Nice design, more reliable and practical. Using stainless steel solder pot, with a high temperature, acid, abrasion resistance, non-stick tin, tin oxide surface less so; Tin less, less power consumption, energy saving, long life Effective insulation technology to shorten the melting of tin time, improve thermal efficiency, reduce energy consumption Electronic thermostat circuit design, the working temperature from 200-450., Manufacturer: ZXZZAS
