Well my new toy finally arrived and i thought i share my thoughts about it with you all
The model in question is the Thermaltronics TMT-9000s. Its quite a different setup from your conventional soldering iron / station in that there are no adjustments for temperature, it is all controlled internally based on the thermal load demands within the tips temperature range instead of having to dial up your temperature to try and compensate for extra loads.
blue band = 6 (600°F Type 325°C - 358°C) yellow band = 7 (700°F Type 350°C - 398°C) red band = 8 (800°F Type 420°C - 475°C)
The main power supply - This unit is a beast, enclosure is entirely metal with heatsinking integrated into the chassis and weights around 2kg, the front incorporates a 2 row LCD display to display the status of the unit, current thermal load etc. The unit features 2 switched outputs for multiple configurations.
The iron - The design is quite different compared to my old Hakko station with the hand-grip being biased closer to the tip, the silicone wire to the power supply is very supple and a very nice length also. Tip changing is a breeze with no locking ring and an included pad on the wire for changing hot tips on the fly, the tips simply slide in and out of the barrel and secure at the base, the connection is solid and reassuring with a very narrow barrel for good visibility.
The base stand - The stand is not metal like the power supply body but a "phenolic material" impressions are that it is some sort of very dense composite. Seating the iron in the stand is very secure and very little movement to speak of, it also features magnets around the neck of the iron to put it into standby state seems to keep it floating while seated.
Operation - The operation of this unit is where it really shines, from turn on the tip is at temperature in 5 seconds, the LCD display constantly feeds back about the status of thermal loading. I tested the unit out with some light SMD work and some big through hole jobs and it was an excellent performer. On the bigger jobs i attempted some 1" wide copper tracks and the iron was able to heat the track quicker than it could be pulled away allowing me to flow solder in under 3 seconds. My old Hakko took over 15 seconds and heated the rails considerably. SMD jobs were easy work for it also removing some RF shielding in seconds.
During operation you can see the response of the unit by placing the tip on a trace and watching the load increase on the LCD almost instantly to compensate. Also when the iron is seated in the stand, it will go into a standby state and ramp up to ready state again once it is lifted from the stand. This used to be a problem with slower irons but with its response time its never really an issue.
I would love to open to see what makes it tick but unfortunately this is my own unit and i would like to keep the warranty
On the topic of warranties, the unit is backed by a 4yr warranty for the power supply and 90 days on the hand-piece and stand.
