One of the companies I work for is Sellstrom. They have several welding helmets made here (280, 290, Advantage, etc.), though most of the filters are made in Switzerland.

They do carry fixed shade filters if that is really what you want, though I would recommend the MagSense, it is what I use and has patented dual sensors (optical and magnetic), so ambient light, other welding arcs nearby, etc., do not let it flicker.

I personally use the MagSense ADF in a Titan black/silver helmet.
Really not trying to plug one of the companies I work for... it's what I use and can speak to experience with it.
