  • Method for noise reduction
    Patent number: 5138132
    Abstract: This invention relates to a method for noise reduction and stabilization of the welding arc in TIG-ac-welding machines with self-commutated inverter current sources where the alternating frequency of the welding current is preferably changed in the inverse direction as a function of the amount of the welding current.

  • Method for reducing the generation of noise during arc welding
    Patent number: 5101092
    Abstract: A method for reducing the generation of noise during arc welding by alternating current with welding machines with clocked current sources is disclosed. By modifying the curent set value on the control side with temporally non-linear functions by a digital-analog converter, a flow of the welding current which has limited upper tones can be generated.
