hi
i have 2 mig welders and have been welding mild steel with co2 gas drinks cylinders which i get refilled at the local fire extinguisher dealer for a very reasonable price .I get on ok with co2 but i sometimes need to get a better weld and penetration and since boc (argon shield ) is not an option due to rip off prices and nor is disposable bottles ,can i successfully & safely use my existing co2 gas cylinder ,T off to a pure argon larger off the shelf cylinder with its own smaller regulator and manually combine these two gases.
