1) Pure tungsten contains a minimum of 99.5% 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)
2) Color mark: WP (green)
3) Other impurity: ≤0.20%
4) Diameter: 1.0 - 12.0mm
5) Length: 50.00, 75.00, 150.00, 175.00mm
