Question regarding this welder. I know its not the best and have struggled since day 1 with it. Got it mostly sorted out and working except for some reason the banner will stick to the lower belt upon exiting and start to bunch up. Not every time but more often then not. I have turned the heat down thinking it was too hot and sticking to the belt causing it. Maybe I didnt go low enough? Anyone have this happen and were you ever able to remedy it? Thanks in advance.
