VVC Machine Cutting - Harris Style 6290 VVC Cutting Nozzles
Noz-Alls own Harris style 6290 VVC - A high speed cutting tip most commonly used for machine cutting. The VVC is chrome plated to help provide some protection against spatter adhesion. When using high speed nozzles which have a convergent / divergent cutting bore, like the VVC, it is important to operate at the correct cutting oxygen pressure which should be measured at the torch inlet connection.
These nozzles are designed to perform as good or better than the original VVC, we have made changes to our design and some settings will need to be adjusted to attain the best performance.
