Abstract: Provided herein is a quick disconnect torch handle for use in a plasma arc system. In one approach, the plasma arc system includes a lead having a first end connected to a power source and a second end connected to a torch handle. The quick disconnect is located at a proximal end of the torch handle, and may include at least one signal connection, a pilot connection, a fluid connection, and a main power connection. The fluid and power connection may be formed by a connection between a main power socket and a conductive conduit. Specifically, the main power socket includes a conductive spring and an O-ring encircling an interior bore thereof. Removal of the conductive conduit from the main power socket causes the fluid connection to break between the O-ring and the conductive conduit, and then the power connection to break between the conductive spring and the conductive conduit.
