Water pressure upgrade from 0.5 to 8 bar, cutting thick workpieces now a piece of cake!

I”ve upgraded the water pressure of the C-arc nozzles. The original design used a water pump from a dish washing machine that could only reach 0.5-1 bar max. Now I use a heavy duty industrial pump that reaches 8 bar. This give an enormous performance increase in cutting workpieces, most notably in cutting aluminum. Before the upgrade, very thick aluminum just would not cut without breaking the wire (cutting steel was no problem). My machine can now cut very thick material. In initial high pressure tests 60mm thickness cuts like a dream.

Here’s a picture of a small cut and a notch through a 60mm thick aluminum workpiece.

This is the used pump:
