Just adjust the oxygen level to about 0.25-0.3MPa. Acetylene can be adjusted to 0.05-0.1MPa.
This depends on the size of the cutting torch or welding torch, cutting nozzle or welding nozzle used to determine the pressure value adjusted by the pressure reducer. The larger the model of cutting torch or welding torch used, the larger the cutting nozzle, and the larger or thicker the workpiece to be cut or welded, the adjusted pressure value needs to be increased appropriately.
Generally, there are relevant pressure values ??and other parameters on the packaging box of the new cutting torch or welding torch for reference.
Extended information
Since the pressure inside the gas cylinder is high, but the pressure required for gas welding and gas cutting and the point of use is small, a pressure reducer is needed to reduce the pressure stored in the gas cylinder. The higher pressure gas in the bottle is reduced to low pressure gas, and the required working pressure should be ensured to remain stable from beginning to end.
According to different uses, acetylene pressure reducers can be divided into oxygen pressure reducers and acetylene pressure reducers. They can also be divided into centralized type and post type; according to different structures, they can be divided into single-stage and There are two types of double-stage type; according to different working principles, they can be divided into two types: forward-acting type and reaction-acting type. At present, the common domestic pressure reducers are mainly two types: single-stage reaction type and two-stage hybrid type (the first stage is a forward-acting type and the second stage is a reaction-type).
