Problem
No information is shown on the
display
The error message "H-E" is
displayed
The error message "SE" is
displayed
It takes a long time for the tempera-
ture to drop when you decrease the
temperature.
The solder is not liquid.
The preset temperature is not
correct
The temperature cannot be set
using the control buttons or the
temperature control dial
Smoke is emitted from the soldering
tip

Solution
• Is the soldering station connected to the mains and switched on?
• Has the fuse blown?
• The soldering station has detected an internal error in the heating
electronics ("H-E" = heater error). Switch the soldering station off, and
then switch it back on.
• Is the soldering iron connected to the soldering station correctly?
• The soldering iron may be faulty (cable, heating element or temperature
sensor).
• The soldering station has detected a problem with the soldering iron
("SE" = sensor error). Is the soldering iron connected to the soldering
station correctly?
• The soldering iron may be faulty (cable or temperature sensor).
• This is normal and does not indicate a fault. The heating element and
soldering tip take a while to cool down to the lower temperature setting.
• The temperature is too low.
• The heat from the soldering iron is dissipated too quickly (e.g. when
using larger work pieces). Set a higher temperature or use a soldering
tip with a larger/flatter tip.
• The soldering iron is not suitable (e.g. when soldering gutters).
• The soldering station is only designed for use with soft solders.
• When you use a measurement device to check the temperature of the
soldering tip, the measured temperature may differ slightly from the
preset temperature (the temperature sensor measures the tempera-
ture in the heating element; the measurement device measures the
temperature on the outside of the soldering tip).
• Calibrate the temperature in the settings menu.
• The soldering station was programmed to a fixed temperature (see
section 10. b). Refer to the instructions in section 10. c) to disable this
function.
• The flux in the solder wire evaporates during the soldering process.
This is normal and does not indicate a fault. Ensure that the workspace
is sufficiently ventilated and do not inhale the flux vapours.
