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.
