Frequently Asked Questions
What gases can the QTYH-20 pressure regulator handle?
The regulator is suitable for common welding gases such as oxygen, acetylene, LPG, and inert gases like argon. Always verify gas compatibility with the gasket and internal materials.
Does the regulator come with a pressure gauge?
Yes, the QTYH-20 is equipped with high-pressure and low-pressure gauges to allow accurate monitoring of cylinder pressure and outlet pressure.
What is the maximum inlet pressure?
The maximum inlet pressure is 25 bar (360 psi), which covers most standard compressed gas cylinders used in marine welding applications.
Is the QTYH-20 suitable for saltwater environments?
The brass body and corrosion-resistant internal parts make it suitable for use in marine atmospheres. We recommend rinsing with fresh water after exposure to salt spray to extend its lifespan.
