Ok,I think I see the problem. It's either something minor,something major or it might be a combonation. Let's eliminate as many things as possible then concentrate only on what's left. You mentioned having good relations with one or more good welders. Why don't you ask one of them to weld something with your machine? If they can't do well,they will help figure out if the problem is caused by wire,gas or the machine. If and when they can run good beads,you try it with same settings to see what the result is. If you are still unable to lay good beads,at least you know it isn't the machine or consumiables. Leave the settings or at least write them down. Pratice on same material with same settings until you get the hang of it. You mentioned inability to see,have you had an eye test recently? Narrow it down so you know what you need and your frusteration level should lessen.
Now that sounds like a man that has solved a problem or two in his lifetime..
