Harris® 6290-VVC Size 6NH is a two-piece, propane/natural gas, Unplated machine cutting tip. It cuts up to 11 in. thick plate at a cutting speed of 4 in. per minute (I.P.M.) and requires 60 PSIG of cutting oxygen, 30 - 40 PSIG low-high oxygen preheat and 4 oz. - 2 PSIG of preheat fuel. This tip has a 690 SCFH cutting oxygen flow rate, 50 - 100 SCFH low preheat oxygen flow rate, 20 SCFH propane flow rate or 50 SCFH natural gas flow rate for cutting metals. The approximate kerf is .25 in. Best when used with Harris machine cutting torch model 98-6F.
