Patent number: 9073139Abstract: A welding torch is provided that includes a motorized arrangement for advancing continuous electrode wires during welding. The torch has a pair of rollers that contact the electrode wire to force it through the torch during welding. A force adjustment selector is provided in the torch handle that allows the operator to alter the force or pressure applied to the electrode wire. Markings on the handle, or stops provided between the selector and the handle allow for easy adjustment and verification of the proper pressure or force applied for specific types of electrode wires.Type: GrantFiled: August 10, 2006Date of Patent: July 7, 2015Assignee: ILLINOIS TOOL WORKS INC.Inventors: Mark Richard Christopher, Gerald Peter Piechowski

Patent number: 9050438Abstract: One preferred embodiment includes a guidewire manipulation device for manipulating a guidewire during a procedure. Preferably, the guidewire manipulation device includes a powered motor that drives a tandem roller assembly. The guidewire is passed through a hole positioned lengthwise through the device where the roller assembly engages the guidewire's outer surface. The interface of the manipulation device includes a power button that directs the internal roller assembly to roll the guidewire in a desired rotational direction. Additional interface controls are also preferable to provide a different roll patterns, depending upon surgeon preference and guidewire placement efficiency.Type: GrantFiled: October 18, 2007Date of Patent: June 9, 2015Assignee: VESATEK, LLCInventors: Aaron Rollins, Tor Alden

Patent number: 8450646Abstract: A retaining head for a MIG welding device includes a contact tip mounting end, an opposite retaining head mounting end, and a throughbore extending from one of the ends to the other end. A deflector is disposed along the throughbore and is adjustable for imparting a bend in welding wire passing through the throughbore. The deflector provides a straight wire contour for the welding wire that is fed out of the welding torch, while maintaining sufficient contact force between the welding wire and the contact tip. The deflector also reduces the effect of wire twist on the contact point between the welding wire and the contact tip.Type: GrantFiled: May 22, 2008Date of Patent: May 28, 2013Assignee: Illinois Tool Works Inc.Inventors: Tiejun Ma, Paul-David Pinsonneault, Thomas Jaeger

Patent number: 8357876Abstract: A method of arc welding a first metal piece to a second metal piece includes the steps of extend a welding head between the space between first and second metal pieces, bending a filler wire, passing the bent filler wire through the welding head such that an end of the bent filler wire extends in a direction toward a surface of one of the first and second metal pieces, and arc welding the end portion of the bent filler wire onto the surface of the metal piece. The method further includes rotating the end of the bent filler wire toward another surface of the metal pieces and arc welding the of end of the rotated bent filler wire onto the surface of the another metal piece. The welding head travels along the space between the first and second metal pieces as the step of arc welding occurs.Type: GrantFiled: February 25, 2010Date of Patent: January 22, 2013Assignee: ARC Specialties, Inc.Inventors: Daniel Allford, Randy Ellington, Jordan Smith

Patent number: 6708864Abstract: A weld wire for storage on a spool of weld wire. The weld wire has a substantially linear cast in the form of an undulating curve that generally lies in a single plane. The undulating curve is a succession of generally semi-circular sections having a generally fixed radius of curvature. The linear cast is formed on the weld wire prior to the weld wire being wound on the spool of weld wire. The linear cast is at least partially retained on the weld wire after the weld wire is unwound from the spool and during the feeding of the weld wire through a welding machine.Type: GrantFiled: March 26, 2002Date of Patent: March 23, 2004Assignee: Lincoln Global, Inc.Inventors: Otto Ferguson, III, Dennis K. Hartman

Patent number: 6667460Abstract: An inner torch for the electric-arc spraying of cavities, in particular of cylinder contact surfaces. The inner torch as at least two torch tubes for heating electrodes. The electrodes are provided for melting purposes and are designed as wires which can be burned away in an electric arc. The inner torch also has a gas feed for a process gas which is provided for transporting and spraying the molten wire material in the direction of the cavity surface which is to be coated. The wires are guided towards one another, by way of the torch tubes, wherein at the outlet and in the region of the electric arc, the electric arc of the electrodes wires, which is arranged in the contact region of the wires, is arranged in the region of the flow of the discharged process has, referred as the main gas arranged transversely to the main transporting direction of the wires. Furthermore, in addition to being bent towards one another, the wires are also bent transversely to this direction.Type: GrantFiled: March 11, 2002Date of Patent: December 23, 2003Assignee: DaimlerChrysler AGInventors: Detlef Nowotni, Christian Wanke, Tilman Haug, Patrick Izquierdo

Publication number: 20010045420Abstract: A welding system and method of use which allows a single welding operator to perform quick, easy and high quality vertical welds. The welding system comprises a welding fixture with a pair opposing, positionally adjustable welding shoes, and lock screws for attaching to a workpiece such as an I-beam. The welding fixture is located adjacent the end of an articulating boom, and a welding torch and oscillator are included on the welding fixture. A rotary straight wire feeder removes the cant and helix from welding wire as it is fed to the welding torch. The welding torch prevents welding wire from fusing to a guide tube in a manner which would interrupt a welding operation. The invention includes a distributed welding control system comprising a plurality of controller modules interfaced with a common bus. The control system allows a welding operator to program automated welding cycles for various welding operations.Type: ApplicationFiled: May 4, 2001Publication date: November 29, 2001Inventors: William L.
