The invention relates to an electrode (16) for a welding torch (17) or a cutting torch, comprising a main body (1) and a tip (3) arranged on an end surface (2) of the main body (1). The main body (1) is designed as a hollow body that is open on at least one side. On a side opposite one of the tips (3), the main body has an opening (4) for introducing a cooling medium into an interior space (7) of the main body (1), and at least two regions (5, 6) in the interior space (7), the two inner diameters of which are different from one another, and a transition region (8) located between the two regions (5, 6) having an inner diameter that decreases in the direction of the tip (3)

Resistance spot rivet welding systems, subsystems, and methods of use thereof are provided.

Resistance spot rivet welding systems, subsystems, and methods of use thereof are provided.

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.

A welding gun adapted to secure a contact tip within the welding gun without threading the contact tip and without the use of tools. The contact tip may be adapted to abut a surface of a first member disposed within the welding gun. The surface may be a surface of a gas diffuser. The surface may be adapted to abut the contact tip. The contact tip also may be adapted for abutment with a second member to urge the contact tip toward the first member. The second member may be a portion of a nozzle adapted to abut the contact tip to urge the contact tip toward the surface of the first member. A method of assembling a welding gun also is provided. The method may include disposing a contact tip between a first and a second member and capturing the contact tip between the first and second members.

Present embodiments include systems and methods for stick welding applications. In certain embodiments, simulation stick welding electrode holders may include stick electrode retraction assemblies configured to mechanically retract a simulation stick electrode toward the stick electrode retraction assembly to simulate consumption of the simulation stick electrode during a simulated stick welding process. In addition, in certain embodiments, stick welding electrode holders may include various input and output elements that enable, for example, control inputs to be input via the stick welding electrode holders, and operational statuses to be output via the stick welding electrode holders. Furthermore, in certain embodiments, a welding training system interface may be used to facilitate communication and cooperation of various stick welding electrode holders with a welding training system.

In an electrode chip attachment device, a guide member which is formed such that the guide member can be divided into a first half member and a second half member with a division surface that is passed though the communication hole and that is parallel to the axial direction and a coupling shaft serving as a separate mechanism which separates the first half member and the second half member from each other when the chip holder is pushed into the first tapered portion and the second tapered portion from the opposite side of the electrode chip and which passes the chip holder to the side of the electrode chip.

According to an embodiment of the disclosure, a welding rod holder comprises a body, an electrical contact tip, a slider, and a biasing mechanism. The body has a lower end and an upper end. The electrical contact tip is coupled to the body and is configured to electrically contact a welding rod. The slider is configured to allow the welding rod to move with respect to the body. The biasing mechanism is configured to move the welding rod out of a lower end of the body. The hand brake is configured to selectively allow the biasing mechanism to move the welding rod out of a lower end of the body. The movement of the welding rod out of a lower end of the body is configured to allow a substantially similar distance between the body and a welding work as the welding rod is exhausted.

A welding accessory that allows a welder to easily maintain the proper electrical arc gap between the welding torch and the surface being welded, and that improves the consistency of the shield gas plume by reducing the variation of gap between the shield gas nozzle and the surface being welded while in motion is disclosed. In a preferred embodiment, the welding accessory is comprised of a body portion, a slidable and rotatable repositionable arm; and a wheel attached to one end of said repositionable arm. A kit that comprises the welding accessory of the present invention and other accessories for welding and/or oxy-fuel cutting is also disclosed.
