It is a soldering iron with a ceramic heater. We can choose many tip shapes, we use it because the price range is cheap. Although the exchange frequency is high, the loss of the heater part is small. The soldering tip is susceptible to corrosion by soldering and the frequency of replacement is high.
I have used a few soldering irons up to now, but I feel that the feeling of grip is the best on my own. The price is also cheap, if it is made into an outlet, the temperature of the Nichrome heater can be reached to the temperature which can be used earlier compared to the cheap one. For professionals I think that there are also people who use more than tens of thousands of things that can adjust the temperature, but I feel full with Kore. I dare bought a thing with a high wattage. Recently, as lead-free solder increases in ROHS etc., the melting temperature gets higher, so it seems better for a thing with a slightly higher wattage. The tip is quite durable and I am using scallion like a marimo that weighed stainless steel (100 ha) to drop solder attached, but as of now, no deterioration is seen. I think that it can be recommended for both cost and manufacturer.
