从China供应商批量进口39 Pcs Tig Welding Kit Lanthanum Tungsten

39 pieces tig welding kit lanthanum tungsten electrode for 140-200a. These 39 accessoried include: 4 pcs ceramic nozzles #4 4 pcs ceramic nozzles #5 4 pcs ceramic nozzles #6 4 pcs ceramic nozzles #7 4 pcs ceramic nozzles #8 3 pcs collets ø2.0mm 3 pcs collet bodys ø2.0mm 10 pcs lanthanum electrodes ø2.0*150mm 1 pcs long back cap 1 pcs medium back cap 1 pcs short back cap Lanthanum - tungsten electrode is currently the most popular international electrode materials, especially the content of 1.5% ( with a content of 2% difference ) of lanthanum tungsten electrode. Scientific studies show that, 1.5% lanthanum tungsten has the closest 2% thorium tungsten demonstrated by the conductive performance, therefore, the welding personnel can easily replace the electrode, without changing the parameters of the equipment. In 1998 there was a very famous field test, is the 2% thoriated tungsten electrodes, tungsten electrodes 2% and two manufacturers of 1.5% tungsten electrodes respectively in 70 and 150 amperes of electric current, 300 v dc welding task environment, the fruit is, in these two cases, 1.5% lanthanum tungsten electrodes show the excellent welding performance, at the same time, but also reflects its burn rate of small features. Lanthanum - tungsten electrode is also applied to the ac welding task, and performance.
