Abstract
Official abstract text for this publication.
A method for controlling and/or regulating a welding apparatus with a welding wire, wherein after ignition of an electric arc, a cold metal transfer welding process is conducted. For creating more various possibilities for controlling heat introduction into the work piece and/or for introducing filler material, it is provided that during at least some short-circuit phases, polarity of the welding current I and/or the welding voltage U is switched, wherein the amplitude of the welding current I and/or the welding voltage U is adjusted to a defined value so that melting-through of the welding wire and the short-circuit bridge, respectively, is prevented. There is also a safe re-ignition of the electric arc when lifting the welding wire off the work piece. It is also possible to reignite the electric arc only by the welding current I and/or the welding voltage U without any auxiliary voltage, at the end of the short-circuit phase or at the beginning of the electric-arc phase.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method for controlling and regulating a welding apparatus and a welding current source, respectively, with a welding wire, wherein after ignition of an electric arc, a cold metal transfer (CMT) welding process is conducted, comprising the steps of: conveying a welding wire into the direction of the work piece until said welding wire contacts the work piece, reversing the direction of movement of the welding wire away from the work piece subsequentl…
