The pros for the ADS200 vs other Pace stations are:
1. Calibration is not required when changing tips. The WJS100 and MBT will detect tip removal and indicate that you need to perform calibration (by changing its LED from green to amber).
2. Availability of both compact Standard blue cartridges (1130- series), and high heat capacity Ultra Performance blue cartridges (1131- series), both able to heat at 120 watts.
The WJS100 is only compatible with the High Power gold cartridges (1128- series), a smaller selection.
The other Intelliheat stations are compatible with the Standard (1124- series) and long-life Diamond coated (1126- series) black cartridges, which is the largest selection.
3. more attractive price
Cons:
1. Unlike the Intelliheat ST, MBT, and WJS100 stations, the ADS200 can (currently) only be used with the TD200 soldering iron handpiece. In particular, it is not compatible with any of the Pace tweezer tools like the MT-100, which the WJS100 is able to use. The MBT stations with vacuum and hot-air support can use the widest range of tools, including older SensaTemp tools with a cable adapter.
The other tools you can use with a ST or MBT are:
TD100 cartridge soldering iron
PS90 tip soldering iron
MT100 mini tweezer
TT65 ThermoTweez large tweezer for large SMD components
TP100 ThermoPik tweezer with vacuum pickup
TP65 ThermoPik large tweezer with vacuum pickup
TJ85 ThermoJet air pencil
TJ70 ThermoJet large air pencil
SX100 SodrXTractor desoldering tool
