GAS LENS ASSEMBLY

摘要

A gas lens assembly for an arc welding torch includes a lens body (24), a passage (30) through the lens body for receiving an electrode (48) therethrough and for permitting flow of an inert gas in the passage. A lens housing (32) is secured to the lens body. One or more openings in the forward end portion of the lens body enable the inert gas to flow from the passage into the housing. The gas lens assembly includes a flow control device (36) associated with the housing through which said inert gas is adapted to flow. The gas lens assembly includes a holder (34) for the flow control device releasably and removably attached to the lens housing whereby the flow control member may readily be replaced.
