4.1.3 Marking Configuration. The style and location of (he markings are left to the manufacturer to establish. The markings must include the manufacturer’s identification and model number (part number) or code, e.g., CT 12-0, followed by the fuel gas identification and then the maximum cutting capacity of (he nozzle, e.g., A 6 mm. Example:
Acme Mfg. CT 12-0 A 6 mm. If necessary, more than one line may be used to mark the information on the nozzle.
4.2 Safety and Health Requirements. The manufacturer shall make available the detailed instructions for the proper settings of the cutting nozzles. This information must include the recommended pressure settings in kilopascals (kPa) and the flow rates in liters per minute (Llmin) for the oxygen and fuel gas required. These settings should give the operator acceptable performance under normal operating conditions.
The manufacturer shall make the safety information available for the proper use and operation of the cutting nozzle and related equipment used for oxyfuel cutting. This information should be in the form of instruction literature or imprinted on the Product packaging.
5. Welding Nozzles
This clause applies to all oxyfuel welding nozzles used with a welding torch for the purpose of welding metals.
5.1 Marking. The marking shall be legible and durable. All nozzles or mixing sections shall be marked with the name, registered trademark, or identifying mark of the manufacturer, with the symbol identifying the fuel gas, the welding nozzle capacity, and with a code to permit easy reference to the manufacturer’s operating data.
5.1.1 Fuel Gas [)esignation. The fuel gas shall he imprinted per the abbreviations in Table 1. When a nozzle may he used with multiple fuel gases, the abbreviations for all applicable gases shall he marked on the nozzle. Example: A[1 or PY.
5.1.2 Welding Capacity. The nozzle or mixing section shall he marked with the maximum welding capacity in millimeters. This rating should be the maximum material thickness that the nozzle will effectively weld under practical conditions. This rating is the responsibility of the manufacturer to establish Example: 6 mm.
5.1.3 Marking Configuration. The style and location of the marking is left to the manufacturer to establish. The marking must include the manufacturer’s identification and model number (part number) or code, e.g., WT208, followed by the fuel gas identification and then the maximum welding capacity of the nozzle, e.g. A 6 mm. Example: Acme Mfg. WT 208 A 6 mm.
The mixing section that is used with the welding nozzle shall he marked with the manufacturer’s identification, model number (part number) or code, and the fuel gas for which it is designed. It may he necessary to use more than one line to mark this information on the nozzle and/or mixing section.
5.2 Safety and Health Requirements. The manufacturer shall make available detailed instructions for the proper settings of the welding nozzles. This information must include the recommended pressure settings in kilopascals (kPa) and the flow rates in liters per minute (11mm) for the oxygen and fuel gas required. These settings should give the operator acceptable performance under normal operating conditions.
The manufacturer shall make the safety information available for the proper use and operation of the welding nozzle and related equipment used for oxyfuel welding. This information should be in the form of instruction literature or imprinted on the product carton.AWS C4.5M pdf download.
