Default argon / C02 regulators

My little 110v MIG welder that we use on job sites occasionally has a busted regulator / gage setup.

Is there a difference in the regulators / gages for the following

100% argon

75% argon 25% c02

100% c02



thanks
Mark

Yes there are differences; the gas affects the calibration, low cost flow meters are calibrated for one gas. More expensive gauges can have calibrations for 2 or more gases.

Big differences in quality of the gauges also. My Hobart came with plastic cased gauges on the reg.. One of them cracked, so I replaced both with brass cased ones. Much better.
