Bossweld technology 2% Thoriated Tungsten Electrodes, 1.6mm

Bossweld Technology 2% Thoriated Tungsten Electrodes are polished, red-tipped electrodes for DC TIG welding, supplied in packs of 10 at 178mm long. Thoriated is the most widely used tungsten type, with the thorium oxide spread evenly through the whole length of the electrode for easier arc starting and a more stable arc.

They are used on DC electrode negative (straight polarity) for carbon and stainless steels, nickel alloys and titanium. Thoriated tungsten contains thorium oxide, which is weakly radioactive.

Key specifications

Choosing the right option

Pick the diameter from your welding current and joint, and check that your torch collet and collet body match it. Smaller diameters suit lower current on thinner material, and larger diameters carry more current. Grind the tip to a taper with the grinding marks running along the length of the electrode, and use a wheel kept for tungsten only so the tip stays clean. The 1.0, 3.2 and 4.0mm sizes separately as the Bossweld 2% Thoriated Tungsten Electrodes 900308.

Other tungsten types: Bossweld 2% Thoriated Tungsten Electrodes 900308, Bossweld Ceriated Tungsten Electrodes 900330, Bossweld Zirconated Tungsten Electrodes 900320.
