CD Contact welding Mode

A welding stud is first pushed into the chuck of the welding gun. The ignition tip of the element is then placed down vertically at the required point on the workpiece and the gun pressed down until all positioning feet touch the workpiece (this pushes the plunger against the pressure spring). The welding current is then switched on and the welding process started by pressing the start button. The ignition tip evaporates and generates an arc, which melts the face of the stud and the workpiece. The pre-stressed pressure spring then forces the welding element into the weld pool and the arc is extinguished. The capacitors are discharged completely. The weld pool solidifies. This welding process lasts about 2.0 to 4.0 ms. The welding gun can be pulled off the welding element vertically directly afterwards and fitted with a new one.

CD Gap welding Mode

A welding stud is first pushed into the chuck of the welding gun. The gun is then placed down vertically on the workpiece with all positioning feet. When the start button is pressed, the welding element is lifted by a hoisting magnet against a pressure spring. When the end position is reached, the hoisting magnet is switched off and the welding current switched on. The welding element is then moved into the direction of the workpiece by the pressure spring.When the ignition tip hits the surface, a large discharging current flows. This evaporates the ignition tip and an arc is generated, which melts the face of the stud and an approximately equally large area on the workpiece. The welding element then dips into the weld pool, the arc is extinguished and the weld pool solidifies. This welding process lasts about 1 to 2.5 ms. The welding gun can be pulled off the welding element vertically directly afterwards and fitted with a new one.
