Disclosed are wire clamps and wire bonding apparatuses including the same. The wire clamp comprises a clamping lever, a driving lever parallel to the clamping lever and having an upper support, a shaft that penetrates a center of the driving lever to connect to the clamping lever, a spring in the driving lever and on an outer circumferential surface of the shaft, and an upper pivot that protrudes from an inner wall of the upper support to separate the upper support from the clamping lever. The driving lever has a load point and an effort point on opposite sides of the shaft. The effort point is connected in a direction of a straight line to the shaft and the effort point.

A consumable assembly for use in an arc welding apparatus is provided that includes a nozzle assembly having a nozzle body, an insulator disposed within the nozzle body, and a nozzle insert disposed within the insulator. The nozzle insert includes an internal gas diverter. A contact tip is disposed within the nozzle assembly and includes at least one aperture extending from an exterior portion to an internal cavity, an exit orifice, a distal end face, and an exterior surface extending between the at least one aperture and the distal end portion of the contact tip. The internal gas diverter directs a flow of shield gas exiting the at least one aperture along the exterior surface of the contact tip, and a principal distance from the at least one aperture to the distal end face is varied to adjust the flow of the shield gas for improved cooling.

A welding gun for welding a welding stud to a substrate in a welding direction is provided, comprising a holding device for holding the welding stud during a welding operation, wherein the welding stud has a contact surface which is intended to contact the substrate before and/or during the welding operation, further comprising a stud lifting device for conveying the holding device against the welding direction to an immersing start position, further comprising a stud immersing device for conveying the holding device from the immersing start position in the welding direction, further comprising a bearing element having a bearing surface for supporting the welding gun on the substrate, and further comprising a device for automatically adapting the immersing start position relative to the bearing surface in the welding direction.

The invention uses the principle of the pneumatic turbine and a cooling system for the entire welding torch, wherein the gas used in the welding process, or even compressed air, enters through a conductor in the axial direction to the consumable, thus moving, a turbine, which in turn moves a tip and a tip holder. The welding torch can be used for extended periods of time at 100% cycle on welding machines of NEMA class I, since it is water cooled. In addition, the torch can be used in any welding source from any manufacturer, whether the machine is new or very old, as the euro standard (socket) is the same. This implies that there is no need to purchase a new welding machine, but only a torch. In construction and assembly environments, such as riser welding, refineries, joint welding, coating, and processes that aim to build a part using only one welding consumable, the use of said torch would bring a significant balance in terms of reduction of time and cost. This torch can also be used in any existing welding device, within the abovementioned processes.

A reciprocating welding device using a microcontroller to control a stepper motor to control a welding head for the stationary welding of a workpiece, the microcontroller allowing for adjustment of the welding head reciprocating stroke speed, the width of each stroke, and a pause from 0-1 second at the sides to control the wash of the welding edges, having a manipulator, the welding head and the oscillator contained in a single unit and provided on a multiple adjustment portable stand.

Cutting or welding torch component comprising a ridge (8) forming a thread for connecting the component to other parts of the cutting or welding torch, the thread having a pressure flank (81, 91), a clearance flank (82, 92), a root flat (84, 94) and a crest flat (83, 93), wherein—the angle included by the pressure flank (81, 91) and clearance flank (82, 92) is 60° or less, —the angle α included by the pressure flank (81, 91) and a plane perpendicular to the longitudinal axis (10, 20, 30) of the thread is 40° to 50°, —the angle β included by the clearance flank (82, 92) and a plane perpendicular to the longitudinal axis (10, 20, 30) of the thread is 0° to 20°, and—the height (VZ) of the ridge (8) is 0.4 times the pitch of the thread or less.

An orientation and guide mechanism for a welding system includes a pair of opposed guide members. A weld wire having a non-round cross-section is fed through a guide passageway formed between the guide members, each of which have recessed channels that combine to define the guide passageway. The guide passageway has a non-round shape corresponding to the non-round shape of the wire. The orientation mechanism and the guide members thereof is adjustable relative to a welding device of the weld system, such that the orientation of the wire can be controlled and maintained by adjusting the orientation mechanism. The wide side of the wire may be adjusted to be presented to a radiant energy source, and/or the non-round wire may be adjusted relative to the desired weld seam.
