Abstract
A quick disconnect for use in a plasma arc torch is provided wherein a plurality of connections disposed therein are configured such that the connections break in a specific order when the quick disconnect is disengaged. Preferably, the quick disconnect comprises a plurality of signal pin connections, a pilot return connection, a fluid connection, and a main power connection. Accordingly, the signal pin connections break before the pilot return connection, the fluid connection, and the main power connection. Further, the pilot return connection breaks before the fluid connection and the main power connection, and the fluid connection breaks before the main power connection as the quick disconnect is disengaged. As a result, a safer quick disconnect in which both gas and electric power are conducted is provided by the present invention.
