Review on Upgrade Your Draft Beer Kegerator With The TerraBloom CO2 Keg Pressure Regulator - Dual Gauge Heavy Duty Unit With Safety Features by Andrew Mack

I was lately banging my head trying to find out what was causing extreme porosity in my TIG welds of mild steel. The vexing part of this problem is that it was intermittent. I could weld for a minute and make a good bead, then some porosity would start and destroy the weld. After troubleshooting nearly EVERYTHING involved, I replaced this reg with my old backup Miller dial regulator and the problem disappeared immediately. I really couldn't tell whether this reg was allowing atmosphere into the line or it was just starving the machine for argon, but either way, the results would be the same. Too late for a return.
