HAKKO 373・374 Optional Parts Combination Table

It is necessary to have optional parts compatible with solder feeding system HAKKO 373 or 374
according to the soldering iron and solder diameter used.

 

One-handed soldering

Feed solder wire with a tube unit and a guide pipe assembly.

We recommend a bottom feed type newly introduced, for better workability.

  • However, please use the conventional type when you want to solder with a special-shaped tip like a concave shape.

The HAKKO 373 and 374 do not accept lead-free solder 1.6 mm dia.

Lead-free solder, more rigid than usual Sn/Pb solder, does not go through smoothly due to greater friction resistance with the tube unit, and 1.6 mm dia. solder wire tends to be fed idly.

Required optional items
  • Solder diameter adjustment ring (for 373 only)
  • Tube unit
  • Guide pipe assembly
  • Iron receptacle (for bottom feed type only)
