Welding Tips and Tricks

Just started welding and have learned a great deal from the videos on this site BUT I have one major question. I have a 2 gauge setup, one for tank pressure and the other show CFH. Decided to jump up to a flow meter and NOW it is calibrated in SCFH??? I've looked everywhere and can't find how to convert CFH to SCFH or are they just used the same way. In other words if I have been using 20CFH should I just set the flow meter to 20 SCFH? Totally confused

Yep, same animal, for all practical purposes. The "S" means "standard", and really shouldn't be used anymore. Unless you have a $5000 temperature, pressure, and humidity compensating flow-meter that can actually produce a standard cubic foot per hour.

thanks much, that clears it all up for me.
Great group!
