ABSTRACT:
An improved MIG welding pliers is disclosed, which allows faster and easier removal of spatter form a MIG welding nozzle, thereby improving welder productivity. Embodiments of the present invention provide a rounded file on the outer surface of each of the pinchers of the pliers. In one embodiment, each pincher has a different file surface. The rounded file surface provides for improved spatter removal, and eliminates the need for waxes and spatter control products which degrade the contact tip and nozzle, hastening the need for their replacement. Therefore, embodiments of the present invention increase the efficiency of a MIG welding operation, as less time is spent removing spatter from nozzles, and thus, more time is available for welding. Furthermore, by avoiding the use of waxes, costs are reduced since nozzles and contact tips do not need to be replaced as frequently.
