Desoldering iron for electronics rework with external solder reservoir. For horizontal handling similar to regular soldering irons. Electronic temperature control. Micro finger switch controls quick start, fast action vacuum pump. Different interchangeable nozzles plus several CSF heads are available. The DSX series tools feature a novel threadless desoldering nozzle fixture system whereby the nozzle is inserted into the head and locked into place by applying a 1/4 turn. This patented feature allows the desoldering nozzles to be quickly and easily exchanged and also improves the rate of thermal transfer from the desoldering head to the desoldering nozzle providing the tools with a faster heat up time and recovery rate. Additionally, because there are no threads in the head to foul, maintenance and costs are reduced.
