FAQ

A standard pressure regulator controls the outlet pressure (in bar or psi), while a flowmeter regulator, like this Harris 801, controls the outlet flow rate (in Liters per minute). This is crucial for welding, where a consistent shielding gas flow is required.

This regulator is specifically designed and calibrated for Argon. Using it with other gases, especially CO2 or mixed gases, will result in inaccurate flow readings and potentially unsafe operation. Always use regulators matched to the specific gas type.

For safety and accuracy, gas regulators should be visually inspected for leaks and damage before each use. Professional testing and servicing are recommended at least every 5 years, or more frequently depending on usage and local regulations.
