ANBES Soldering Iron Kit design for various uses, from home DIY, electrical repairs jobs and other soldering project. upgrade version: ?adding an on/off switch, you can turn the soldering iron on or off. More safer and ease. ?8-in-1 precision pocket screwdriver, multiples tips for your solder, keep it inside the pocket. ?upgrade wire Cutter, you can cut and strip different size cable easily. Specification: work voltage: 110v work power: 60W temp Range: 200? - 450 ?(392? - 842?) soldering tips material: Pure copper Tweezer: esd-15, length 4. 7inches> soldering iron stand: steel> tips model: 900M Series> de soldering pump: plastic and aluminum alloys> solder wire: 60%sn-40%pb carry bag: PU Leather> package included: 1 x welding iron with on-off switch 2 x soldering iron tips> 1 x solder sucker 1 x anti-static tweezers> 1 x screwdriver> 1 x soldering iron stand 1 x wire Cutter> 2 x 22AWG electronic wire> 1 x solder wire> 1 x Test leader> 1 x PU carry bag warm tips: ?please switch to the 200? model When not using and please do not keep the soldering iron stay at high temperature all the time, which makes it easy for the iron core to accelerate oxidation and burn out, shortening its life. ?please melt a little solder wire on the tip of soldering iron after use, if there is black Oxide on the tip, the tip may not be tinned and must be cleaned Firstly. ?tighten the screws of the soldering iron table with pliers. ?try to use low temperature soldering. High temperatures will accelerate the oxidation of the tip. If the tip temperature exceeds 450 ° C, its oxidation rate is twice that of 380 ° C. ?when welding, do not apply too much pressure, otherwise the tip will be damaged. As long as the tip can fully contact the solder joint, heat can be transferred. In addition.
