If the sensor, sensor area, or sensor cover is not clean, the unit may not detect coming and going of the tip and the brushes could keep rotating with non-stop. Please apply maintenance periodically according to the frequency of use.

Replace the sensor cover if it has cracked or there is a considerable amount of scratches on it. (Part No.A5062: Sensor cover for FT-720)

Please make sure to use the FT-720 always with the sensor cover. Otherwise, solder waste or debris may come into the sensor area and cause a malfunction of the unit.

You can make the opening wider by removing an adjuster.

When you want to clean a bigger soldering tip, it makes the work easy and efficient by doing so.

In case an extremely slim tip is applied, the sensor may not be able to react to tip coming and the brushes do not start rotating.

  The removed adjuster can be stored inside the base of the unit.

Other than the standard fluoroplastic brush, you can change to use the optional brushes.

Metal brushes	Fluoroplastic brushes	Resin Brushes
Effective in removing solder from a tip completely Recommended for soldering fine and precise components. Almost no solder remains on the tip after cleaning. Need to pay attention to tip oxidation.	Long-life brush with excellent durability The ideal amount of solder remains on the tip after cleaning. So, it's recommended for a wide variety of soldering, including high volume soldering operations.	Effective in reducing the impact of tip oxidation while soldering with lead-free alloy or halogen-free flux. A sufficient amount of solder remains on the tip to avoid oxidation. Instead, precise control of solder amounts isn't easy.

Guideline of solder amount left after tip cleaning

Solder waste and flux residue accumulate in the solder waste collector. Regularly remove and discard them as necessary.
