  • Electronic welding energy source
    Patent number: 4525621
    Abstract: An electronic welding energy source comprises interconnected control and power circuits together with independently operable circuits for setting the static and dynamic characteristics respectively of the source.
    Type: Grant
    Filed: January 3, 1983
    Date of Patent: June 25, 1985
    Inventor: Peter Puschner
  • Method and apparatus for arc welding
    Patent number: 4249061
    Abstract: A process for adjusting a welding torch with respect to a weld joint formed between two workpieces is disclosed, including determining operating quantities for arcs located in at least two positions relative to said weld joint, deriving characteristic values for each of those operating quantities, mathematically combining such characteristic values, and comparing the mathematical combination with a theoretically calculated value for such characteristic values, and then adjusting the position of the welding torch in accordance with the difference between the mathematical combination of those characteristic values and their theoretically calculated value.
    Type: Grant
    Filed: August 21, 1978
    Date of Patent: February 3, 1981
    Inventor: Peter Puschner
  • Method and apparatus for arc welding
    Patent number: 4201906
    Abstract: A method of and apparatus for arc welding, in which an energy source supplies the welding process and a simulated process in a bridge circuit the output of which, via an amplifier and a discriminator circuit controls the operation of the source in one of two or more modes having different characteristics such as constant voltage or constant power.
    Type: Grant
    Filed: June 23, 1978
    Date of Patent: May 6, 1980
    Inventor: Peter Puschner
  • Apparatus for obtaining feedback signals for controlling a parameter of an arc welding machine
    Patent number: 4169224
    Abstract: Apparatus is provided for controlling a parameter of an arc welding machine, such as the height and/or the lateral position of the welding tool. The apparatus includes a parallel circuit having first and second branches connected to a source of voltage, wherein the first branch includes the arc welding machine to be controlled, and wherein the second branch includes an electrical analog of the current-voltage characteristics of the welding machine when operating as desired. A differential amplifier is provided for comparing the current in the first and second branches and providing a parameter-indicative signal representing the current difference between the first and second branches. In addition, a control circuit is responsive to the parameter-indicative signal and is provided for adjusting various parameters of the welding machine, including the height of the welding tool and/or the lateral position of the welding tool.
