FIELD: process engineering.
SUBSTANCE: invention relates to plasma welding. Proposed device comprises long electrode holder with front surface at electrode point and bore made thereat on mid axis through electrode holder and emission inserts fitted in said bore to make emission insert emitting surface free. Note here that emitting surface is shifted backward relative to front surface of electrode holder while plasma torch electrode includes its seat and electrode holder. Note here that said seat has internal thread while electrode holder has external thread and solid ring in at groove at outer cylindrical surface. Note also electrode holder is screwed in electrode seat by outer and inner thread and sealed by solid groove. Claimed plasma torch incorporates abode described electrode.
EFFECT: longer life.
