Hello,I am Aristidis from Greece.Below I adjust TIG welding to AR2 and I made test how to weld inox tube AISI 304 outside diameter 12.0mm thickness 1.5mm with end cap 9mm.It is accurate enough for production. The only problem is the backlash error. So I couldn't use circle command. When I try it it made an ellipse not a circle. Thank you for watching.
