<p>The invention contemplates a host-torch body configuration for interchangeable use of a seleted one of a variety of different welding-process heads. A bayonet-type locking engagement is quickly operable to connect or disconnect any selected process head. The arrangement is such that the same bayonet-lockable engagement serves electrical-supply, consumable-electrode supply, and gas-supply or gas-venting requirements of particular different welding-process heads.</p> |
