First off, I would always say your 3 basic cut quality factors are Speed, Height, and Amperage. By changing any of these 3 things, you will see a difference in your height. Second, 3/16" to 1/4" is probably too far off the material for this material at 40 amps, the 1/8" number to 3/16" sounds much more true.
The Red Screen AVHC box uses a potentiometer dial to adjust the Arc Voltage, if you can not set it lower than 100, a simple replacement should fix that problem. We sell the replacement at $30 for the exact replacement, or you can source one yourself. I believe it is a 10 turn 5,00 ohm potentiometer. If you remove the old one it should be tagged with the specifications.
