Pressure/Material Imbalance
To determine which component is out of balance, check
the color of some sprayed material. Two-component
materials are usually a mix of light and dark fluids, so
the under-proportioned component can often be readily
determined.
When you have determined which component is
under-proportioned, spray off-target, focusing on the
pressure gauge for that component.
For example:
if component B is under-proportioned,
focus on the B-side pressure gauge. If the B gauge
reads considerably higher than the A gauge, the
problem is at the gun. If the B gauge reads considerably
lower than the A gauge, the problem is at the pump.
