A welding device includes a holder for a weld part ( ) adapted to be moved substantially perpendicularly to, and away from, a surface of a workpiece ( ) on which the weld part ( ) is to be welded. An arc producing system produces an arc between the weld part ( ) and the surface of the workpiece ( ) with the arc generating a magnetic flux. A field former ( ) includes a low-retentivity steel and provides a flux path for the magnetic flux generated by the arc.
