摘要： A tip gas distributor is provided that preferably comprises a plurality of swirl holes and a plurality of secondary gas holes, wherein the swirl holes direct a plasma gas to generate a plasma stream, and the secondary gas holes direct a secondary gas to stabilize the plasma stream. Additionally, a tip gas distributor is provided that comprises swirl passages and secondary gas passages formed between the tip gas distributor and an adjacent component to generate and stabilize the plasma stream. Further, methods of generating and stabilizing the plasma stream are provided through the use of the swirl holes and passages, along with the secondary gas holes and passages.

摘要： A plasma arc torch has a cathode and electrode having connecting ends configured for a coaxial telescoping connection with one another on a central longitudinal axis of the torch. The connecting ends have interengageable detents thereon, with at least one of the detents being movable in a generally radial direction relative to the central longitudinal axis of the torch between an undeflected state and a deflected state. The at least one detent is movable from the undeflected state to the deflected state when the cathode and electrode are telescoped one into the other, and is movable from the deflected state back toward the undeflected state when the cathode and electrode are further telescoped tc, a point where the detents on the cathode and electrode are generally axially aligned. In this position, the at least one detent is engageable with the other detent to interconnect the cathode and electrode and inhibit axial movement of the electrode away from the cathode.
摘要翻译：等离子弧焊炬具有阴极和电极，其连接端被配置为在炬的中心纵向轴线上彼此同轴伸缩连接。连接端部具有相互接合的制动器，其中至少一个棘爪可相对于割炬的中心纵向轴线在非偏转状态和偏转状态之间沿大致径向方向移动。当阴极和电极一个伸缩到另一个时，至少一个棘爪可以从未偏转状态移动到偏转状态，并且当阴极和电极进一步伸缩时，可以从偏转状态向未偏转状态移动tc，其中阴极和电极上的棘爪通常轴向对齐。在该位置，至少一个棘爪可与另一个棘爪接合，以使阴极和电极相互连接，并阻止电极远离阴极的轴向移动。
