  • MIG welding machine having 115V inverter
    Patent number: 7049545
    Abstract: The present invention is directed to a MIG welding machine having a 115 volt inverter. Incorporation of the 115 volt inverter into the MIG welding power source reduces the weight of the power source thereby increasing its portability. The power source may include a power factor correction circuit to provide a near-unity power factor such that output power of the inverter is more efficiently provided. Additionally, the 115 volt inverter is constructed such that for short periods of time, the inverter may output power at a level that exceeds its power rating.

  • Constant current welding power supply with auxilary power source to maintain minimum output current levels
    Patent number: 5218182
    Abstract: An auxiliary power supply is connected through a fast acting switch to the output of a regulated, constant current welding power supply. A current sensing circuit monitoring the output current level actuates the fast acting switch whenever the current level falls below a predetermined value to insure that a minimum output current level is maintained. The auxiliary power supply is disconnected after the current level rises to a second, higher current level.
