                          A13:Installation notes include:<\/span><\/p>\n

                            \n
                          1. \n

                            This machine should be used in a <\/span>dry, indoor environment with minimal dust and no corrosive gases<\/span><\/strong>.<\/span><\/p>\n<\/li>\n

                          2. \n

                            The power supply for this machine must be equipped with an <\/span>air switch and a qualified grounding wire<\/span><\/strong> to ensure safety.<\/span><\/p>\n<\/li>\n

                          3. \n

                            Connection Between Machine and Electric Box<\/span><\/strong>: Position the main box beside the machine. Align the aluminum plate of the resonance tank inside the main box with the adjustment capacitor enclosure under the machine, then slide it in. Secure the adjustment capacitor enclosure to the resonance tank using the M4 self-tapping screws provided. Next, connect the copper strip on the base of the resonance tank to the machine’s support frame. Finally, fasten the conductive strip from the resonance tank onto the corresponding mounting holes of the middle aluminum plate of the machine’s adjustment capacitor. Ensure the conductive strip does not come into contact with the aluminum plates on either side.<\/span><\/p>\n<\/li>\n

                          4. \n

                            Electron Tube Installation<\/span><\/strong>: Open the top cover of the main box. Carefully place the electron tube into the center of the resonance tank. Adjust its orientation and secure it to the mounting base with screws. Connect the filament wires to the filament screws of the electron tube. When tightening the nuts, use two appropriate wrenches to hold the upper and lower nuts simultaneously. This prevents damage to the ceramic body of the electron tube, which could render it inoperable. Secure the grid copper strip to the grid of the electron tube with screws. Ensure it is tightly fastened without any looseness.<\/span><\/p>\n<\/li>\n

                          5. \n

                            Connecting Plugs and Installing Power Cables<\/span><\/strong>: Insert the control wire plug and spark wire plug from the middle of the machine’s support frame into the corresponding sockets on the main box, and secure them tightly. The machine uses a 5-core power cable. The yellow-green wire is for grounding, “N” connects to the neutral wire, and the remaining three wires (A, B, C) connect to the live wires (phase sequence does not matter). Ensure the power supply is connected to a three-phase 380VAC, 32-63A air switch. For personal safety, the grounding wire must be securely connected.<\/span><\/p>\n<\/li>\n

                          6. \n

                            Air Source Installation<\/span><\/strong>: Connect a suitable air source to the machine’s pneumatic filter using a 10mm plastic air pipe.<\/span><\/p>\n<\/li>\n<\/ol>\n<\/div>

                            Q14:What is the operating method of the HF-815?<\/span><\/span><\/strong><\/p>\n

                              Power on the machine<\/span><\/strong>. Turn on the power switch on the control box and the main power switch on the machine. You should hear the fan running inside. The power indicator (green) will light up, and the filament of the electron tube in the resonance tank will glow.<\/span><\/p>\n<\/li>\n

                            3. \n

                              Install the mold<\/span><\/strong>. Secure the mold onto the upper die heating base.<\/span><\/p>\n<\/li>\n

                            4. \n

                              Adjust the mold<\/span><\/strong>. Press the foot pedal with your right foot to lower the mold. Turn the handwheel above the machine head to adjust the spring pressure until it feels at the foot pedal is fully depressed. Lock the handwheel. Adjust the horizontal screws on the upper die frame to ensure the mold is parallel to the worktable. Tighten all adjustment screws after setting.<\/span><\/p>\n<\/li>\n

                            5. \n

                              Test the high-frequency output<\/span><\/strong>. Turn off the air (or hydraulic) switch. Step on the electric pedal without lowering the mold. The anode current should indicate around <\/span>0.2A<\/span><\/strong>. If arcing occurs in the resonance tank due to dust or debris from transportation\/installation, repeatedly step on the high-frequency switch to clear it.<\/span><\/p>\n<\/li>\n

                            6. \n

                              Set up welding parameters<\/span><\/strong>. Fix the insulation board on the worktable and place the workpiece. Lower the mold to align with the workpiece. Turn the tuner clockwise to set the pointer to zero. Set the welding time to <\/span>10 seconds<\/span><\/strong>. Step on the electric pedal to start welding. Slowly adjust the tuner to increase the current while observing the ammeter. Release the pedal once the workpiece is welded. Wait <\/span>1-2 seconds<\/span><\/strong> for cooling, then release the foot pedal to raise the mold. Inspect the welding result. Reset the welding time (typically <\/span>2-4 seconds<\/span><\/strong>) and adjust the current accordingly. After several test runs, turn on the air (or hydraulic) switch for normal production.<\/span><\/p>\n<\/li>\n

                            7. \n

                              Mold preheating (optional)<\/span><\/strong>. The upper die base has a heating element and thermostat. Set the desired temperature according to the material (e.g., <\/span>120\u2103 for PVC<\/span><\/strong>, <\/span>80\u2103 for PET<\/span><\/strong>). Wait for the thermostat indicator to turn off before starting production. Preheating improves efficiency.<\/span><\/p>\n<\/li>\n
