water cutting

So I sent of to ESAB cutting systems to get some samples, but they never came! O well. What interested me was the water jet cutting system. By what I can gather it can cut like a plasma and laser cutting. It even mentioned stone! The machines are giant and can be converted to plasma cutting as well as water. Beyond that there wasn't much interesting information the site besides the specks of the machines. I'm really sad I didn't get my samples.
