Page 8: Arc Starting And Arc Burning
3.1.5 Arc Starting and Arc Burning Arc Strike Always start the arc in the welding groove. When the arc is stable weld over the arc strike and melt for good fusion, otherwise there is a risk of cracking. wrong arc strike correct Arc Length The arc length "a", that is the distance between the stick electrode and the work, should be:... -
Page 9: Welding Hints
Welding Hints Because of the multitude of and great differences in the important points for welding only the very basic operations for the most common electrodes for low-carbon steels, the Ti-type electrode, are introduced here. In the case that other electrodes have to be used, the electrode manufacturers supply upon request all relevant information for the type of special electrode to be used. -
