Types of argon regulators
1. Pressure-gauge regulator
Shows cylinder pressure and outlet pressure.
Useful for general gas control.
Often used with a separate flow meter.
2. Argon flowmeter regulator
Measures gas flow in L/min.
Common for TIG and MIG welding.
Typical welding flow is around 8–15 L/min, depending on the process and torch.
Typical specifications
Specification Common range
Cylinder pressure Up to about 200–300 bar, depending on cylinder
