The specification discloses a Basic Surge Protector for protecting an electrical equipment connected on its load side from spurious or excessive transient voltages or surges or both on an electrical line above a predetermined value, on its line side or its hot side. Intended for use in ac circuits, dc circuits and ac / dc circuits. A fuse is used to monitor a fault current flowing into a surge voltage suppression device, due to an excessive voltage across the suppression device. Thus the fuse blows resulting from an over-current condition, and it disables and opens a solid state switch or an electro mechanical switch mounted in series in the line thus protecting the secondary or the load side from over-voltages and transient surges on the electrical line. Circuits are also disclosed which provide for automatic setting and resetting after an over-voltage fault condition on the line being protected. The lightning and surge protection as provided by this invention may also be rendered into a single chip solid state device.

A plasma arc torch has a threadless electrode-cathode locking assembly, a one-piece tip assembly, and a rotational contact starting mechanism. The cathode and electrode of the locking assembly are configured such that relative rotation of the electrode with respect to the cathode causes the electrode to move in an axial direction relative to the cathode for locking the electrode in fixed axial and rotational position with respect to the cathode. The inner wall of the one-piece tip assembly is configured to receive the forward end of the electrode in a non-contact position. Rotation of the electrode with respect to the tip causes an arcing formation on the electrode to contact an arcing chamber within the cavity. Rotation of the electrode away from the tip generatesa pilot arc in the arcing chamber.

In some embodiments, the present invention provides an independently tightening collet surrounding each socket for each of a plurality of corresponding high-electrical-power prongs, wherein the collet is loosened for normal (low-insertion-force) insertion and withdrawal of the plug from the outlet. Once the plug is inserted, the collet is tightened, providing a high-contact force to lower the contact resistance and to help keep the plug from coming unplugged. In some embodiments, the plug is not “locked”, in that a tension force pulling on the plug will overcome the contact force at a point before the plug or outlet is damaged, and the plug is allowed to come unplugged. In some embodiments, engaging the collet will also provide a wiping or sliding motion between the prong and socket for each connection, thus wiping at least some dirt or corrosion away and providing a lower-resistance better electrical contact.
