After feeding welding rod the rotation rates of motor will become heavier, if it
becomes very difficult, please stop immediately, may be the screw heating time is too
short or the temperature is not high enough. Or the temperature is so high that lead to
the cut solder particle has been melt and clinging to the cutting blade to cause the
plugging before it falls into the extrusion gun body. In this case, it is necessary to
remove the Y type extrusion gun body and clean the scrap on the cutting blade to
ensure that the equipment is not damaged normally.
6. Faster welding speed need to higher heating temp. At general condition, the hot air
temperature is between 260
℃
to 450
℃
. Choose suitable hot air temperature is
important during welding.
7. Adjusting the temperature and speed to make sure the welding rod is melting and
extruding perfectly when actual operation.
8. The operator needs to press the hand extruder on welding seam during operating,
to make sure the melting material can bond well on seam.
9. Flat welding shoe and 90-degree welding shoe suitable for different welding ways.
Pls rotate and pull out of the welding shoe or preferably with a little heat and remove
when you need to replace it, do not pull or knock directly.
10.
Finishing stage:
Extrude all welding rods which inside the cylinder (when the
motor voice getting lighter that means extrude completely), and clean out the welding
materials that on the air outlet. Otherwise it may cause blocked when you use next
time.
11.
Shutdown stage:
Adjust the hot air gun to cold wind and cooling the heating
element at least 5 minutes before shutdown.
12. It needs to clear out all previous welding rods before next time to starting the
hand extruder up.
13. The service life of carbon brush around 1600 hours, pls note that and replace it
timely.
