Patent number: 8552339Abstract: A system and method for powering a welding-type device from a plurality of distinct outlet configurations is disclosed. The power cord system includes a power cord having a plurality of conductors extending therethrough. An end of the power cord is constructed to engage an individual adapter of a plurality of adapters. Each of the plurality of adapters has a prong configuration that is different than a prong configuration of the other adapters such that each of the plurality of adapters is constructed to electrically connect the power cord to a uniquely configured outlet. A welding-type device according to the present invention is quickly and efficiently adaptable to operate at a plurality of different input power signals.Type: GrantFiled: July 31, 2008Date of Patent: October 8, 2013Assignee: Illinois Tool Works Inc.Inventors: Thomas G. Yunk, Albert M. Nowak

Publication number: 20040164064Abstract: A welding machine with a wire feeder and a controller is disclosed. The wire feeder includes a wire feed motor with a motor speed input. The controller is coupled to the motor speed control input. A user selectable wire feed speed input is also connected to the controller. The controller has an input circuit coupled with a non-linear stage such that the relationship between the user selectable wire feed speed input and the actual wire feed speed is not linear. The selectable input may be a potentiometer mounted on a front panel as the user selectable wire feed speed input. The non-linearity may be continuous or two discrete gains.Type: ApplicationFiled: February 27, 2004Publication date: August 26, 2004Applicant: Illinois Tool Works Inc.Inventors: Albert M. Nowak, Thomas G. Yunk, Warren E. Herwig

Patent number: 6204476Abstract: An arc welding machine is disclosed for providing a continuous feed electrode to a weld site. The arc welding machine includes a line frequency transformer having a primary winding, a first secondary winding, and a second secondary winding (e.g., an extension winding, a separate winding, etc.). The first secondary winding provides a welding power having a first voltage at a welding power output terminal. The second secondary winding provides a second welding power having a second higher voltage at an input terminal of a switch, the switch being controlled to provide a pulsed power at the welding power output terminal. According to one feature, the arc welding machine produces a pulsed power having a fixed pulse width and a fixed frequency, the fixed pulse width and fixed frequency being substantially free of operator adjustment.Type: GrantFiled: May 12, 1999Date of Patent: March 20, 2001Assignee: Illinois Tool WorksInventors: Jon O. Reynolds, Todd E. Holverson, Albert M. Nowak
