Adjustable solder furnace for metal casting with 400W capacityFeatures: -100% new and high quality -Using high quality 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 -With a small ladle is the liquid metal into the moulds in easily -Effective insulation technology to shorten the melting of tin time, improve thermal efficiency, reduce energy consumption -Easy to use, thermal effects, tin melting fast Please note: When working with liquid metal safety regulations (sicherheitshandschuhe, goggles, respirator) The temperature of melted solder shouldn't be too high, or it will cause the aging of solder pot, the darkening or yellowing of melted solder. When highly acidic scaling powder is applied, the solder pot is more likely to be corroded or perforated under extraordinarily high temperature.
