Bossweld zirconated Tungsten Electrodes, 1.6mm

Bossweld Zirconated Tungsten Electrodes are polished, white-tipped electrodes made for AC TIG welding, supplied in packs of 10 at 178mm long in 1.6, 2.4 and 3.2mm diameters. They hold a balled tip well under AC, which keeps tungsten transfer into the weld low and gives a steadier arc than pure tungsten, particularly at high AC current.

Aluminium welding is the main use, and the electrodes resist contamination well under AC. They are not a general DC electrode, so choose thoriated, ceriated or lanthanated tungsten for DC work.

Where this product is used

• AC TIG welding of aluminium
• High-current AC welding where the tip has to hold its ball
• Welds where tungsten contamination has to be kept low

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.
