainless, titanium or nickel alloys. Are Kingsrey TIG Welding Tungsten Electrodes WL20 the practical thorium-free choice for hobbyists and professional fabricators?
⚡ At a Glance
- • Welding Performance: Concentrated arc, fast low-current starts and stable welding output
- • Best for: Workshops and fabricators needing reliable TIG starts across many metals
- • Not ideal for: Users who insist on thorium tungsten rather than a lanthanum substitute
2% lanthanum WL20 tungsten electrodes supplied as 1.0mm x 175mm rods with blue-dipped ends. Suitable for AC and DC TIG welding across carbon steel, stainless steel, nickel, titanium, aluminium and copper alloys.
Quicker arc starts and steadier strikes – with 2% lanthanum WL20 composition
2% lanthanum alloy enhances electrical conductivity and supports faster arc initiation at low current, yielding a more concentrated and stable arc.
Faster strikes reduce missed starts and make welding thin sections or low-amperage work more predictable and less prone to rework.
Broad metal compatibility – with AC and DC suitability
Suitable for both DC and AC conditions and compatible with carbon steel, stainless steel, nickel and nickel alloys, titanium, aluminium and copper alloys.
Switch seamlessly between materials on mixed jobs without changing electrode chemistry, useful for repair shops and multi-material fabrication.
Longer tip life and reduced contamination – thanks to low combustion rate and improved recrystallisation properties
Lower combustion rate and reduced cutting-edge corrosion deliver better mechanical cutting performance, higher recrystallisation temperature and improved ductility.
Tips maintain shape for longer, cutting downtime and helping to produce consistent bead profiles over extended use.
