摘要： The present invention relates to a plasma torch having a multi-electrode front electrode and a button-type rear electrode. The present invention allows easy initial discharge by using the button-type rear electrode and an auxiliary electrode for discharge, and easy initial ignition of a high-output arc plasma torch by naturally forming an arc column between the rear electrode and the front electrode even in the absence of smooth discharge between the rear electrode and the auxiliary electrode for initial discharge.
