ABSTRACT:
In accordance with one exemplary embodiment, there is provided a welding torch that includes features facilitating aligned assembly of various components of the welding torch with respect to one another. For example, the welding torch includes a nipple that carries a pin member extending from both an inner peripheral surface and an outer peripheral of a sleeve of the nipple. This pin engages with a slot on a coupling member and a slot on a neck assembly, thereby facilitating proper alignment of the neck assembly, coupling member, and nipple with respect to one another. Moreover, the engagement between the pin member and the slots block pivotal displacement of neck assembly, coupling member, and neck assembly with respect to one another. Advantageously, the use of a single pin member for both slots presents a more judicious construction, leading to reduced manufacturing costs, for instance.
