These "one size fits all" suggestions for Oxy/fuel settings is simply ridiculous and the Oxygen pressure needs to be set for the task at hand, are you saying you cut 1/4" plate with 40 PSI Oxygen? How about 1/8" plate? What about 6" plate even with a large tip? Sure 40 PSI CAN work in a lot of situations but there are a heck of a lot more where a lot less pressure, or more pressure, would work a lot better. Using 40 PSI on thin plate is going to waste a lot of Oxygen and with the right (small tip) it is going to make a poor cut! Fellas there IS NOT ANY ONE SETTING FOR OXYGEN! Even Acetylene sometimes needs more than 7 PSI although for the vast majority of jobs that setting would be fine, try using a no. 6 (Victor) tip to cut 6" plate with only 7 PSI on the fuel gauge, might work if you have 1/2" hose! Learn to set the Oxygen pressure to whatever works properly for what is being done and I would think that for what most of the guys here would be using a torch for 40 PSI Oxygen is simply way too high, even if it works ok you would be wasting a lot of it on thin plate.
