1. During operation, first adjust the heater power to the lowest gear, and then gradually increase it according to the welding needs to reach the ideal temperature required for welding.
2. Before stopping the machine, the knob should be pointed to 0°C, and the air should be blown for a few minutes. When the barrel is cooled, the machine can be turned off, so as not to burn the spare heat.
3, the hand should touch the barrel of the gun when operating, so as not to burn. After use, you should put it gently, so as not to damage the parts in the gun and affect the service life.
4. Wear different nozzles and make potentiometer knob arrows point to different scales, and the temperature at 10mm from the nozzle should meet the requirements.
5, before the use of ventilation, in the power supply.
6. At the end, be sure to turn off the electric heating power first to let the barrel cool.
7, there are three levels of temperature control, inside two has been controlled, the last level let it adjust the temperature of 60 degrees, the knob to 10 o 'clock position.
8, when the crack or fine crack through the space narrow, so that we can use the pendulum welding method.
9. Prepare the electrode in the normal way by putting the electrode into the "V" shaped groove by hand and placing it between 80 and 90 degrees of the groove. When the hot air is running to heat the tool, apply 0.025MPa downward pressure to the electrode and perform continuous pendulum welding towards the bottom. The amount of pressure used during operation is determined by the relative thickness of the component materials used in the electrode.
Precautions for the use of plastic welding gun
1. The handle switch is divided into three gears: I switch on the electric heating wire; Second grade starting motor air supply; Stop third gear. When used, the starting motor should be supplied with air, and then the electric heating wire should be energized. When the electric heating wire is stopped, the power supply should be cut off first, and then the wind should be stopped slightly, which can avoid excessive residual heat of the electric heating wire, shorten the life of the gun core or burn the lead wire.
2. In the process of use, if the temperature is too high, it can be retreated to file Ⅱ, that is, cut off the electric heating wire power supply, weld with waste heat, and then play file Ⅰ when appropriate, so as to ensure the service life of the long gun core and ensure the welding quality.
3. When used for the first time, there may be fire or smoke. This is a normal phenomenon, power-on about 5 minutes will automatically disappear.
4. When the switch is placed in gear Ⅰ, there is mild temperature in the outlet, which is a normal phenomenon.
5, plastic plate is heated to 130℃ ~ 140℃ when it becomes soft, a little pressure can be formed. The welding temperature is generally about 240℃, and the temperature of about 5 ~ 10 mm from the welding nozzle mouth is 200℃ ~ 260℃. When welding, attention should be paid to the distance between the nozzle and the welding spot, so as to obtain the ideal welding temperature.
6. After the electric heating wire is broken, you can screw the connecting screw of the firing shell, take out the gun core, and wrap it evenly with 300W electric heating wire to still be used. The damaged core can be purchased by letter from our factory.
7, the torch should be put gently after use, so as not to break the fireproof porcelain part of the gun core, and make the heating wire short circuit.
8, for use, must be connected to the ground wire, to ensure safety.
9. If the power cord is damaged, it must be replaced by the manufacturer or its maintenance department or similar full-time personnel in order to avoid danger.
10. This appliance may cause fire if not used carefully.
11. Be careful when using this appliance in places with flammable materials. Do not use this appliance in the same place for a long time.
12. Do not use this appliance in an explosive environment.
13. Heat may be transferred to flammable materials at a distance.
14, after use, put the appliance on the support to cool it, and then save.
15. Be sure to take care of this appliance when using.
