Preset Channel
You can save up to three sets of temperature and air volume settings into the three preset channels, so you don't have to constantly adjust temperature and air volume settings for works that are different in temperature requirement.
How it works: You can set Channel 1 to 662°F (350°C) for component A, Channel 2 to 716°F (380°C) for component B, Channel 3 to 212°F (100°C) for heat shrinking. While you're working, you can switch between these settings with just ONE press of a button.
