3. Connect the vacuum tube to the Smoke Absorber Terminal or
Vacuum Cap ("6" from the control panel). If smoke absorber
function is to be used.
4. Activate the "SOLDER IRON" Activation switch ("9" from control
panel). This will automatically start to increase the temperature of
the desoldering gun to 350°C (default).
6. Adjust the desoldering gun temp. using the SOLDER/DESOLDER
TEMPERATURE ADJUSTMENT buttons ("4" from the control panel).
7. Allow the desoldering gun's tip and its barrel to heat up.
temperature can be reached within 5-6 minutes and its barrel would
obtain optimum temperature 5-9 minutes after the tip temperature
has been reached. If upon initial use solder gets stuck at the end of
the barrel, clean the barrel and wait a few more minutes for the
barrel to heat up.
8. Check the tip temperature with an external temperature sensor,
adjust temperature settings higher or lower for the right
temperature. Or recalibrate at the desired temperature level
9. Ensure that all the solder is melted before triggering the pump.
(Partially melted solder will still be sucked up however it would clog
the barrel).
10. Upon pressing the pump trigger hold the trigger for 1 to 2
seconds longer, as larger lumps of solder may need a longer suction
time to clear the barrel and go into the filter.
11. Clean the filter and dampen the sponge frequently during and after
usage to allow better suction power.
12. When the task is finished, deactivate the SOLDER IRON switch.
Allow the desoldering gun to cool down before handling for storage.
Notes:
Please follow the procedures and tips presented above for more
●
efficient usage of the desoldering gun.
Industry recommended tip temperature for soldering is 600 to
●
610F (315 to 320C) for standard solders and 650 to 700F (340 to
370) for unleaded solders
