Electrode diameter sensing consumables are disclosed. An example shielded metal arc welding (SMAW) torch comprises: a handle; a clamp coupled to the handle configured to open and close to hold a SMAW electrode, the clamp comprising a pivot configured to rotate based on a degree of openness of the clamp; and a potentiometer coupled to the pivot such that an output of the potentiometer is representative of a degree of rotation of the pivot

A method of operating a welding torch using a rotating coupler assembly that operates between 0 and 800 amps. The rotating coupler assembly allows for 360 degrees of rotation while keeping rotational friction at a minimum. The breakaway torque for the rotating coupler assembly is insignificant and the rotating coupler assembly can be rotated with little effort by hand. While the rotating coupler assembly minimizes rotational friction the design allow for rotating coupler assembly to continue to operate after 1-5 mm of wear on the contact surfaces. An embodiment of the rotating coupler assembly can be quickly disconnected from the unicable.

The present disclosure provides a welding system capable of detecting a size of a welding material and automatically implementing appropriate arc starting parameters. The welding system includes a welder, a welding torch, and a sensor, in which the sensor is configured to detect the size of the welding material, directly or indirectly. The welder is automatically configured to produce an arc having the arc starting parameters determined from the size of the welding material detected by the sensor. The present disclosure decreases operational error by automatically changing arc starting parameters and/or welding parameters based upon a change in welding material size, rather than requiring an operator to manually change the arc starting parameters and/or welding parameters.

Methods and apparatuses for extending the range, reach, and/or length of a welding tool. A welding extension in accordance with an aspect of the present disclosure comprises an extension bar that couples between a welding tip and a welding head, such that material passes from the welding head to the welding tip through a bore in the extension bar.

A robotic shear stud welding system includes a stud feeder, a ferrule feeder, at least one work zone, a robot, and a welding gun. The stud feeder is configured to hold a plurality of studs and feed a single stud therefrom. The ferrule feeder is configured to hold a plurality of ferrules and feed a single ferrule therefrom. The robot has a controllable arm that is configured to accurately move between the stud feeder, the ferrule feeder, and each of the at least one work zones. The welding gun is attached to the distal end of the controllable arm. The welding gun is configured to pick up the single stud from the stud feeder, pick up the single ferrule from the ferrule feeder and position the single ferrule at a bottom of the single stud, and shoot the single stud to a workpiece in one of the at least one work zones.

A welding gun is provided that includes an elongated body having a longitudinal axis, a neck assembly connectable to the elongated body, and a handle including a sleeve portion mounted around and longitudinally fixed relative to the elongated body, and a grasping portion extending lengthwise radially outwardly from the sleeve portion. The welding gun also includes a rotation mechanism including an inner structure fixedly provided along an outer periphery of the elongated body and having a number of circumferentially distributed engaging elements, and an outer structure fixedly provided along an inner periphery of the sleeve portion and having a number of circumferentially distributed engaging elements. The engaging elements of the outer structure cooperate with the engaging elements of the inner structure for releasably locking the elongated body into a plurality of discrete angular positions relative to the sleeve portion about the longitudinal axis.

Apparatuses, systems, and/or methods for providing welding systems or portions of welding systems that provide a tip-retention device that is configured to direct gas radially towards a contact tip.

An automatic welding machine includes a link actuator in which a distal end side link hub is coupled to a proximal end side link hub via three or more link mechanisms and the position of the distal end side link hub relative to the proximal end side link hub can be arbitrarily changed. The automatic welding machine is provided with one or more linear motion actuators configured to cause the proximal end side link hub of the link actuator to advance/retract relative to a mount along respective axes, and a welding torch is mounted on the distal end side link hub. The automatic welding machine further includes a movement mechanism on which peripheral devices connected to the welding torch via cables are mounted so as to be movable in one or more axial directions.

The invention relates to a holder (10) with a securing means (1) for releasably securing a hand-held torch (5), the securing means (1) having at least in regions a negative form (2) of the hand-held torch (5) for reproducibly positioning the hand-held torch (5) in the holder (10), and the securing means (1) being adapted, at least in regions, to the outer contour (3) of the hand-held torch (5) when the hand-held torch (5) is secured. The invention further relates a hand-held torch (5) having a holder (10).

A method for providing a welding score, comprising determining an initial position of a welding operation, determining a terminal position of the welding operation, determining a welding path between the initial position and the terminal position, and determining the welding score based on the welding path, wherein the welding score takes into account one or both of a time used for welding and a length of the welding path. A system comprising a welding torch, and a computer configured to: determine an initial position of a welding operation, determine a terminal position of the welding operation, determine a welding path between the initial position and the terminal position, determine a welding score, wherein the welding score takes into account a time used for welding and/or a length of the welding path, and comparing the welding score to a score threshold.
