A welding shield that is configured to provide improved gas distribution adjacent a weld seam during the welding process so as to improve the weld quality. The welding shield includes a central member wherein the central member includes contiguously formed sidewalls and a top wall operable to create an interior volume. Mounted within the interior volume is a gas distribution module that is operably coupled to a gas source. A clip member is mounted to the central member and is configured to provide retention of the gas distribution module. A torch retention member is movably mounted to the top wall of the central member. The torch retention member is configured to receive and secure a welding torch and further provide rotational and pivotal movement thereof. A plasma cutter holding member is further included and is operable to releasably retain a plasma cutter.

Provided herein is a quick disconnect torch handle for use in a plasma arc system. In one approach, the plasma arc system includes a lead having a first end connected to a power source and a second end connected to a torch handle. The quick disconnect is located at a proximal end of the torch handle, and may include at least one signal connection, a pilot connection, a fluid connection, and a main power connection. The fluid and power connection may be formed by a connection between a main power socket and a conductive conduit. Specifically, the main power socket includes a conductive spring and an O-ring encircling an interior bore thereof. Removal of the conductive conduit from the main power socket causes the fluid connection to break between the O-ring and the conductive conduit, and then the power connection to break between the conductive spring and the conductive conduit.

Apparatus for allowing a welder to control the output power of a welding machine, and thus its arc power by applying force to a surface of a force sensing transducer assembly. The force sensing transducer assembly generates a force signal based upon the force applied, for example by reducing the resistance within the force sensing transducer assembly. A control interface module then receives the force signal and controls the welding machine power output based upon the force signal. The welder may set the range of force to change the arc power by setting a minimum amount of force to actuate the welding machine and a maximum force that increases the output power of the welding machine (force below the minimum does not actuate the welding machine and force above the maximum does not increase the welding machine power above a certain level).

A locator-equipped clamp jig capable of suppressing interference between base sections of segments when clamped by the clamp jig, a stator manufacturing device, and a method for manufacturing a stator. The locator-equipped clamp jig has a locator that is provided to part of a main clamp body on a stator core side and has a plurality of protrusions arranged on an upper surface of an electrical conductor that is adjacent, in the radial direction of the stator core, to an electrical conductor being clamped by the main clamp body, the width of the protrusions in the radial direction of the stator core being at least the width of one of the electrical conductors.

The invention relates a torch body for thermal joining of at least one workpiece, in particular for arc welding or arc brazing, said torch body comprising a non-consumable electrode provided in the body, in particular a tungsten electrode, for generating an arc between the electrode and the workpiece. The torch body has an end nozzle, which is devoid of potential, for discharging a shielding gas flow from a gas outlet. A secondary flow channel is provided for dividing the shielding gas flow into a main gas flow and a secondary gas flow, the secondary gas flow annularly surrounding the main gas flow at the gas outlet.

A welding torch for arc welding, comprising a holder for retaining a welding electrode and for transmitting electric current to the welding electrode, a neck attached to the holder for supporting the holder and for transmitting electric current to the holder and a handle attached to the neck at a distal end of the handle. The neck is arranged to be connected to a cable for transmitting electric current to the neck, the handle is arranged to be attached to the neck at a distal end of the handle, the handle is arranged to receive the cable inside the handle. The handle comprises a body made of flexible material, for allowing movement of the distal end of the handle in relation to a proximal end of the handle.

Disclosed is an apparatus for arc welding, comprising: a torch body comprising a power supply line and a gas supply line; two or more metal segments movable relative to one another being sized and shaped to surround a seam between two elongated objects to be welded together, the two or more metal segments being in electrical communication with the power supply line; and a gas jacket attached to each of the metal segments.

An inductive sensor which includes one or more inductive coils and an inductance to digital converter. The output of the inductive sensor may be used to replace the functions of a switch and a potentiometer to initiate and control various outputs in welding-type systems and applications.

A rotatable and removable connection for use in a welding torch assembly that allows for the gooseneck to be removeable and rotatable by the use of an interference member that allows the welding torch assembly to enter a locked, unlocked and partially lock state by moving the interface member about the central axis of the welding torch assembly, the partially lock state allows for rotation of the gooseneck without allowing for removal of the gooseneck, and the electrical connection provides electrical conduction via a conduction member that is independent form the locking features of the welding torch assembly.

A welding tool comprises a main body; a handle attached to the main body to be held by a welder; an electrode attached to the main body; an adjusting device for moving the consumable electrode forward/backward with respect to the main body; a control unit is connected to the adjusting device and is configured to act on the adjusting device for maintaining a substantially constant distance between the electrode and a weld area.
