The channel is capable of slideably receiving an electrode body along the longitudinal axis. The component includes a contact element disposed in the hollow body and includes a first surface and a second surface. The first surface is adapted to facilitate electrical communication with a power supply and the second surface is adapted to physically contact a surface of the electrode body when the plasma arc torch is operated in a transferred arc mode. In addition, the second surface is characterized by the absence of physical contact with the surface of the electrode body when the torch is operated in a pilot arc mode.

摘要： A locking arrangement configured to secure portable equipment includes a tubular lock having a pair of locking arms projecting from a face of the lock body. Each locking arm has a shank portion and a wing portion, the wing portion extending from the end of the shank at a right angle thereto. Each wing has a substantially flat surface. The locking arms are disposed adjacent to one another, and in the unlocked configuration, the wings of both arms are in parallel opposition such that their flat surfaces substantially meet. In the locked configuration, the wings are parallel to each other but extend in opposite directions outside the envelope. This opposite orientation of the wing members prevents the lock from being withdrawn through the locking port. Moreover, if the two shanks are seated within a port whose dimensions closely match those defined by the shanks themselves, rotation of the lock will be substantially prevented.
摘要翻译：构造成用于固定便携式设备的锁定装置包括具有从锁体的表面突出的一对锁定臂的管状锁。每个锁定臂具有柄部和翼部，翼部从柄的端部以直角延伸。每个翼具有基本平坦的表面。锁定臂彼此相邻地设置，并且在解锁构造中，两个臂的翼平行地相对地平放，使得它们的平坦表面基本上相交。在锁定构型中，翼彼此平行，但是在外壳外部以相反的方向延伸。机翼构件的这种相反方向防止锁通过锁定端口被拉出。此外，如果两个柄位于其尺寸与柄本身限定的尺寸紧密匹配的端口内，则基本上可以防止锁的旋转。

摘要： A consumable set is provided that is usable in a plasma arc torch to direct a plasma arc to a processing surface of a workpiece. The consumable set includes a nozzle having: 1) a nozzle body defining a longitudinal axis extending therethrough, and 2) a nozzle exit orifice, disposed in the nozzle body, for constricting the plasma arc. The nozzle exit orifice defines an exit orifice axis oriented at a non-zero angle relative to the longitudinal axis. The consumable set can also include an alignment surface generally parallel to the exit orifice axis. The alignment surface is dimensioned to align the exit orifice such that the plasma arc impinges orthogonally on the processing surface.
