CxV-Solder Blades are part of the rework soldering tips for the Metcal PS-900/MFR-1120, MFR-2220-series soldering systems. The second letter of the part number designates the temperature series. The CFV temperature series is nominally 390 ˚C. Metcal recommends the CFV temperature series for most applications. However, there is a higher temperature range designated CCV, nominally 450 ˚C, for high temperature and thermally demanding applications. Can be used with leaded and lead-free solder. The Metcal "SmartHeat® Technology" automatically adjusts power levels during each soldering operation.
