Digital Display Soldering Station Intelligent Portable Welding Iron Kit with LCD Screen HK‑1000US Plug 110V Item Type: Digital Soldering Station Product Model: HK-1000 Display Type: LCD Power: 90W Temperature Setting Range: 150℃-480℃ / 302℉-896℉ Temperature Stability: ±2℃ (still air no load) Maximum Ambient Temperature: 40℃ Soldering Iron Tip to Ground Potential: <2MV Soldering Iron Tip to Ground Resistance: <2Ω Soldering Station Size(L x W x H): Approx. 120 x 160 x 100mm / 4.7 x 6.3 x 3.9in Install and Set up the Soldering Station: Use of Bracket and Sponge: Sponge is a squeezable object, and it swells up when wet. When using the sponge, wet the water first and then squeeze it dry, otherwise it will damage the welding tip. During the working process, if the sponge becomes dry, add water in an appropriate amount. 1. After taking the sponge out of the sealed bag, place the sponge in the groove of the base of the bracket. 2. Add a little water to the bracket, and the sponge will keep wet after absorbing the water. Temperature Setting: When setting the temperature of the soldering station, ensure that the temperature of the soldering station is in an adjustable state. The heating body (host) is not disconnected from the power supply during the temperature setting process. Welding Tip Use: Too high temperature will weaken the function of the soldering iron tip, so choose the lowest possible temperature. The temperature restoring force of this soldering iron tip is excellent, and it can be fully soldered at a lower temperature, which can protect temperature sensitive components. Tip Cleaning: Use a cleaning sponge to clean the tip of the soldering iron regularly. After soldering, the oxide derived from the residual flux of the soldering iron tip will damage the soldering iron tip, cause soldering errors, or reduce the thermal conductivity of the soldering iron tip. When the soldering iron is used continuously for a long time, the soldering iron tip should be disassembled once a week to remove oxides to prevent damage to the soldering iron tip and reduce the temperature. When not in Use: When the soldering iron is not in use, do not leave the soldering iron in a high temperature state for a long time, which will cause the flux on the soldering iron tip to convert oxides, which will greatly reduce the thermal conductivity of the soldering iron tip.
