RE: low posoity with APS
That’s Ok, if you use 8mm nozzle remember to use 2mm injector, because with the reduction of the gas speed, is necessary to reduce the powder speed, this if you use F4 gun, if you use 3MB gun, you could use N/H2 parameters, with feed rate 46gr/min instead of 60, the best result were obtained using nitrogen as primary gas, it is very important to check the perfect electrode alignment, and a perfect alignment of the powder stream in the flame, this is do with accuracy, in order to eliminate unmelted particles.
