Problem 2: The temperature of the SMD station is not rising.
Description:
Display lights up but the temperature of heat gun is relative low and
not heating up.
Solution: Heat gun cord or heating element may be damaged, please replace a
new heat gun.
Problem 3: Heat gun temperature is intermittent.
Description:

Display lights up but the heat gun temperature rises and falls uncontrollably.

The temperature is less than 50
℃
, and no longer heating up in working state.
Solution:

Heat gun plug may be loose from the receptacle, unplug the heat gun and
re-attach.

Heat gun cord or heating element may be damaged, please replace new heat
gun.
Problem 4: The temperature of soldering iron tip cannot be increased
Description:

The temperature display shows the temperature, but the temperature of the
soldering iron does not reach the set relative temperature or is not heated.

When the display temperature is less than 50
℃
and does not heat up again,
or when the temperature of the soldering iron tip rises intermittently.
Solution:

Is the soldering iron wire damaged? Please replace the soldering iron handle.

The heating core may be damaged, please replace it with a new one

Please refer to " Refer to checking for breakage in the heating element ".
Problem 5: The temperature of soldering iron tip or hot air is too low or too
high
Description: The temperature deviation between the temperature display and
the soldering tip is large
Solution:

Is the soldering iron tip aging seriously? Please replace or clean the soldering
head.

Is the calibration correct? Please recalibrate
Checking for breakage of the heating element and cord assembly
Disconnect the plug and measure the resistance value between the connecting
plug pins as follows.
If the values of 'a' and 'b' are outside the above value, replace the heating
element (sensor) and/or cord assembly .Refer to Procedures 1 and 2. If the value
of
“c” is over the above value, remove the oxidization film by lightly rubbing with
sand-paper or steel wool the points as shown.
