Tips
The tip temperature will vary according to the shape of the tip. The preferred method of adjustment uses a tip
thermometer. (See “Calibrating the Iron Temperature” on page 3.)
A less accurate method involves adjusting the temperature control knob according to the adjustment value for each tip.
Example: When using a 900M-T-H tip at 400°C (750°F), the difference between this tip and
a 900M-T-B tip is -20°C (-36°F).
Set the temperature control knob to 420°C (786°F).
Refer to the chart for the correct adjustment values on page 15.
