1.5% Lanthanum Tungsten Electrodes (10 Pack)

These Gold-tip Lanthanated Tungsten TIG Electrodes give welders a reliable, high-performance option for TIG welding across a variety of metals — from mild steel to stainless and alloyed materials. Designed for both AC and DC applications, lanthanated tungsten offers easy arc start, stable arc performance, low burn-off and long electrode life — making it a strong choice whether you’re doing light fabrication, detailed sheet work or heavier TIG projects.

Offered in multiple sizes, you can select the electrode diameter that suits your job — ensuring you always have the right tungsten for thin sheet metal, pipe work, structural TIG or precision welding.

Complies to ANSI/AWS A5 12-92 - BS EN 150 6848:2015

Key Features

Non-radioactive Lanthanated Tungsten — Free from thorium or other radioactive materials; safer for day-to-day use while still delivering high performance.

Excellent Arc Stability & Easy Start (AC/DC) — The lanthanum-doped alloy provides a stable, concentrated arc with good re-ignition characteristics — ideal for both AC and DC TIG welding.

Low Burn-Off & Long Tip Life — Compared with pure tungsten, lanthanated tungsten resists erosion and maintains a sharp tip longer — meaning fewer re-grinds and more consistent welds.

Versatile Across Materials & Thicknesses — Works well on mild steel, stainless steel, aluminium, alloys, thin sheet metal or thicker sections, depending on selected electrode size — giving you flexibility across projects.

Pack Variety & Flexibility — Supplied in packs, with a choice of diameters so you can match tungsten size to your TIG torch, material thickness and welding current, giving better control and weld quality.
