Mig gas pressure
I have been mig welding for about 20 years. I have my own fab. shop with several employees. One employee that I have had for 1 year is a great welder & great at fabrication. I have one problem whith him. He is determened to run 35 PSI gas pressure. Now unless I have a high draft, I usualy run 15 PSI or 15 to 20 on a flow meter & never have a problem. No matter how many threats I make, when my back is turned, he has the pressure turned back up. I feel that this is a waste. I can't find a good instruction manual for gas pressure settings. If I can't get it through his thick head about gas pressure settings real soon, I will have to fire him. Any solutions?

15 PSI is the absolute MINIMUM flow rate you should use on ANY project.
35 should be the max required without physical shielding. If he is good at what he does, he may feel the need to stick with what he knows for good shielding/penetration/ and quality. You are the boss, and he should be supbordinate to your requests. If all else fails, comprimise on 25, and lock-tite the adjustment knob!
Also, your welding supplier may have a handy dandy reference chart for regulator settings based on material and wire you are using.

Research a little here for guides and reference materials.
Btw PSI is not flowrate.
