摘要： Systems and methods for providing controlled AC arc welding processes. In arc welding power source embodiments, configurations of main and auxiliary bridge circuits allow for the directional switching of the output welding current through the welding output circuit path and selectively provide one or more high impedance paths to rapidly decay the arc current. The high impedance path aids in the low spatter transfer of molten metal balls from a consumable electrode to a workpiece and further aids in the maintaining or the re-establishing of an arc between the consumable electrode and the workpiece when a molten metal ball is transferred.

摘要： Systems and methods providing low current regulation for AC arc welding processes to regulate arc welding performance. In arc welding power source embodiments, configurations of bridge and arc regulation circuits allow for the directional switching of the welding output current through the welding output circuit path and induce a voltage between the electrode and the workpiece of the welding output circuit path that is sufficient to re-ignite the arc during polarity transition of the output current. The arc regulation circuit provides a high inductance level for storing energy, in both polarities, which induces the voltage level for re-igniting the arc during the zero crossing of the output current and provides low end stabilization of arc current.
