Tungsten electrodes GRADIENT WL20 Ø3.2x175 mm

• have low level of contamination of welded joints • durable • are characterized by a small tendency to fire metal • Fast arson arc The tungsten alloy with lantan oxide have a slight initial start of the arc, a low tendency to fire metal, as well as a stable arc and excellent characteristics of re -setting the arc. In the Electrode WL -20 Lite L - indicates the content of the lantan, the number 20 indicates 2.0% of the lantane oxide, which, in turn, provides an increase in maximum current. Tungsten electrodes with Lantan oxide (WL) have a longer life span and less slag with tungsten welded seam. This is certainly a significant advantage of welding on DC (direct polarity) or AC from improved sources of welding current, various carbon steels and stainless steels. Application: • for welding all types of steels and alloys • on DC and AC (AC/DC) DIN EN 26848 marking: • WL-20 Products Certified: • ISO6848-2004 The color of the working edge of the electrode: • sky-blue
