WELDING POWER SUPPLY ARC STARTER |
摘要 |
A method and apparatus for arc welding, particularly starting an arc is disclosed. A welding power source that provides a welding current to an electrode and a workpiece includes a source of welding current having an inductor. The inductor and current source are connected to a pair of outputs, such as the output studs, and form a welding current path including the source of current, the output inductor, the outputs and the electrode and workpiece. A source of a high frequency voltage, such as a high frequency coupling coil is included in the welding current path. An arc starting circuit provides a controllable current path for current flow in the inductor prior to the application of high frequency voltage. The arc starting current path is not the welding current path.
