SPARC regulator / flow meter combos are great for MIG and TIG welding.
Backed bySPARC'S 2 year warranty against manufacturing defects.
CGA580 connection for standard gas bottles from any supplier.
The output flow is adjustable from 10 to 60 cfh (cubic feet per hour), and is indicated by a ball which moves up and down in the flow tube, so this flowmeter will handle MIG and TIG welding both steel and aluminum. The inlet fitting is CGA580 fitting, so it fits all argon, helium, nitrogen, and argon/CO2 mixed gas tanks. This does not fit straight CO2 cylinders.
The flowmeter outlet will fit both the female 9/16" x 18 nut or the male 5/8" x 18 fitting. You can see the adapter in the picture. It comes with a standard 1/4" barbed fitting. If you have a Miller, Lincoln, or Hobart welder, the gas hose from your machine should screw right in, as they should use the 5/8" x 18 male portion. There are NO GASKETS or WASHERS to get the fittings to seal like other cheaper regulators sold that do not use the standard N-24 nut and NP-72 outlet.
The pressure gauge which shows how much gas is left in the tank goes from 0 to 4000 psi. This flowmeter does not use a diaphragm, so it is more reliable than the flow-gauge style regulators.
