SxP-Solder Tip Cartridges are the standard soldering tip range for the Metcal MFR-1110, MFR-2210, and MFR-1351-series soldering systems. The second letter in the part number designates the temperature series. The SCP series is designated for high-temperature and thermally demanding applications up to 450°C. The Metcal "SmartHeat®-Technology" automatically adjusts power levels during each soldering operation.
