This process is suitable for tack welding or joint welding of metal sheets made from steel and CrNi alloys
up to a thickness of approximately 2.5 mm. Metal sheets of different thicknesses can also be welded on
top of one another. As this is a one-sided process, it is also possible to weld metal sheets onto tubular
sections such as round or square pipes. In arc spot welding, the arc melts through the upper metal sheet
and the lower metal sheet is melted onto it. This produces flat, fine-textured welding tacks which require
little or no post weld work, even in visible areas.

The up-slope and down-
slope times should be set to “0” to achieve an effective result.
