In the gas welding process, gases such as oxygen and acetylene are stored in high-pressure cylinders and delivered to the torch through pressure regulators.
Hose pipes serve the function of transporting these gases from the regulators to the welding torch at controlled pressures.
These hoses are made from flexible, durable material capable of withstanding internal gas pressure.
- Red hose: used for acetylene (fuel gas)
- Blue/Black hose: used for oxygen
Hose pipes do not perform mixing, eye protection, or oxide removal:
- Mixing of gases occurs in the mixing chamber of the torch.
- Eye protection is provided by welding goggles or helmets.
- Oxide film removal is done using flux or mechanical cleaning tools.
