The Metcal CV-UK6 Upgrade Kit includes the CV-H6-HTD High Thermal Demand Hand-Piece and a work stand. The kit transforms the CV-5200 Soldering System into a powerhouse. The High Thermal Demand Hand-Piece provides a boost in performance by more effectively delivering thermal energy to the most demanding loads. SmartHeat technology lowers the risk of overshooting delicate components. The very fast heat-up speed allows the user to continue to the next task even faster, while the ergonomic lightweight construction keeps the user comfortable even on large industrial jobs. The hand-piece is compatible with HCV cartridges in 700, 800, and 900 series temperatures (sold separately).
