The JBC Tools SF-110VB Automatic Solder Feeder allows you to feed solder wire automatically from any position and can be easily configure with parameters such as dispensed wire speeds and length. It has three working modes (continuous, discontinuous, and program) and each program can configure up to 3 steps with different dispensed wire length and speed. Up to 35 programs can be executed, cyclically programmable. The JBC Tools SF-110VB Automatic Solder Feeder has a solder feeder that features a small blade that perforates the solder wire down to the flux core while feeding it. This process allows for a better flux flow and outgassing and voids solder and flux splashing when soldering.
