Best Harris Welding Gas Regulators in 2026

Brand New BETOOLL Argon / CO2 regulator and flow meter.

Flow Meters are more accurate than the flow gauge regulators.

The pressure gauge which shows how much gas is left in the tank goes from 0 to 4000 psi.

Argon/CO2 Regulator For Welding: Zistel Argon Regulator is a ideal choice for professional TIG/MIG welding applications, which can be used to reduce and control pressure levels.

Argon Flowmeter With Pressue Gauge: Our argon flowmeter is equipped with pressure gauge, allowing you to view how much gas is left in the tank range 0 to 3500psi.

CGA580 Inlet Connection: Zistel pressure regulator is suitable for standard Argon /O2/N2 Tanks with CGA-580 Inlet Connection. You can connect the welding hose via female 5/8UNF-18RH fitting.

Designed for light and medium MIG and TIG applications

Provides accurate flow of gas

Dual scale-gauge with impact resistant polycarbonate lens and machined brass body for maximum durability

CGA580 CONNECTION - The argon regulator/flowmeter is suitable for standard Gas tanks like argon, CO2, and helium with CGA-580 inlet connection, and has a unique filter port design on the CGA-580 mounting port.
