Stream breaks up or flares
A chipped or worn orifice gives a ragged, spreading jet and a wider kerf. A diamond orifice holds its edge far longer than ruby or sapphire, but it still wears or chips over time.
Cut quality drops
Taper, striations and slow cutting with a good mixing tube and abrasive feed point to the orifice.
Pressure changes
A worn orifice lets pump pressure fall at the same flow. Check it when the pump runs at full stroke rate but pressure is low.
Fitting tips
Bleed the high pressure first. Clean the seat in the nozzle body, fit the orifice the right way up, tighten to the head maker's figure and check the stream on a test cut.
