Metal shell packaging with a durable metal wire core to help keep the work area clean and organized. Key benefits - Direct use at high temperature: no need to lower temperature or add water; maintains heat and preserves soldering quality. - Efficient heating contact: when the soldering iron tip is inserted into the metal wire, multiple contact points improve heat transfer and boost work efficiency. - Durable and gentle on tools: the wire is balanced for softness and rigidity, so it will not damage the soldering iron tip and offers a long service life. - Reliable construction: metal shell and wire design provide a sturdy, long-lasting solution for continuous use. Main features - Function: provides a stable, high-temperature interface for soldering work, helps maintain the working environment, and supports efficient operation. - Material: metal construction for durability and dependable performance. - Performance: designed to sustain high temperatures, deliver consistent heat transfer, and extend tip life. Applications - Electronics assembly and PCB soldering work where stable heat and clean workspace are needed. - Wire harness assembly and repair tasks that require reliable heat transfer and tip protection. - Field service and on-site maintenance requiring durable, long-lasting soldering support. Note: Use directly without water addition; does not require temperature reduction and is intended to preserve soldering performance.
