Components of the Welding Head

The basic body of the welding head KAH 412 is made of an aluminum square.
All supply lines are plugged in the connection casing (welding current cable, control
cable, air pressure hoses).
At the front side of the welding head KAH 412 the slot tube is located, which may be
quickly replaced by means of the stop spring. Supplying the welding fittings to the chuck
(manually or automatically) is done through the slot tube with guide bushing. The plunger
cylinder, which is integrated in the piston and equipped with linear ball bearings with zero
backlash, transports the fitting pneumatically through the chuck in welding position.
Above the connection casing, the complete adjusting mechanism for lift-off and spring
force is positioned. The spring force is directly displayed on a scale.
Attaching the welding head KAH 412 in Z-direction is done with the quick-change prism
system, which is mounted on the backside. The fixture is performed pneumatically or
motor-driven, depending on customer's needs.
