I am in the process of looking for a regulator for a CO2 set-up. When searching for a regulator, what are some things to look for? I understand to look for two gauges, and know the difference betweem single and dual stage.
What else should I be looking for?
Also, many times I come across argon regulators or oxygen regulators; is the only difference the input adapter, or should I steer clear from them?
For example: would this work-- VICTOR MODEL AF-250 ARGON OR ARGON CO2 MIX REGULATOR
Make sure they have the cga 320 stem on the regulator or that will have to be changed. Other than that you seem to know what to look for. There is a big price difference between a single stage and dual stage regulator.
