Arc welding torch

摘要

An improved arc welding torch is provided wherein the welding torch comprises in combination a body portion having at one end an inlet for the introduction of inert gas; a head portion attached to the body portion at the end remote from the inlet for the introduction of inert gas and having at the opposite end an outlet for the discharge of inert gas, the head portion being in electrical contact with the body portion; a first conduit through the body portion for passage of the inert gas therethrough and a second conduit in the head portion for the passage of inert gas therethrough, the first and second conduits being in fluid communication; means for passing electric current through the body portion and head portion; and electrode means in electrical contact with the head portion, the improvement wherein the body portion includes a plurality of co-axial ball and socket joints and means associated with the same to maintain the ball and socket joints in any configuration to which the plurality of co-axial ball and socket joints are deformed. This allows the arc welding torch, and the electrode in particular to have access to portions of the workpiece which would be normally inaccessible.
