Precautions and Troubleshooting for Operating Pipe Fitting Hot Melt Welding Machine

New or long-term unused pipe fitting heat fusion welding machines often have a large drop in insulation resistance between windings and between windings and casings due to moisture, and short circuits and grounding are prone to occur when they are first used, causing equipment and personal accidents. Therefore, use a shaker to check whether the insulation resistance is qualified before use.
Before starting the hot-melt welding machine for new pipe fittings, you should check whether the contactor part of the electrical system is in good condition. After you think it is normal, you can start a trial run under no-load. Only when it is proved that there are no electrical hidden dangers can it be put into trial operation under load and put into normal operation. If there is a problem with the pipe fittings hot-melt welding machine, first look at the problem of connecting the machine. If it is connected to the power supply and does not turn on, it means that the fuse is burnt out or the power interface is faulty.
After power on, the display screen does not display, the screen is blurred, and the machine buzzes. It may be that the display screen is damaged. The reason for the damage to the display screen is exposure to sunlight, heat, impact, aging, and wiring falling off. This problem occurs on the pipe fittings hot-melt welding machine. Rewire and replace display.
The current of the pipe fitting hot-melt welding machine cannot rise because the external power supply is undervoltage and the power cord is too long. It is necessary to check the external power connection and re-lay it. The reason why the power cannot be normally operated according to the set parameters is that the current parameter setting of the first stage is too low. The method is to increase the current parameter of the first stage, and the time is less than 30s, and then continue to weld with normal parameters.
