The arizer's temperature display is not really accurate so that probably isn't the temperature you're really vaping at, considering that is 500f, and you would be smoking if it were the true temperature.
What you should do is lower the temperature to around 210c, inhale VERY SLOW for 10 seconds or longer until your lungs are full, and that should give you better results.
Thanks for the heads up I will try that, and also check it with a pyrometer
Peace
