about 20#. Since you only asked about the shielding gas pressure, that is what I initially reponded to. There are settings for both gas pressure and flow rate. These can vary depending upon the welding position, metal type/thickness, type of gas used, and conditions (wind, drafts etc.) My welding instructor told us that 20-20 is a good place to start (20 psi, 20cfm flow). I have produced good welds using Argon gas at about 25psi, and 22-24 cfm flow rate for welds in the flat position that are done in a welding booth (no wind). Every machine and welding setup/condition is somewhat different. It is usually a good idea to do some practice welds to find the best combination that works for that machine and setup. Make a note of what works, and stick with that for that setup. There is good info on online (Lincoln Electric, Miller, etc.). Hope this helps. Good luck!
