| Note: Data compiled using mild steel as test material. * Applicable for three hose machine torch only. With a two-hose cutting torch, pre-heat pressure is set by the cutting oxygen. ** For best results use ST2600FC series torches and 3/8" hose when using tip sizes 6 or larger. *** All pressures are measured at the regulator using 25' x x1/4" hose through tip size 5 and 25' x 3/8" hose for tip size 6 and larger. ****Oxygen consumption is 1.1 times the acetylene under neutral flame conditions. WARNING: At no time should the withdrawal rate of an individual acetylene cylinder exceed 1/7 of the cylinder contents per hour. If additional flow capacity is required use an acetylene manifold system of sufficient size to supply the necessary volume. |
