Arch CO2 Brass Gas Regulator (Heavy Duty Dual Gauge)

Arch CO2 Dual-Gauge Regulator: Robust Single-Stage Precision

The Arch CO2 Brass Regulator is the industry standard for reliable gas delivery in MIG welding. Featuring a Single-Stage design, it offers a simplified, robust internal mechanism that is less prone to maintenance issues while providing the accuracy required for professional fabrication.

Dual Gauge Monitoring for Maximum Control

Even with its streamlined single-stage operation, this regulator provides full transparency for the operator. The left gauge indicates the remaining pressure in your CO2 cylinder, while the right gauge (Flow Meter) allows you to set the exact Liters Per Minute (LPM) required for your weld pool.

Why Choose the Arch Single-Stage Series?

• Forged Brass Construction: The high-density brass body resists “CO2 freezing” during long weld cycles, ensuring the internal diaphragm remains flexible and responsive.

• Sintered Bronze Filter: A built-in high-grade filter at the inlet prevents cylinder debris from entering the regulator, extending the life of your gas solenoid on the welding machine.

• User-Replaceable Gauges: Standard thread sizes allow for easy gauge replacement in the event of accidental damage on a busy job site.

• Self-Seating Safety Valve: Features an internal relief valve that automatically vents excess pressure, protecting both the operator and the equipment.
