Drawn Arc Stud Welder Admixture (%): 5 %

Our offered this product widely known for their smooth working to heat and solidify copper flexible link manufactured from bunch/stack of copper-foils, used in Electrical and Chemical Industries.

Product Features:
The stud and the ceramic ferrule is loaded into the stud-welding gun. The gun is positioned on the work piece. After gun triggering the stud lifts by producing pilot-arc approx. 1 to 4 mm from the work piece. The lifting way depends on the diameter. Afterwards the main arc is started. The stud front-surface and the work-piece surface in the area of the ceramic ferrule becomes molten. The ceramic ferrule limits the arc area. After an infinitely variable adjustable weld time the stud is pressed by feather pressure in the molten metal and the main current is switched off. After removing the gun from the welded stud, also the ceramic ferrule has to be removed. As a weld result you see a homogeneous connection with calibrated welding fillet.

Besides drawn-arc welding with ceramic ferrule, shielding gas can be also used as a weld-pool protection. The horizontal weld position should be preferred, because there is no ceramic ferrule to hold the molten metal in position.
