摘要： An example conversion apparatus for a welding torch (14) includes: an insulator configured to be mechanically coupled to a first component of a welding torch, to insulate the first component from a first contact tip (20), and to guide shielding gas through a bore of the insulator, wherein the first component is configured to be in electrical contact with a second contact tip (18); and a contact tip holder configured to be attached to the welding torch via the insulator, to hold the first contact tip, to conduct welding current to the first contact tip, and to receive the shielding gas from the insulator.

摘要： Described herein are examples of weld training systems that show (e.g., transparent and/or translucent) "ghost" images of a welding tool on a display screen of a welding headgear to indicate target positions and/or target orientations of an actual welding tool. In some examples, the weld training systems may additionally "reset" the target tool image to a position closer to the actual welding tool if the target tool image gets too far away. The ability to "reset" the target tool image to a position closer to the actual welding tool may help in minimizing a risk that an operator 106 will overcompensate to try to catch up with the target tool image, which can be detrimental to the weld. Additionally, resetting the target tool image to a position closer the welding tool may allow an operator to better perceive and/or understand differences in orientation and/or other technique parameters.

摘要： An example audio device includes: communication circuitry configured to receive a first signal representative of an audible sound associated with a welding-type waveform; audio processing circuitry configured to generate, based on the first signal, a welding noise cancellation signal to produce destructive interference to the audible sound; and a transducer configured to output the destructive interference using the welding noise cancellation signal.

摘要： The present disclosure is directed to systems and methods for pretreating a wire that is used in a welding operation. Using embodiments of the systems and methods disclosed herein, one may remove hydrogen and/or other contaminants from a wire by passing the wire through a pre-treatment chamber, preferably one that isolates the gas discharged from the pre-treatment chamber from the shielding gas utilized in the welding operation; treating the wire within the pre-treatment chamber to release hydrogen and/or other contaminants; and creating a turbulent flow of gas through the pre-treatment chamber. By creating a turbulent flow of gas within the pre-treatment chamber, the transportation of the released hydrogen and/or other contaminants away from the wire may be improved, thereby preventing released contaminants from being reintroduced to the wire or otherwise transported into a weld.

摘要： Disclosed example travel speed pacing systems for welding-type operations include: an interface configured to receive a first input describing a characteristic of a welding-type operation, and configured to receive an operation length of the welding-type operation; and control circuitry configured to: determine a target travel speed based on the first input; determine a target operation time based on the target travel speed and the operation length; and provide a time output representative of least one of a duration of the welding-type operation or a remaining amount of the target operation time.

摘要： The present application relates to a welding-type power supply (102) for synergically controling a welding-type output during a welding-type operation. An example welding-type power supply (102) includes a power conversion circuit (110) configured to convert input power to welding-type power and to output the welding-type power to a welding-type torch (106); a communication circuit (118) configured to receive a control signal from a remote control device during a welding-type operation; and a control circuit (112) configured to synergically control at least two of a voltage of the welding-type power output by the power conversion circuitry (110), a current of the welding-type power, or a wire feed speed.
