GYS Professional Quality Tungsten TIG Welding Electrodes (Pkt 10) WL20 Lanthanum (Blue tip) - 4mm diameter

Lanthanum Tungsten electrodes (Blue tip) are universal TIG electrodes that can be used for both direct (DC) and alternating current (AC) and are particularly recommended for welding pure materials or alloys such as Aluminium, Titanium, Nickel, Copper and Magnesium. The higher level of Lanthanum oxide (2%) in their composition optimizes their resistance and priming qualities for an ever more professional look. They are recommended for low currents.
