minimum polebarn size

I have a 110 Miller welder does up to 1/8 if you dont push it. My 110 compressor is small but duty cycles enough for all my air tools. My 4 post lift runs on 110. It can be done. My pole barn is 40x70 and I heat it with 2- 450 torpedo heaters. 1 brings it to 55 degrees no matter how cold outside. I'm just across the state from you. BTW my lift is the wide 4 post Bendpak and its movable. Did the 8 inch floor with rerod so I could service semi's if I want to.
