Acetylene welding flashback preventer (also commonly referred to as “flashback preventer” or “flashback prevention device”) is a crucial safety equipment.core functionIts core function is only one: to prevent flame backfire from entering acetylene cylinders or pipeline systems, thereby avoiding severe explosion accidents. 1. What is “tempering”?In gas welding (especially oxygen acetylene welding), tempering refers to

First level depressurization: Reduce the high pressure (e.g. 15 MPa) inside the gas cylinder to a stable, lower medium pressure (e.g. 0.5-0.8 MPa). Secondary pressure reduction and stabilization: When you adjust the knob of the flowmeter, the pressure regulator ensures stable output pressure and flow rate, even if the cylinder pressure gradually decreases with use,

Argon is one of the most widely used shielding gases in welding because it is an inert gas that can effectively protect the molten pool from air pollution.Simply put, the vast majority of common metals and alloys can be welded using argon gas, especially the TIG welding method.Below, we will provide a detailed explanation by

In welding, we usually do not directly set and monitor the pressure of CO ₂, but focus more on and control the flow rate.This is because the pressure during transportation will vary due to the length of the pipeline and the number of joints, while the flow rate directly determines whether the amount of gas

Carbon dioxide (CO ₂) can partially or completely replace expensive argon gas (Ar) in welding, mainly in MAG welding (active gas shielded welding).

Choosing an argon pressure reducer for welding is a very practical issue. argon gas is an inert gas that is always in a gaseous state, making it easier to choose, but there are still key points to note. Single gauge pressure regulator (only with output pressure/flow meter)1. Characteristics: There is only one meter head, usually

The choice of CO ₂ pressure reducer for welding (more accurately referred to as CO ₂ arc+CO ₂ pressure reducer) is very important, as it directly affects the stability of gas output and welding quality. The following are the key points for selection, you can refer to this process to choose: 1、 Firstly, confirm the
