20100108654 | WELD PARAMETER INTERFACE - A system and method for determining settings or parameters for a welding-type power source are provided. By presenting an operator with an interface that is positioned along the path of a weld cable and configured to input weld characteristics, an operator is not required to determine electrical parameters for setting a welding-type power source output at the power source. The interface is presented to the operator at a remote welding-type device, such as a wire feeder, a weld robot, a torch, or the like. From the operator-specified weld characteristics, the system and method determine appropriate settings for the power source. In some embodiments, the system and method may automatically set the power source accordingly. | 05-06-2010 |
20110114612 | Method and Apparatus For Welding - A method and apparatus for welding include initiating a pulse welding process includes initiating a welding arc by providing CC type welding power, maintaining the arc by providing CV type power. Then, pulse type welding power is provided. The method and system can be used to start short circuit, or other welding processes by providing short circuit power, or welding power of a given mode, instead of providing pulse power. Also, in one alternative, a method and system of initiating a pulse, short circuit, or given welding process includes initiating a welding arc by providing CC type welding power at least until a pseudo-equilibrium for the arc is established. Then, providing welding power in a pulse, short circuit, or the given mode. | 05-19-2011 |
20120085741 | Method and Apparatus for Monitoring Weld Cell - A method and apparatus for monitoring weld cell and related activity is disclosed. The activity is sensed using a variety of sensors, and reported to the controller, or to a remote location. | 04-12-2012 |
20130264319 | Weld Cell System With Communication - A method and apparatus for providing welding-type power is disclosed and includes a means for communicating. | 10-10-2013 |
20130270245 | Method and Apparatus For Welding - A method and apparatus for welding include initiating a pulse welding process includes initiating a welding arc by providing CC type welding power, maintaining the arc by providing CV type power. Then, pulse type welding power is provided. The method and system can be used to start short circuit, or other welding processes by providing short circuit power, or welding power of a given mode, instead of providing pulse power. Also, in one alternative, a method and system of initiating a pulse, short circuit, or given welding process includes initiating a welding arc by providing CC type welding power at least until a pseudo-equilibrium for the arc is established. Then, providing welding power in a pulse, short circuit, or the given mode. | 10-17-2013 |
20140069901 | Method and Apparatus For Welding With CV Control - A method and apparatus for welding is disclosed. The output is preferably a cyclical CV MIG output, and each cycle is divided into segments. An output parameter is sampled a plurality of times within one or more of the segments. The CV output is controlled within the at least one segment in response to the sampling. The parameter is output power, a resistance of the load, an output current, an output voltage, or functions thereof in various embodiments. The control loop is preferably a PI or PID loop. The loop may be applied only within a window. The set point may be taught or fixed. The system can be used to weld with a controlled arc length. | 03-13-2014 |
20140190959 | Method and Apparatus For Pulse and Short Circuit Arc Welding - A method and apparatus for multi process welding includes providing a controlled short circuit output and a pulse output in response to a user selection across a workpiece output stud and a torch output stud. | 07-10-2014 |
20140203007 | COOPERATIVE WELDING SYSTEM - The present invention includes a welding system that has at least two metal inert gas (MIG) welders configured to perform a cooperative pulsed MIG welding process. The welding system also includes at least one communications link connecting the at least two MIG welders to deliver at least one of subordination commands and superiority commands to either of the at least two MIG welders to synchronize the cooperative pulsed MIG welding process. | 07-24-2014 |
