OPERATOR'S MANUAL ENGLISH - Kubota

The maximum working pressure for acetylene gas when using a cutting torch is 15 psi or 103.4 kPa. If the pressure goes beyond that, raw acetylene gets unstable and becomes dangerous to use. Acetylene is a flammable gas and when it becomes unstable, it is at risk of spontaneously combusting.

Oxy-fuel cutting is a thermal cutting process that uses oxygen and fuel gas (such as acetylene, propane, MAPP, propylene and natural gas) to cut through materials. The oxyfuel process is the most widely applied industrial thermal cutting process because it can cut thicknesses from 0.5mm to 250mm, the equipment is low cost and can be used ...

Aug 20, 2012 · With 1 bar and a nozzle of 1.5mm, oxygen flow is about 85 ft3/h or 2407 l/h, or about 40 l/min. So if it takes 1 min to cut the part, you would use about 40 l of gas oxygen. 1 liter of liquid oxygen will expand to about 800 liters of gas oxygen. So your cost would be about 0.55p/800 * 40 = 0.03p

Nov 26, 2012 · Cutting with Nitrogen, however, uses a technique known as fusion cutting. With this process, the laser melts the material and the high pressure Nitrogen ejects the material through the cut. Because Nitrogen is an inert gas, it does not react with the molten metal and therefore your cut is much cooler than if it was cut with Oxygen.

Automatic Gas Profile Cutting Machine - Portable shape ...

Limitations of Gas-Cutting: (i) Gas cutting only successfully used when the oxidation (ignition) temperature of the metal being cut is lower than it melting point. (ii) Therefore, oxy-fuel cutting is not recommended for the cast iron because its ignition temperature is higher than its melting temperature.

Jun 22, 2021 · The equations for delta V and mass ratio are slightly different for a Solar Moth or Laser Thermal rocket engine: Δ v = sqrt((2 * Bp * Bε) / mDot) * ln[R]. R = e (Δ v /sqrt((2 * Bp * Bε) / mDot). where. Δ v = ship's total deltaV capability (m/s); R = ship's mass ratio; Bp = Beam power (watts) of either laser beam or solar energy collected; Bε = efficiency with which engine converts beam ...
