　　The geomembrane welding machine is a very precise equipment, and its use must be operated by professionals. As the welding of the geomembrane welding machine is directly related to the speed and temperature setting during operation, it must be operated by a dedicated person. The following is the user manual for the geomembrane welding machine: 1. The user must select a three core power cord with a minimum of 10A and three sockets (corresponding to the welding machine plug, L-shaped live wire, N-connected neutral wire, and U-shaped grounding protection wire), and confirm that the external wire is connected properly. Check that the power switch is in the disconnected state, adjust the temperature control potentiometer and speed control potentiometer to the 0 position, press down the pressure rod handle of the geomembrane welding machine to separate the pressure wheel, and then plug in the power plug. 2. Turn on the power switch, select a certain temperature and speed, and take a few narrow pieces for trial welding. Due to differences in temperature and material thickness, the selection of welding temperature for the same material varies. Set the speed to about 2m/min (refer to Figure 3 for speed, adjust the potentiometer to the appropriate position according to the scale value), and slowly adjust the temperature from low to high (about 250 ℃ -350 ℃) to determine the best welding effect. 3. Judgment of welding temperature: For the correct PE material, it can be directly observed that the welding mark is flat and has a glassy appearance, indicating speed and temperature; Severe breakage of welding marks indicates high temperature or slow speed; If the welding mark is not white, it indicates that the temperature is too low or the speed is too fast. For non materials, observe whether there are obvious welding marks, or wait for them to cool completely before conducting tensile testing. 4. Trim the edges of the material to be welded straight, facing forward, overlapping the bottom left and top right, with a lap width of 100mm (or 150mm). 5. After determining the temperature and speed, place the material to be welded between the two pressure wheels, so that the body of the geomembrane welding machine is parallel to the edge of the base material, and close the pressure rod handle to self weld. In general, operators only need to observe whether there is any deviation between the welding mark and the edge of the base material, and make timely corrections within a small range. 6. When the material is welded to the end, promptly press down the handle of the pressure rod to keep the upper and lower pressure wheels in a separated state, in order to avoid burning out the rubber wheels for too long. 7. Due to thermal inertia, in welding, if the temperature is too high or too low, a small range of speed can be used to compensate for the temperature deviation. 8. The welded material is overlapped with another material in a "T" shape as six, and the weld mark on the side where the hot wedge is attached is diagonally cut to a length of about 100mm. 9. Adjustment of pressure. After using the geomembrane welding machine for a period of time, the pressure may decrease. If the pressure is too low during actual welding, as shown in Figure 7, use a cross screwdriver to pass through the hole behind the wire fixing bracket and align it with the M4 screw on the cam to the right, so that the more pressure, the more pressure (note that the pressure should be moderate and not adjusted too much at once to avoid damaging the pressure mechanism).
