For lead-glass and Tiffany work, we recommend the temperature-controlled HAKKO FX-601. It has the necessary heat reserve for long solder joints on copper foil, lead rods, and large solder joints, and is generally more suitable for this application than a fine electronics soldering station. In practice, the wide 6.5-mm tips T19-D65 and T19-C65 are used almost exclusively for this purpose. Smaller T19 tips transfer too little heat to the wide joints, thereby unnecessarily prolonging the contact time. Which of the two tip shapes is more suitable depends on the seam path and your preferred working angle. Set the temperature only high enough for the solder to flow quickly and evenly. The appropriate setting should be determined using the solder and flux you are working with, along with a test piece.

The actual soldering tip temperature is measured directly at the wetted soldering surface using a suitable temperature measuring device such as the HAKKO FG-100B or FG-101B. First, allow the station, handpiece, and soldering tip to stabilize at the set temperature. Clean and re-tin the tip, place it gently—without applying excessive pressure—on the intact sensor, and add a small amount of solder to ensure good heat transfer. Repeat the measurement under stable conditions. Only reproducible deviations should be corrected and documented using the offset or calibration function, as described in the operating instructions.

Yes. HAKKO T39 soldering tips combine the heating element, temperature sensor, and tip into a single, thermally tightly coupled unit. This integrated design enables rapid temperature sensing and uniform heat transfer all the way to the soldering surface. As a result, the tip temperature can be regulated stably even under varying thermal loads. The T39 series also offers numerous geometries, including B, I, D, BC, and K shapes, as well as special variants. This allows the contact area and thermal mass to be selected to suit the pad, component, and accessibility. T39 tips are used with the standard FX-9701 handpiece; compatible variants are also available for the N2 FX-9702 handpiece.

It depends. Whether older HAKKO soldering tips are compatible with a new FX station depends on the station, the handpiece, and the tip family. The FX-951 and FX-952, when used with the FM-2028 handpiece, use tips from the T12 and T15 families, respectively. The FX-971 and FX-972, in their standard configuration, work with the FX-9701 handpiece and T39 tips. Therefore, even identical tip designations do not guarantee interchangeability. Always check the complete product codes for the station, handpiece, and soldering tip before ordering. For special handpieces or conversion kits, the specific combination must be approved.

The service life of a HAKKO soldering tip cannot be generally specified in operating hours. It depends on the soldering temperature, solder, flux, tip shape, application, cleaning, and idle time at high temperatures. Use the lowest temperature at which the solder joint forms quickly. Clean the tip gently and fully re-tin the soldering surface immediately afterward. During breaks, use the temperature reduction feature or automatic shut-off. Files, abrasives, and vigorous tapping damage the protective coating. The tip should be replaced if pitting, deformation, or consistently poor wetting occurs.

With the FX-972, handpieces FX-9701 through FX-9708 can be connected to either channel 1 or 2; there is no fixed assignment based on tool type. With the FX-973 as well, the FX-9701 through FX-9708, as well as the FR-4103 desoldering tool, can generally be used on any of the three connections. Restrictions apply only to the simultaneous operation of multiple high-power tools from the FX-9705 to FX-9708 series. In such combinations, one tool is set to standby mode. The channel selection can therefore be made based on the workflow and cable routing.

The FX-972 supports eight handpieces: FX-9701 through FX-9704 for standard, N2, and micro soldering, FX-9705 as SMD tweezers, the FX-9706 as micro-tweezers, and the high-performance soldering irons FX-9707 and FX-9708. Both ports can be freely assigned. However, two tools from the higher-power group (FX-9705 through FX-9708) cannot be active at the same time. The FX-973 supports the same eight handpieces as well as the FR-4103 desoldering tool. If multiple high-power tools are connected, one of them is placed in standby mode; lower-power combinations can be used simultaneously.
