thewelderson,
WELCOME TO THE AWS FORUM!!! Hope you enjoy the info and opportunities available here.
A lot of companies are now selling 'pressure' gauges instead of flow meters for regulating gas shielding. They work fine for the average Joe in his garage doing hobby work. They are cheaper supposedly, especially than 'GOOD' flow meters.
But, for code work you will find things listed according to flow. The perameters should be checked according to the WPS you are working to, the manufacturer's recommended practices, and any code restrictions.
The previous poster is right in there on the average recommended flow rate. It can be up or down 'slightly' for some variables.
There is a ratio relationship between the pressure and flow, I just don't remember it currently. Seems as though 15 psi is about where you would want to be if you are working with pressure regulators. (Lord save me from these guys if my mind is taking a senior moment).
Interesting, where did the end of my post go? I know I had typed more than that. Can't even remember what it was now but I know I had my exit greeting there, SO-
Have a Great Day, Brent
Thanks to all for the welcome.
I do have a flow meter, so I do stand corrected in that I'm looking for the flow setting, not pressure. Some old welding books my father has does confirm 30cfh, but it just seemed a bit high for indoor welding.
Thanks-Lou
