When say "lighter", I'm only talking 1/8" material. I amusing the recommended settings for 3/16 material. Fwiw its a Miller 252.

Why not ?? Different gauges of metal are joined together every day. Generally the higher setting of the two is used with most of the heat aimed towards the heavier gauge.

We really would have to see the weld joint(s) to really know what the complainers are referring too. Sometimes, you can have a weld with decent fusion but if the weld is really tall it is considered "cold" as well. Causes range from slow torch travel speed, wire feed too excessive, not enough power etc... Perhaps strive to make the weld no more than 1/16" thicker than the material depending on the type of joint. That may mean beveling out the joint or creating a "gap" depending on the thickness and if your welder is not able to make the weld in a single pass.
