On wire size, 1/4" steel and up, I use .045 most of the time.
Then use .035 on the thinner metal.
I did get the .030 feed rollers for the 255 and have a roll of .030 wire, but have not try it yet.
Running way behind this fall, I have app 50 signs that should of been mailed out last week and I still do not have them powder coated.
Got to weld up fire pits today, 15 will be pickup tomorrow. So, I will see if I can learn anything else about the setting on my 255.
