摘要： An electric arc device and methods to build up, clad, join, or overlay an alloyed metal onto a parent metal with minimal admixture. The methods employed in the electric arc device provide a high frequency waveform with a high amplitude pulse, a low amplitude background current, and a special shorting routine, to alleviate the problem of generating too much ad-mixture. A fast transition from a peak current level to a background current level along with a shorting response and a plasma boost pulse reduces the droplet size and reduces the heat input required to achieve good welding performance.

摘要： An electric arc welder for performing a pulse welding process by a current between an advancing electrode and workpiece where the welder comprises a short detecting circuit for creating a short signal upon occurrence of a short circuit between the advancing electrode and the workpiece and a boost circuit to create a plasma boost pulse after the short circuit is cleared during the time period when the welder is not outputting the peak pulse current.
