Why Go Servo Gun

Servo Control Offers Major Benefits Over Pneumatic

• Improved weld quality as expulsion is minimised and force is stable.

• No guessing force as closed loop feedback on pressure.

• No welding on rising pressure that is possible with Pneumatic systems.

• Force is maintained with a few percent for whole of life.

• Low maintenance and longer life (typical 4 times longer than cylinders).

• Wide spectrum of controlled force so can be used across a range of guns.

• Minimises panel damage as softer approach ( software dependant).

• Automatic re calibration of TCP after tip dressing ( software dependant).

Production

• Faster processing time , Weld can fire as soon as pressure attained.

• Gun opening totally controlled to optimum distances.

• Sheet metal thickness detection.

• Gun opening distances can be optimised for each component condition.

• Less noise for operators so improved working conditions.

• More reliable as no external position sensors ( high lift) or air valves.

Cost Savings

• The production of air is very expensive and inefficient ( that’s apart from air leaks in factories) typically servo units are about 80% efficient while pneumatic systems are only 15 to 20% efficient.

• Guns last longer due to less impact forces.
