TxP-Tweezer Tip Cartridges are the standard tweezer tip range for the Metcal MFR-series soldering systems. TFP-Tweezer tips are nominally 390 ˚C. Metcal recommends the TFP-series for most applications. The TCP Tweezer tips are nominally 450 ˚C and recommended for high temperature and thermally demanding applications. Can be used with leaded and lead-free solder. The Metcal "SmartHeat®-Technology" adjusts power levels automatically based on the demand of the application.
