Everlast machines balance controls are % EP so you need to change the percentage you would use from Miller or Lincoln. So 65% EN = 35% EP. It's just a brand difference, one of those things that you have to learn about your particular machine. Like because Everlast uses metric flowmeters you will use liters per minute instead of cubic feet per hour. You will often run into information in the US that talks about CFH and European info that talks LPM. At least for that one, the conversion is pretty easy. Double LPM to get approximate CFH, or cut CFH in half to get approximate LPM.

Sounds like you are getting there, it just takes practice. Yes, you can go over a bead a second time to help even things out and add filler for just the places that need a little more. One thing about aluminum though, if you get the workpiece too hot, things will go bad in a hurry. So if you are welding something over and over, you might need to stop and let it cool down some before welding more on it. Aluminum is sensitive to heat if it's too cold it's hard to weld, and if it's too hot it is too. There is a sweet spot where it's just great. I think it's about 200 - 300°F where everything just works.
