10pcs Red Code 150MM Thorium Tungsten Electrode Head Rod Needle/Wire for TIG WSME SUPER Welding Machine(1.0MM)

Specifications: 1.0/1.6/2.0/2.4/3.0/3.2/4.0 (mm)X150mmPackaging: plastic boxQuantity: 10 / boxColor: RedWeight: 0.08KGTIPS:In the Commodity attributes "1. 6" means the Diameter is 1.6MMThe scope of application for the pipes and welding of small parts of the pull intermittent welding and a specific number of welding 1.pure tungsten is the longest history of use of a non-melting electrode. Tungsten's high melting point of about 3390-3430 degrees Celsius the boiling point of about 5900 degrees Celsius. But there are some drawbacks: First the electron emission less able to require that power high-load voltage; anti-burning short service life the need for frequent replacement of the extreme head of the re-grinding of tungsten. Is mainly used in AC welding of aluminum magnesium and its alloys its broken oxide film and good.2.The thorium tungsten in the tungsten in a certain amount of thorium oxide (ThO2) after the thorium tungsten. Electron emission capability the desired arc voltage is low easy and stable arc greatly extend the life of the tungsten. But a trace of radioactive thoria (THO2).3.cerium tungsten in the tungsten in less than 2% of the oxidation of cerium (CeO) made of cerium tungsten. Its main features are: radioactive allowable current increases the hot electron emission ability stable arc the heat concentrated long life the shape of the ends is easy to keep.2.More detail about the tungstenTungsten needle main purposes: for the production of high-intensity gas discharge lamp arc tubes electrode.Due to the nature of the tungsten making it very suitable electrode materials for tiG welding and other similar kind of work. To stimulate the electron work function by adding rare earth oxides in the metal tungsten tungsten electrode welding performance can be improved: the electrode from the arc better performance higher stability of the arc column electrode burning lo
