A shear stud welding system is disclosed. The system comprises a shear stud holder, a robotic arm and a microcontroller. The shear stud holder comprises a turret and a first motor coupled to the turret and configured to rotate the turret about an axis to a predetermined angle such that a shear stud among the plurality of shear studs is at a dispensing position. The robotic arm is configured to transfer the shear stud from the shear stud holder to a workpiece. The microcontroller is configured to control the movement of the robotic arm to pick up the shear stud from the dispensing position and transfer the shear stud holder to the workpiece at a welding position and cause the first motor to rotate the turret to a predetermined angle to cause a shear stud among the plurality of shear studs assume the dispensing position.

A welding system includes power conversion circuitry configured to convert input power to weld power and a first housing surface. The first housing surface includes a first mating geometry configured to mate with a first complementary geometry of a first modular surface of a first modular component of the welding system.

An example wire feeder includes: a wire supply support configured to supply welding wire; a wire drive assembly configured to feed wire to a welding gun from the wire supply support; a support base defining a lower surface, the wire supply support and the wire drive assembly supported by the support base, the support base being pivotable from an operational position to a travel position; a handle at a first end of the support base; and at least one reduced friction element extending from a second end of the support base so that the support base is in contact with a support surface when the support base is in the operational position, and the reduced friction element is in engagement with the support surface and the support base is out of contact with the support surface when the support base is pivoted to the travel position.

A welding cart with a cable management system may include a frame, a shelf adapted to support a welding machine, a plurality of upright members, a plurality of wheels supporting the cart, one or more pairs of holders disposed on one or more sides of the cart, and a removable bar that may be releasably secured to the one or more pairs of holders. The bar may be releasably secured to the holders via a pin-and-hole mechanism and may have a hook adapated to hold welding equipment such as cables. The bar may be releasably secured to a first pair of holders disposed on a side of the cart or a second pair of holders disposed on another side of the cart. This system provides additional, easily accessible storage space for welding tools and accessories while still being compatible with a wide variety of portable welding machines.

This disclosure relates generally to Gas Metal Arc Welding (GMAW) and, more specifically, to Metal-cored Arc Welding (MCAW) of mill scaled steel workpieces. A metal-cored welding wire, including a sheath and a core, capable of welding mill scaled workpieces without prior descaling is disclosed. The metal-cored welding wire has a sulfur source that occupies between approximately 0.04% and approximately 0.18% of the weight of the metal-cored welding wire, and has a cellulose source that occupies between approximately 0.09% and approximately 0.54% of the weight of the metal-cored welding wire.

In some aspects, autonomous motion devices configured to operably connect to a plasma torch of a plasma cutting system can include: a body to support a power supply of the plasma cutting system and move relative to a workpiece; a torch holder connected to the body and configured to position a plasma arc torch tip of the plasma torch relative to a region of the workpiece to be processed; a drive system to translate the body supporting the power supply and torch autonomously relative to a surface of the workpiece during a plasma processing operation; and a processor in communication with the drive system and configured to communicate with the power supply, the processor being configured to control the translation of the body relative to the workpiece in accordance with the plasma processing operation.

The subject innovation described herein generally pertains to a system and method for security features for a device in which functionality of the device can be limited or restricted in accordance with one or more security layers. To access functionality of the device, an appropriate security-related input is required.
