Abstract
Official abstract text for this publication.
A system and method is provided in which a surface tension transfer welding function is employed where the welding waveform switches polarity during welding when a short circuit event is detected.
First claim
Opening claim text (preview).
What is claimed is: 1. A short circuit welding power supply, comprising: a switching power supply which provides a welding current waveform to at least one workpiece to be welded, where said welding current waveform comprises a plurality of welding cycles and each of said welding cycles comprises at least an arc portion and a shorting portion which is initiated after the detection of a short circuit between an electrode and said at least one workpiece; and a controller which con…
