Miller® CO2 (Carbon Dioxide) Flowmeter Regulator 22-80-320
The Miller® CO2 (Carbon Dioxide) Flow Meter Regulator is ideal for most MIG welding applications where accurate delivery of CO2 shielding gas is desired. The flow tube features Miller's exclusive self-centering ball guide, which delivers more precise readings of shielding gas flow than competitive brands; saving on shielding gas cost. The flow tube also has a high-visibility green-scale background and is protected by a robust aluminum housing.
The 22-80-320 flow meter comes with a GGA-320 (CO2) inlet and has a preset outlet delivery pressure of 80 PSIG. The flow range for this regulator is 10-80 SCFH. It is backed by Miller's True Blue® Three Year Warranty.
Rugged aluminum housing protects flow tubes from accidental damage while offering an
unobstructed view of flow reading.
Extra-long flow tube. Expanded scales are easy to read and accurate within five percent
of full scale reading.
High-visibility-green scale background eases reading flowmeter from a distance and in
Shatter-resistant multi-scale flow tube. Tubes are made of shatter-resistant polycarbonate
resin and feature separate scales for argon, C02 and helium depending on the model.
Unique self-centering ball guide - exclusive ball-centering flow tube provides accurate flow readings even if the tube is tipped. This ensures good weld quality and gas savings. Non self-centering flow tube ball tends to float off center. Actual gas flow can be up to 2-1/2 times greater than is indicated.
Two-inch cylinder pressure gauge is easy to read and has a shatter-resistant lens.
Auto-reset pressure-relief valve protects regulator
from damage due to inadvertent high-pressure surge.
Relief valve will release excessive pressure and
