Pure tungsten contains a minimum of 99.8% tungsten with no other alloying elements.
This allows the tip to form a clean, balled end which provides good arc stability on AC. It is generally used in the welding of aluminum and magnesium alloys (AC)
Diameter:1.6/2.0/2.4/3.0/3.2/4.0/4.8mm Length:150/175mm
