Outdoor Working Manual Ignition Butane Gas Torch Working Principle

- Aug 29, 2018-

  Outdoor use of manual ignition butane gas torches during installation and maintenance: Gas welding and gas cutting equipment are often required, such as round steel, steel and steel structural parts cutting, heating, high-voltage cable termination, fire, etc. Outdoor use manual ignition butane gas torch working principle is to open the torch oxygen valve, acetylene valve, a certain pressure of oxygen into the nozzle through the catheter, and high-speed injection into the straw, so that the space around the nozzle creates a vacuum, thus the acetylene tube acetylene The suction suction pipe is mixed by the mixing pipe, and is sprayed by a welding nozzle (cutting nozzle), and a high-temperature flame generated when the oxygen gas and the acetylene mixed gas are burned is used to melt the welding wire and the weldment. The flow of acetylene in the torch mainly depends on the injection of oxygen, so the use of low pressure and medium pressure acetylene can make the torch work normally.

  The outdoor working manual ignition butane gas torch works in the same way as the injection-type welding torch (see attached figure, the basic parameters are shown in the table below). The difference is that the torch body and the cutting nozzle structure are slightly different. Gas cutting is a high-temperature flame generated by burning a gas mixed with oxygen and acetylene, heating the metal to be cut to a melting temperature, and then ejecting a high-pressure oxygen jet to blow off the melted dross.

  After using the manual ignition butane gas torch to inject the suction condition and the performance check, the acetylene hose can be installed on the torch or the torch acetylene inlet connector to enter the ignition program. When the torch or torch is ignited, the oxygen regulating valve should be opened slightly, and then the acetylene valve can be opened to ignite. After the ignition is successful, the mixed flame is adjusted and adjusted to the neutral flame (welding torch) to be welded. If a torch is used, the flame should have a contoured core and a normal flame length, then try the high pressure oxygen regulator to adjust to normal flame for cutting.
