Abstract
A welding device includes a holder for a weld part (1) adapted to be moved substantially perpendicularly to, and away from, a surface of a workpiece (2) on which the weld part (1) is to be welded. An arc producing system produces an arc between the weld part (1) and the surface of the workpiece (2) with the arc generating a magnetic flux. A field former (3) includes a low-retentivity steel and provides a flux path for the magnetic flux generated by the arc.
