An electrode for an oxygen plasma arc cutting torch having suppressed double arc generation and improved lifetime

摘要

The present invention relates to an electrode of a plasma arc cutting torch which is widely used for cutting metal, and more particularly, to a plasma arc cutting method using an air, oxygen, or oxygen mixed gas, To an electrode for a plasma arc cutting torch which can stabilize the service life and reduce the rate of occurrence of a double arc.;A plated layer 4 having an appropriate thickness is formed using a material such as silver, gold, platinum and alloys thereof having a high oxidation resistance and a relatively higher work function than the radiation insert 3 on the surface of the electrode body section 5 And is an electrode for an oxygen plasma arc cutting torch having an effect of suppressing generation of double arc and improving lifetime.
