Plastic extrusion welding gun

1. Plug in the main power plug, install the handle, and place the welding machine on the shelf.
2. Pull the motor switch, the motor starts to rotate. If the new machine is noisy, it may be related to the vibration of the machine and the seat or the tightness of the parts inside the machine. If the motor is smooth and the internal sound disappears after feeding, it is normal.
3. After confirming that the temperature reaches the set temperature, pull the motor switch with the left hand to make it rotate, and immediately feed the welding rod to the inlet with the right hand, and the welding rod will automatically feed after feeding. At this point, pay attention to whether the material has started to discharge and whether the motor has become very difficult. When the material is empty, the motor speed is brisk, and it will become heavier after feeding. If it becomes very laborious, please stop immediately. It may be that the heating time of the screw is too short or the temperature is low.
4. Different welding methods require different welding nozzles.
5. It is necessary to press on the welder so that the welder can pressurize the weld. At the same time, the welding tip needs to be heated before starting to make the weld surface smoother. Of course, generally before the first 30-1500px, if the temperature of the welding tip is insufficient, the surface of the welding seam will appear unsmooth.
6. The welding speed, discharge, angle, and structure of the welding tip will determine the uniformity and appearance of the welding seam, but the most important point is that the temperature and air volume of the preheating hot air depend on the strength of the welding seam and the welding degree. Generally, The hot air temperature is 260-400℃. Of course, the faster the welding speed, the higher the temperature.
7. When the hot air moves with the welding machine, as long as the surface of the material to be welded can be blown by the hot air, it will become less glossy. The higher the temperature, the better the solderability is. It is very important to choose the correct temperature.
8. When replacing the poly-PTFE welding nozzle, please do not knock it hard, it is best to heat it to remove it.
9. The life of the carbon brushes of the hot air motor is about 1600 hours. Be careful to replace them in advance, and do not wait until the carbon brushes are used up.
10. Keep the preheating air filter clean.
11. When shutting down, the hot air temperature knob should be adjusted to the lowest first, and the hot air fan can be turned off after blowing for a few minutes.
12. When the machine is shut down, keep a little of the welding rod, so as not to damage the screw barrel when the extrusion screw is idling.
1 3. When the welding machine is turned on next time, the welding nozzle must be removed first, and the material must be cleared before turning on the machine.
