Abstract: A method for controlling a start of a metalworking operation. The method includes detecting an initial contact between a wire being fed from a welding apparatus and a workpiece and, in response to the detection, halting feeding of the wire from the welding apparatus. The method further includes activating a high energy heat source configured to heat a tip of the wire and resuming the feeding of the wire from the welding apparatus when the tip of the wire is heated by the high energy heat source to a plastic state. The feeding of the wire is resumed by measuring a force feedback from the wire contacting the workpiece. An apparatus for implementing the method is also disclosed.

Abstract: An example contact tip for a welding torch includes: a first body section having a first diameter and exterior threads, the first body section having channels extending longitudinally along an exterior surface of the first body section to permit gas flow from a first end of the contact tip to a second end of the contact tip through the channels; a first bore portion having a first inner diameter; and a second bore portion having a second inner diameter configured to contact an electrode wire traveling through the second bore portion, the first inner diameter being larger than the second inner diameter.
