Abstract

A welding gun is provided that includes an elongated body having a longitudinal axis, a neck assembly connectable to the elongated body, and a handle including a sleeve portion mounted around and longitudinally fixed relative to the elongated body, and a grasping portion extending lengthwise radially outwardly from the sleeve portion. The welding gun also includes a rotation mechanism including an inner structure fixedly provided along an outer periphery of the elongated body and having a number of circumferentially distributed engaging elements, and an outer structure fixedly provided along an inner periphery of the sleeve portion and having a number of circumferentially distributed engaging elements. The engaging elements of the outer structure cooperate with the engaging elements of the inner structure for releasably locking the elongated body into a plurality of discrete angular positions relative to the sleeve portion about the longitudinal axis.

Dependent claims

A welding gun comprising:

an elongated body having a front end, a rear end, and a longitudinal axis extending between the front end and the rear end;
a neck assembly having an end connectable to the front end of the elongated body;
a handle including a sleeve portion mounted coaxially around and in a fixed longitudinal relationship with the elongated body, and a grasping portion extending lengthwise radially outwardly from the sleeve portion;
and
a rotation mechanism operatively connected between an outer periphery of the elongated body and an inner periphery of the sleeve portion for rotating the elongated body and the neck assembly relative to the handle about the longitudinal axis, the rotation mechanism including:
an inner structure fixedly provided along the outer periphery of the elongated body, the inner structure having a number of circumferentially distributed engaging elements;
and
an outer structure fixedly provided along the inner periphery of the sleeve portion, the outer structure having a number of circumferentially distributed engaging elements, the engaging elements of the outer structure cooperating with the engaging elements of the inner structure for releasably locking the elongated body into a plurality of discrete angular positions relative to the sleeve portion about the longitudinal axis.
