Having high-quality pressure regulators is essential for all welding, cutting, brazing or industrial applications. Pressure regulators designed for oxygen and acetylene must be designed for reliable and accurate flow and pressure control in order to protect equipment and workers.

Oxyacetylene welding is a process used to heat and melt metals in order to join them together. To create a flame that is hot enough (+- 3100 - 3500°), a mixture of oxygen and acetylene is burned. It is impossible to mix the two gases in a single cylinder because acetylene is unstable and oxygen is a powerful oxidizer; mixing the two could cause a very violent explosion.
For this reason, oxy acetylene systems use two separate cylinders, each equipped with specific pressure regulators. These regulators ensure safe gas delivery by reducing the pressure to a stable, usable level to enable the safe use of oxyacetylene.
Both pressure regulators operate on the same principle: the inlet pressure from the cylinder is reduced and stabilized to maintain a constant outlet pressure and flow rate. When using oxyacetylene for welding, it is crucial to maintain a stable flow rate to ensure the safety of people and equipment, as well as the quality of the work. A constant flow rate ensures a stable flame, resulting in uniform metal fusion and clean welding results, regardless of the type of application.
In a complete acetylene regulator set, oxygen and acetylene are supplied separately and are not mixed until they reach the torch, just before the nozzle outlet. The cutting torch is the part of the system which safely creates the gas mixture only at the point of use.
All oxygen regulators have two pressure gauges, one that indicates the pressure in the cylinder and a second that indicates the gas outlet pressure. This allows the user to ensure that the regulator is functioning properly throughout its use.

Oxy-acetylene welding uses a high-temperature flame created by burning oxygen and acetylene to heat and melt metals. It is widely used for welding, cutting, brazing, and heating applications.
Each regulator reduces the cylinder’s high pressure to a stable working pressure and delivers a constant, controlled gas flow. The gases remain separate until they reach the torch, where they are safely mixed to create the welding or cutting flame.
Yes. Each gas has different pressure, flow, and safety requirements, so dedicated regulators are essential.
One gauge shows the cylinder pressure, and the other shows the outlet pressure going to the torch.
