Classification: CPC B | IPC B

Claim 15:
16. The welding device according to claim 15, wherein:
the feed controller is configured to determine a short circuit between the welding wire and the workpiece via the detected electrical potential;
when the short circuit is detected, the feed controller is configured:
to stop the supply of welding wire at a first welding wire feed speed by the welding wire feed; or
to change the supply of welding wire to a second welding wire feed speed;

the feed controller is configured to determine, via a tapped electrical potential and a specified limit value of the electrical potential, that the stopped welding wire has melted to a certain extent causing elimination of the short circuit, whereby the feed controller restarts the supply of the welding wire into the region of the electrode.
