Apex Tool Group FlowinSmart® Solder Feeder provides precise, one-handed soldering. FlowinSmart Solder Feeder features a nonstick coating inside the solder feed tube. The coating reduces the possibility of flux adhesion and reduces maintenance needs. Integrated start, stop, and standby functions conserve energy and the unit's service life. This Apex Tool Group solder feeder offers pulse and normal modes. Pulse mode applies a defined amount of solder each time the finger-activated switch is pressed. Normal mode continuously delivers solder wire when the finger-activated switch is pressed.
