Servo spot welding uses an additional servo motor and encoder (7th axis) of the robot to drive and control the clamping force of the welding electrodes. Using a spare robot axis to actuate the weld gun gives added benefits than a pneumatic weld gun. First, a wider range of clamping pressures can be controlled for different materials and thicknesses. Reduced cycle time can be achieved by having full control of the stroke of the weld gun. Along with this, it gives a low impact condition when contacting the work piece at the beginning of a weld sequence. This gives a longer life span of the electrodes. Another benefit would be that it is much quieter than a pneumatic weld gun. Also, less expulsion results from servo spot welding.

Both of these weld guns can be gun changer compatible. This means that one operation can use more than one weld gun per robot.

Pedestal welding uses a fixed spot welding gun and a robot with a material handling end effector. The robot manipulates a part through the pedestal welding gun. This allows for material handling and spot welding with only one robot and no gun changer. This weld gun can be either pneumatic or servo. Kawasaki has special software features to simplify programming in this configuration.
