SÜA - 2% Lanthanated Tungsten Electrode - TIG - 0.04" x 7" - Blue - (10 PACK)

Blue tip 2% lanthanated tungsten electrodes are very popular for general use due to the ease of striking an arc and lower amperage required. They perform exceptionally well in both AC & DC applications. They provide longer lifetime than WT electrodes and no tendency towards slagging.Recommended for:• Aluminum Alloys• Carbon Steel• Stainless Steel• Low Alloy Steels• Copper Alloys• Nickel Alloys• Titanium Alloys• Magnesium AlloysTungsten Electrodes for TIG welding: Tungsten electrodes are used when arc welding with the Tungsten Inert gas (TIG) process or when plasma welding. In both processes the electrode, arc and weld pool are protected from atmospheric contamination by an inert gas. A tungsten electrode is used because it can withstand very high temperatures with minimal melting or erosion. Tungsten electrodes are made by powder metallurgy and are formed to size after sintering. TIG welding tungsten electrodes usually contain small quantities of other metallic oxides which can offer the following benefits:- facilitate arc starting increase arc stability improve current-carrying capacity of the rod. reduce the risk of weld contamination increase electrode life
