OVERVIEW

Reliable Pressure Monitoring for Industrial Regulators

The Techniweld C400 is a precision replacement pressure gauge designed to restore the functionality of your gas regulation equipment. Featuring a compact 1-1/2 inch dial, this gauge is engineered to fit standard welding regulators where space and readability are paramount. The scale reads from 0 to 400 PSI (pounds per square inch), making it an ideal choice for specific pressure monitoring applications within the welding and industrial gas sector.

Constructed with durability in mind, the C400 features a robust case that protects the internal mechanism from the daily wear and tear of shop environments. The 1/8-inch NPT bottom mount connection is the industry standard for this size of gauge, ensuring seamless compatibility with a vast array of regulators from various manufacturers. Whether you are monitoring delivery pressure on an oxygen line or checking cylinder pressure on an acetylene tank, accuracy is critical for safety and process quality.

Replacing a damaged gauge is a simple maintenance task that ensures your equipment remains compliant and safe to operate. A clear, functioning gauge allows operators to verify gas flow and detect potential leaks or supply issues immediately. This unit is cleaned for oxygen service, meaning it is free from oils and contaminants that could pose a hazard in oxygen-enriched environments, although it is versatile enough for use with inert gases as well.

FAQ

The gauge features a 1/8" NPT (National Pipe Taper) male thread, which is the standard connection for most 1.5" welding regulator gauges.

Yes, welding gauges like the C400 are typically manufactured 'cleaned for oxygen service' to ensure safety, though you should always keep the threads free of oil and grease during installation.

Yes, a 0-400 PSI gauge is often used to indicate the cylinder pressure on acetylene regulators, as acetylene cylinders are pressurized to approximately 250 PSI.

Unscrew the old gauge using a wrench on the brass square stem. Apply a small amount of oxygen-safe thread sealant or Teflon tape (starting one thread back) to the new gauge, and tighten it into the port using a wrench on the stem. Do not tighten by gripping the round case.

The dial diameter is 1-1/2 inches, making it a compact option suitable for most standard regulators.

The '400 lb' marking indicates the maximum pressure reading of 400 PSI (Pounds per Square Inch).

If the flowmeter has a pressure gauge port with 1/8" NPT threads requiring a 0-400 PSI range, yes. However, many flowmeters use calibrated tubes rather than pressure gauges for flow, so check your specific equipment.

These gauges typically feature a painted steel case for durability in industrial environments.
