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.
Electrical performance
1. Power consumption: under 220V voltage, electric heating wire power + motor power ≤330W.
2. Insulation performance: adding 1250V AC voltage (50Hz) between "gun core", "motor" and "gun case" for one minute, no breakdown phenomenon
3. When the temperature is 20℃, the handle temperature shall not be higher than 30℃ after continuous use for 4 hours.
