Thermco's 6305 gas mixer produces gas at 0 to 10,000 cf/hr at standard conditions. The 6305 mixes CO2/Ar or O2/Ar for welding shield gas. A built-in gas analyzer continuously measures the gas mixture as it is mixed. The mixer incorporates a 120-gallon surge tank that maintains a precise mixture down to a 0 mixed gas-flow rate. Solid-state digital pressure switches control tank pressure. Normal pressure conditions are 120 to 145 psig and mixed gas outlet of 10 to 50 psig.
