Air Cylinder to Servo
Which is better for performing precision welding, a low-friction pneumatic cylinder or a servo motor?
Under the dynamic conditions that occur during weld formation, a good quality welder with a low friction pneumatic cylinder reacts faster, with greater stability and repeatability than most of the servo motors presently in widespread use on resistance welders. The result is more consistent applied electrode force and higher quality welds than achievable with the servo motor-driven system.
