Abstract: A welding gun includes a control switch combined with a trigger. The control switch features a slide movable to at least first and second positions. In an operating mode, the control switch switches between two differing sets of welding parameters in the first and second positions. In another operating mode, the control switch operates a safety lock-out, allowing activation of the welding gun by the trigger in one position and preventing activation in the other position. For operator convenience, the control switch may be positioned to slide transversely relative to the wire passageway of the weld gun with which the trigger is generally aligned.

Abstract: A welding gun includes a handle, an input line, a neck and an acoustic wave trigger. The handle is configured to be grasped by an operator and includes first and second ends. The input line connects to a first end of the handle and is configured to deliver wire and/or gas to the welding gun. The neck is operatively connected to the second end of the handle. The wire and/or gas passes into the neck and out through a nozzle. The acoustic wave trigger is secured to the handle and activates the welding gun when merely touched, as opposed to being squeezed or pressed, by the operator.
