Embodiment Construction

[0019] see figure 1 , which shows a typical metal inert gas (MIG) welding system 20 . However, the invention is also applicable to other electrode-fed welding systems, such as submerged arc welding. The illustrated MIG welding system 20 includes a power supply / wire feeder 22 , a gas cylinder 24 containing gas 25 , a drum 26 of an electrode electrode 27 , a welding torch 28 , a welding cable 30 , a work clamp 34 and a grounding cable 32 . In the illustrated embodiment, gas 25 and electrode 27 are delivered from power source / wire feeder 22 to welding cable 30 . The welding cable 30 then delivers the gas 25 and the electrode 27 to the welding torch 28 . The power supply / wire feeder 22 may also consist of an independent power supply and an independent wire feeder.

[0020] The welding cable 30 also has wires (not shown) that carry the high current from the power source / wire feeder 22 to the welding torch 28 . The power supply / wire feeder 22 is operable to control the feeding o...

Abstract

A welding gun having a removable end portion. The end portion may be adapted to direct gas from the welding gun. The end portion may be conical-shaped. The end portion may be removed without tools. The end portion also may be adapted to be secured to and / or removed from the welding gun in a linear movement. A method of assembling a welding gun. The method may comprise urging a nozzle end member and a nozzle body into engagement to secure the nozzle end member to the nozzle body.

Description

technical field [0001] The present invention relates generally to welding systems, and more particularly to a welding gun having a nozzle adapted to direct a flow of gas from the welding gun. Background technique [0002] Welding is the method of joining or dividing metal objects. Arc welding is a common type of welding. Arc welding systems generally include a power source connected by cables to a welding torch equipped with electrodes. Ground cables are used to connect metal objects to a power source. When the electrode is placed against the metal object, the electrode inside the welding handle forms an electrical circuit between the power source and the metal object, allowing current to flow through the electrode and the metal object. The current creates an arc between the electrodes and the metal object. The heat of the arc melts metal objects near the arc. Filler materials may be added to the molten metal. For example, an electrode may be placed against a molten po...
