With solder wire perforation. A small blade perforates the solder wire down to the flux core while feeding it. This perforation process allows better flux flow and outgassing, avoiding solder and flux splashing during the soldering process.

It is compatible with solder wires with a diameter of 1.6 mm / 0.063 in.

This Guide Kit suits for the SFR Solder Feeder and is easily exchangeable if different solder wire diameters are used.

Guide Kits are also available without solder wire perforation and for other wire diameters.
