Gas welding equipment. Pressure regulators and pressure regulators with flow-metering devices for gas cylinders used in welding, cutting and allied processes up to 300 bar (30 MPa)What is ISO 2503 Gas welding equipment about? ISO 2503 discusses gas welding equipment. Gas welding equipment is among the most essential tools for a welding professional. Welding machines generate heat that melts metal parts so that these parts can be joined. ISO 2503 specifies requirements for single or two stage pressure regulators without flow metering devices for connection to gas cylinders used for: Compressed gases up to 300 bar1) (30 mpa)
