... to be the next generation of cold gas systems. However, the gun dimensions of more than 1.2 m (4 ft) in length and a weight of almost 50 kg (110 lb) necessitate that the robot handling gun is capable of high load-bearing capacity. Over four units have been installed worldwide and are used primarily...
