* This CO2 gas mig regulator is designed for professional TIG/MIG welding applications.
* CGA-320 Connection for CO2 bottles.
* The output flow is adjustable from 0- to 25 lpm. And is indicated by a ball which moves up and down in the flow tube.
* The material of body is full copper. Great for Miller, Lincoln, Hobart, HTP, and most other welders!
* This flowmeter does not use a diaphragm, so it is more reliable than the flow-gauge style regulators.
