Twin Welding Hose：Oxygen/Acetylene

Double-head welding hose is the “lifeline” connecting oxygen cylinder, acetylene cylinder and welding torch/cutting torch. Its application directly serves the following processes:

1. Gas welding: The high-temperature flame produced by the mixed combustion of oxygen and acetylene is used to melt the base material and fill the welding wire, enabling the connection of metals (primarily steel, cast iron, copper alloys, etc.). The twin welding hose delivers the two gases to the welding torch as needed and safely. With the flame properties and heat adjusted via valves on the torch.
2. Gas cuts: This is the main application. The metal is preheated to ignition point by an oxygen-acetylene flame, and then a high-speed pure oxygen flow is sprayed into the preheated area, causing the metal to oxidize (burn) violently and blow away slag to form a cut. Twin welding hose delivers the oxygen/acetylene mixture required for preheating the flame as well as the high pressure air flow of pure oxygen required for cutting to the torch.
