Poor stream or wide kerf
A worn orifice, mixing chamber or mixing tube all show up as a wider, rougher cut. Swapping the whole nozzle assembly gets the machine cutting again while the old one is checked.
Abrasive blockage
A nozzle that blocks with abrasive again and again often has a damaged orifice or chamber inside. A spare assembly keeps the machine running.
Spare for the cutting head
Shops keep a ready nozzle assembly so an orifice failure costs minutes, not a shift.
Fitting tips
Bleed the high pressure, clean the inlet body seat, fit the assembly with the filter in place, tighten to the maker's torque and test cut on scrap.
