Yes, pressure systems require appropriate nozzles sizes.
The AR675 as build to meet specifications rating, is using a variable wand with a 1.2mm orifice. If you chose to purchase a wand and convert the connection to Quick Connect (QC) ball coupler. You would be looking for a #3.0 - #3.5 Nozzle.
The pressure systems example I like to use is, hold your thumb over a garden hose when it is turned on. You can regulate pressure by moving your thumb. Pressure systems act the same way. If you completely remove your thumb the water flow is at its max. However it will have little pressure over the column pressure from the well pump or city tower you are using. Similarly, when you fully cover the hose end you ultimately reach max pressure (PSI). The restriction on flow increases pressure ( Nozzle Size), depending what you are using a pressure system for you are ultimately trying to find the balance between Pressure and Flow for your application and machine capacity.
Without it being said, you CANNOT, have max pressure and max flow at the same time.
