Hobart once made a kit with a fixed regulatorflowmeter designed for Hobart mig welders but it could be made to work on most any 115 volt mig that is made to use with shielding gas. This bottle comes filled with 75 Ar25 CO2 mix making it a viable option for MIG processes and mild steel welding. A CGA-320 to CGA-580 adapter allows mounting a welding regulator on a CO2 tank. The SIP 390g CO2 Gas Bottle is a quality disposable pressurised mild steel bottle suitable for top welding performance in all environments.
