Yihua 3pc service equipment set (Hot-air soldering station 993DM-IV + grotto station 939D+ IV + lab power supply 3005D-IV)Professional set of 3 equipment necessary for service, packed in one box, see below for detailed descriptions of each item.In the set:Yihua 993DM-IV soldering station with integrated flask on flexible cableBase with quick-change nozzle holderSet of 5 nozzles of different diametersGrounding wire for hot-airPower cord for hot-air stationGround soldering station 939D+ IVGround soldering iron 907JGround soldering iron holderMetal chip cleanerGround cleaning spongeLaboratory power supply Yihua 305D-.IV 30V 5APower supply wiresPower supply ground wirePower supply wirePower supply wireBox with holder for the whole set Yihua 993DM-IV Hot-Air Soldering StationProfessional hot-air soldering station with 1000W . Designed for professionals, the device has a precise temperature control in the range of 100-480°C with a closed-loop temperature sensor. The device is very powerful, so that heating time is reduced to a minimum, additionally equipped with an automatic cooling system that protects the heating element. Convenient easy-to-read display with the set temperature, and the current temperature, as well as the currently set airflow. The station with the ability to store 3 settings, thanks to the memory (channels - CH1,CH2,CH3) the machine remembers the temperature settings, and airflow. Powerful heater in causes rapid heating to the desired temperature. The station is equipped with a put-down sensor - if the hot air flask is put down on the holder, it automatically cools down to 100°C, after which it goes into standby (the heater is turned off). This is a solution that prolongs the life of the heating element. When the flask is removed from the holder it returns to its previous settings and heats up to the set temperature. Wide range of airflow control (use of brushless motor) Anti-electrostatic design (ESD Safe) High quality workmanship.Technical data:Temperature range: 100-480°CAir flow rate: 1-120 l/minTemperature display mode: digital LED displayWeight: 4.3kgPower rating: 1000WStation power supply: AC 220-240 V/50 HzDimensions of station: 200x164x156mm (L x W x H)Station power supply: AC 220-240 V/50 Hz Features:Hot air stationHot air flask automatically cools the heating element when the station is turned offStation made with ESD Safe technology1000W hot air soldering station with powerful heating elementLED display showing the temperature at the flask outletTemperature range from 100°C to 480°CSolid, very durable compact housingYihua 939D IV soldering iron stationSoldering iron station included with 907J flask with very high power of 60W, which allows you to heat the soldering iron to the desired temperature in a short time. It uses protection - ESD SAFE which protects it from overheating. Equipped with LED temperature display, which shows the temperature in real time. Universal soldering station for which a lot of interchangeable tips are available. One of the most reliable, proven models, super device for professional use. The station with temperature control from 200°C to 480°. The station has temperature stabilization, that is, maintaining the set temperature during soldering.
