Of all the myths surrounding laser technology, believing that higher air pressure can produce better cutting results attracts many to spend money needlessly. We all have an instinctive notion about how compressed air behaves, but led by the many YouTube "experts", those new to this technology forgo logic and spend money needlessly upgrading to an expensive less efficient system of air assist.
This session digs into the physics relationship of pressure and flow in compressed air and demonstrates the way in which air assist is REALLY used for cutting. The 30psi panacea profferd by many upgraders is a myth because, as demonstrated, the effective nozzle pressure is only 2 or 3psi. The simple aim of air assist is to get an effective efficient flow of air THROUGH a 0.1mm/0.2mm wide kerf.
