UFT-Tweezer Tip Cartridges are the Ultrafine tweezer tip range for the Metcal CV-5200 and CV-500 series soldering systems. All cartridges are available in 2 temperature ranges, 600-series nominally 330 ˚C, 700-series nominally 390 ˚C. The temperature/series is designated by the first digit following the dash in the part number. e.g. 700-series will be UFT-7xxx. Metcal recommends the 700-series for the majority of applications. 600-series for temperature sensitive applications. Can be used with leaded and lead-free solder. The Metcal "SmartHeat®-Technology" automatically adjusts power levels during each soldering operation.
