The Weller WMRP (T0052917199) Micro Soldering Iron (55W Max, 12V) is ideal for soldering under a microscope and other detail applications. The WMRP features excellent reaction time with fine tips and provides the fastest heat up and recovery on the market. The cartridge style tip can be easily and quickly changed without any tools required. Weighing only 2.65 oz (75 g), the WMRP is made from aluminum with chrome plating. The micro soldering iron is compatible with WD1M / WD2M series soldering stations and WR3M / WR3ME series rework stations. When placed in the WSR 205 safety rest (sold separately), the WMRP will power down, helping to extend tip life.
