Yes, the Ironwood 650 is the cheapest model in the Traeger line-up to feature Super Smoke, the larger Ironwood 885, and the second-generation Ironwoods, and the first and second-generation Timberline models also all feature Super Smoke.

Super Smoke works between the temperature settings of 165 to 225 degrees. What it does is deliberately reduce the rate of pellet fuel into the burn pot so the pellets smolder for longer. It also comes with wider temperature swings as a result, so just be aware of that.

Super Smoke is essentially similar to features like the P-Setting on Pit Boss pellet grills/smokers and the smoke adjustment you get on Camp Chef and Weber who call their feature 'Smoke Boost'
