TIG WELDING SYSTEM AND METHOD

摘要

The invention provides a welding arrangement designed to respond the need of an improved welding system that aids in supplying filler material (62) to a weld location. Provided is a welding system including a welding gun (18) and a welding wire feed (94) directly coupled to the welding gun. The welding gun includes a filler material housing (96), a filler material positioning extension (84), and a manual advancement device (97) configured to advance a filler material through the welding wire feed. Further provided is a method of operating a welding gun. The method includes passing a current between an electrode (44) and a work piece at a weld location, and advancing a filler material toward the weld location via a channel of a positioning extension in response to engagement of a manual advancement device.
