Reliable digital technology by HAKKO – Introducing the HAKKO FX-888D Excellent thermal recovery Heater output has been increased by 30% compared to that of the conventional models HAKKO 936·937. Also FX-888D delivers excellent thermal recovery by using T18 series tips for their terrific heat conductivity. This allows soldering at a lower set temperature and reducing the thermal impact on components as well as tip oxidation that can shorten tip life. Thermal recovery graph Rise time to 350Degree C is 20 seconds faster and tip temperature drop is reduced during continuous work.
