Then you want the 140 Plus. Personally, I like the clicky switches - those welders tend to be the ones you move around a lot on a big job and when moving them the dials often get bumped. I have the 175T instead of 175Plus for that reason.
One thing about the little Lincolns. The guns will bind up if you bend them in too tight an arc. Many wirefeeding problems with mine are resolved by straightening out the gun cable a little.
