Hello Brian in E Ore X 100!!! I figure that it sort of tells you something that Miller has been making that machine for eons now. Its a proven reliable machine. I welded with mine for 20 years before I bought a 251 wire machine. Only problem in all that time was to replace the on/off switch once. I'd take the Miller Dialarc dial rheostat over the Lincoln hand crank any day. That Lincoln hand crank seems like old technology, like cranking a Model T!!!
