C-200 - 1-1/2 Inch Replacement Regulator Gauge, 0-200 PSI, Bottom Mount

Precision Pressure Monitoring for Industrial Applications

The Techniweld C-200 is a high-quality replacement pressure gauge designed to provide accurate readings for industrial gas regulators and pneumatic systems. Featuring a compact 1-1/2 inch dial face, this gauge is engineered to fit within the protective housings of standard welding regulators without compromising readability. The scale ranges from 0 to 200 PSI, making it specifically suitable for monitoring delivery pressure (low pressure) on various gas regulation equipment. The clear, high-contrast markings ensure that operators can verify pressure settings at a glance, contributing to process consistency and safety.

Standardized Connection and Compatibility

Equipped with a 1/8 inch NPT bottom mount connection, the C-200 adheres to the industry standard for compact regulator gauges. This National Pipe Taper thread ensures a secure, leak-resistant seal when installed correctly with appropriate thread sealant. The bottom mount configuration allows the gauge to sit vertically on top of the regulator body, the most common orientation for welding setups. This standardization makes the C-200 a versatile inventory item, capable of servicing a wide array of regulators from different manufacturers used in MIG, TIG, and oxy-fuel processes.

Durable Construction and Reliability

Built to withstand the rigors of the industrial environment, this gauge features a robust case that protects the internal mechanism from minor impacts and dust. The internal movement is calibrated to provide reliable feedback, essential for maintaining the correct flow rates in shielding gas applications. Whether used for Argon, CO2, or mixed gases, maintaining the correct delivery pressure is critical for weld quality. A functioning gauge like the C-200 allows for precise adjustment of the regulator diaphragm, preventing issues such as porosity caused by inadequate gas coverage or turbulence caused by excessive pressure.

Installation and Maintenance

Replacing a damaged gauge is a straightforward maintenance task that restores the functionality of expensive regulation equipment. The C-200 is designed for easy installation using standard wrenches. Users should ensure the system is fully depressurized before removal of the old gauge. When installing the C-200, force should be applied only to the brass wrench flats at the stem, never the case, to prevent misalignment of the internal mechanism. This attention to detail ensures the longevity and accuracy of the gauge in service.
