Is the circuit connection of the 380V butt welding machine correct, how can it be determined? Recently, a customer inquired about our WP630A butt welding machine, where the heating plate temperature stops rising after reaching 180°C. What could be the reason? In such a situation, the first step is to check if the circuit connection is proper. The following video demonstrates the use of a clamp ammeter for this purpose. Note: If you are unfamiliar with circuits and current measurement, please consult us. Our company has professional electricians and technical personnel who can provide guidance.

Butt welding machines are suitable for most thermoplastic materials, which soften when heated and solidify when cooled.  The following are commonly used types of plastics suitable for hot melt welding:Polyethylene (PE): Polyethylene is a common thermoplastic material used extensively in the manufacturing of plastic bags, bottles, containers, and pipes. Polypropylene (PP): Polypropylene is another widely used thermoplastic material suitable for automotive components, electronic devices, medical instruments, and more. Polyvinyl Chloride (PVC): PVC exhibits excellent chemical resistance and heat resistance, making it applicable in construction, wire and cable, pipe manufacturing, and other industries. Polystyrene (PS): Polystyrene is commonly used in packaging, insulation cups, household appliance casings, and other manufacturing applications. Polycarbonate (PC): Polycarbonate offers outstanding impact resistance and transparency, making it popular in the electronics, optical, and medical fields.   Which plastics are not suitable for hot melt welding? Butt fusion welding is not suitable for thermosetting plastics, as these materials undergo irreversible curing after being heated and cannot be softened again. Common examples of thermosetting plastics include epoxy resins, phenolic resins, and unsaturated polyesters. Since thermosetting plastics cannot be re-softened, they cannot be joined using the hot melt welding method.

The professional construction team will make use of steel flanges to assist.The steel flange plate is used as a tool to hold and align short pipes and pipe fitting during the hot melt butt welding process. Its function is to provide a stable and secure connection during hot fusion butt welding of pipes, ensuring they are properly aligned and held in place during welding.This helps to prevent any misalignment or movement of the pipe, which could result in a less-than-robust weld. or even a failure of the hot fusion butt welder.The advantages of using a steel flange plate include its durability and strength, which allows it to withstand the high temperatures and pressures involved in the welding process. Very easy to use, with screw locking for quick and easy installation and removal. Additionally, the flange plate can be reused multiple times, making it a cost-effective solution for welding short pipes and pipe fitting.

When using a generator, the power recommended by Welping is 2 times as that of the pipe fusion machine. The machine's power is displayed on the specification label on the top of hydraulic station.For example, if the hydraulic station power is 10KW, the heating tool power is 1.5KW,and the planing tool is 1KW, then you need 25KW power for generator at least
