YES…, it has an analog input to which we can connect a voltage output of the robot . Each volt applied to the input  is 10 liters / minute. In this way the different flow rates to be applied are unlimited or even generate increasing or waning gas ramps.
In the same way as the robot  , or robotic installation , is the one that controls the welding current , now the robot can also adjust the required gas flow ,  independently of the welding current , with fully flexibility … it can receive the gas setpoint digitally or analog way
