10pcs 4.0mmx175mm Green Tig Welding Tungsten Electrodes for Aluminium Titanium

Note: The color of the item may vary slightly due to photography and your own computerFeatures:The tungsten electrode does not increase any rare earth,the electron emission ability is smallest,therefore it only suits to alternating current under the big load condition welding,like aluminum and aluminum magnesium alloy welding and so on.Pure tungsten has a very high electron work function, so compared to other alloys of tungsten electrodes, the electrodes from pure tungsten arc harder, maintaining the stability of the arc beam more difficult.In addition, due to the high electron work function, the higher the temperature of the electrode tip and prone to grain growth, which will lead to an unstable arc beam, arcing harder, but life is also shorter.Specifications:Material:TungstenColor:Silver and GreenModel:WpSize:175x 4.0mm/5.91 x 0.09"(L x Dia)window.adminAccountId=221621613.Item specifics:Model number: OEMApplication: 4.0mmx175mm

• The tungsten electrode does not increase any rare earth,the electron emission ability is smallest,therefore it only suits to alternating current under the big load condition welding,like aluminum and aluminum magnesium alloy welding and so on.
• Pure tungsten has a very high electron work function, so compared to other alloys of tungsten electrodes, the electrodes from pure tungsten arc harder, maintaining the stability of the arc beam more difficult.
• In addition, due to the high electron work function, the higher the temperature of the electrode tip and prone to grain growth, which will lead to an unstable arc beam, arcing harder, but life is also shorter.
