c. Choosing the Correct Temperature Series
Each cartridge is specially designed for high power delivery, which means that you can often solder
with a Metcal cartridge at a temperature 100°F (40°C) or more lower than with a conventional
soldering iron. Since Metcal tip cartridges sense thermal loads and respond to them, you need only
approximate the size of the loads you will be working with. Start with a lower temperature, going to a
higher temperature only when necessary.
