Product Overview LST620 serial is a new type of granules hand extrusion welder which is based on the summary of ten years of industry application experience. This hand extrusion welder is the first type which applied with granules feeding barrel in domestic market. It has reached or exceeded the same type products of oversea, filling the domestic blank. The major components (hot air gun and drive motor) are made of imported brand-name accessories, stable performance, and long service life; there are two independent systems, one is for preheating raw material, the other is for heating granules. Reasonable structure, convenient operation, continuous welding, high working efficiency,

It is the ideal product for a variety of thermoplastic welding processing. This product is with two major components preheating raw materials hot air part and granules extrusion part - hot air part with adjustable temperature controller to heat automatically and extrusion part with independent thermostatic heating control system to send hot air independently. It is easy to adjust extrusion speed and use screw extruding for powerful extrusion pressure. Using 220v power supply uniformly to weld plastic sheets, tube and other thermoplastic products, especially for both ends of large diameter hollow wall pipe, producing pipe and repairing pipe and so on. Available welding materials: thermoplastic HDPE, PP, PVDF, especially PE. Do not apply in a conductive plastic (PE-EL), or cause the machine to produce a conductive short-circuit. Replacement of the different welding shoes can be applied for: 1) Plastic container’s welding, stitching, etc; 2) The large diameter plastic pipe’s welding, repairing, splicing, sealing, etc.; 3) The thicker plastic membranes, geo membrane splicing, patching and so on. 3.

Operation Steps: 1. Put the hand extruder on the shelf, install the handle, and plug in the mains plug. 2. Open the control box switch, welding temperature is generally set at 300 ° C-340° C, when the temperature is below 270 ° C, the motor switches off, you cannot start, when the temperature reaches 270 ° C, the motor switch is turned on, you can start properly. Open the hot air machine power switch, thermostat knob, heated a few minutes to operate. 3. The right hand pulls the motor switch, the motor starts to rotate. The new tool noise, probably it mostly is relevant to the resonance between the tool and the base or the close of the parts inside the tool. To check if the motor is very smooth, and the internal sound disappears after sending welding granules. 4. It is better to re-standby 5 to 6 minutes after ensuring the motor can be started. Then put welding granules into barrel to operate. Adjust the temperature carefully depending on the thermoplastic case. 5. Motor’s rotating speed is fast without granules and will become heavier when sending granules, if it becomes very hard to be operated, please stop it, probably because of short screw heating time or low temperature. 6. Different welding methods require different welding shoes; our company

Need pressure on machine then can be pressurized on the welding seam. Extruding some plastic material to heat nozzle, then make welding surface smooth. 8. Welding speed, extruding angle, nozzle structure will determine welding seam’s looking, but the most important thing is air temperature and air volume. It determines welding strength. Usually hot air temperature is 260 ~ 400 ℃.Certainly, the faster welding speed, the higher required temperature. 9. Hot air with the welder moves. It is alright as long as can make the surface to be welded after the hot air blowing. The higher temperature of the welding is not the better. Select the correct temperature is very important. 10. Please do not knock when replace the PTFE welding head. It is better to heat then take down.。 11. Hot air motor carbon brush life is about 800 hours, attention to early replacement; do not wait until the carbon brushes to run out. 12. When shutdown the machine, please switch hot air thermostat knob to the minimum, a few minutes blowing before they shut down the hot air machine. 13. Retain a little of welding granules when shutdown the machine to avoid extruder screw’s damage. 14. Clean up welding nozzle when shut down machine. 6. Product Features：  Imported hot air welding torch and imported driven system, high temperature, big torque, long service life, stable performance.  Feeding granules: cost-effective, without cutting process, low noise, extruding volume can be controlled 1-3.5kg/h.  Light weight, easy to handled and available to operation at different angles.  Double heating systems: granules feeding heating system and hot air heating system make sure the best welding quality.  Microcomputer chip controller makes easy operation and powerful protection function.  Extruding motor will shut down automatically if it has not reached the preset melting temperature, which avoids loss caused by operating mistakes.  The 360-degree rotating hot air welding nozzle can be applied to different needs.  Plastic granules feeding barrel makes extruding volume largely and being operated easily.  It is used in the tank and pipe and is comply with Part 4 of the DVS

And then switch back to operation temperature and start to do welding work after the current temperature reach setting temperature in 2 minutes. 3. After stop using or before using this machine, please make sure the welding nozzle is clean without plastic, otherwise, it will seize up melted material inside the machine, which cause materials back-flow and spray. Back-flow can damage the device, and spray can be the danger of burns. Hand extruder after use: knob the hot air blower temperature to zero point after use, cold airing 3-5 minutes to cool down completely, then turn the power off and keep them well. Clean the air inlet regularly to keep the filter clean, smooth into wind. 4. The device is turned on, there must be supervised, or may cause equipment damage and cause a fire hazard. 5. Our hand extruders possess motor cold start protection: when the temperature reaches below 270 ° C, the motor switches off to avoid of motor damage cause by disoperation；Metabo extruding motor has a tap positions . It has been set in “6” position properly. Any adjustment is not recommended, otherwise, it may cause improper use and motor damage which caused by large resistance.
