Soldering Tips

The Thermaltronics Curie point soldering irons, operate by using a high frequency RF wave delivered into an induction coil, which is wrapped around the soldering iron tip. This tip is made from a special alloy designed to have a specific curie point and the coil and tip are electromagnetically coupled just like the secondary of a transformer. The skin effect causes the high frequency current to remain in the outer surface of the soldering iron tip, rapidly heating it to the curie point of the tip. At this curie point, the tip loses its magnetic properties and the tip and coil are decoupled. With the tip and coil decoupled, power is no longer being delivered to the tip, and thus, it does not continue to heat up.
However, as you begin to solder with the iron, the temperature drops below the curie point of the tip, allowing the tip and coil to recouple and once again power is delivered to the tip causing it to heat to the curie point. This process is repeated very rapidly providing a very stable soldering temperature. The curie point of the soldering irons tip is effectively what sets the temperature. Since the tip loses its magnetic properties at this point, the heater can’t continue to heat the tip once the point has been reached/ exceeded. This produces an incredibly precise level of regulation that in theory means the soldering iron cannot overshoot the rating of the tip.

    M Series Tips are to be used with the Thermaltronics TMT-9000S-2 soldering system. M series tips can also be used in some Metcal
    Soldering Systems.  If you are using STTC tips from Metcal™ for your Metcal™  MX-500 series equipment, Thermaltronics M Series tips are compatible with these systems.

    M6 / STTC-6XX 325°C - 358°C Blue
    M7 / STTC-1XX 350°C - 398°C Yellow
    M75 / STTC-1XX 365°C - 410°C  Yellow
    M8 / STTC-8XX 420°C - 475°C Red
    Each Thermaltronics tip geometry will typically idle within a temperature range of +/-1.1°C. The length and geometry of a tip will have an influence on the tip idle temperature. 
    Example: A 2.5mm Chisel tips in the M7 series may be slightly hotter than 1.78mm chisel in the same M7 series. Rule of thumb is to use the biggest tip possible for the job to ensure the best results.
