hard water
Water with dissolved minerals in it, typically calcium and magnesium
high-pressure mode (cut-pressure mode)
Water that is at cutting pressure
high-pressure water
Water that has been pressurized by the intensifier for cutting or piercing
hose
A flexible tube that carries low-pressure fluid
inlet cutting water (cutting water in)
Low-pressure water from a softener or reverse osmosis system that goes to the intensifier
ISO
The International Organization for Standardization is an independent membership organization that develops
voluntary standards
JIC
JIC (Joint Industry Council) fittings are a type of flare fitting used in fluid delivery applications; these fittings are

2
lap
To rub a stainless steel surface against lapping paper to make the surface very smooth and flat
lockout-tagout
Lockout-tagout procedures protect workers from the unexpected starting of machinery and equipment and the
release of hazardous energy during maintenance or repair activities.
low-pressure mode (pierce-pressure mode)
Water that is at a reduced pressure that is used to pierce the material to be cut; using a lower pressure prevents
brittle materials from cracking
low-pressure water
Water that is not pressurized by the intensifier
NPT
National pipe thread taper, a common United States standard for tapered threads that are used on fittings and pipes
OEM
