When purchasing welding equipment, many users often focus solely on the price and basic functions of the equipment, neglecting other key indicators. This may lead to the purchased equipment being unable to meet practical needs and even causing various problems during use. To avoid these pitfalls, we need to gain a deep understanding of all aspects of welding equipment to ensure that the purchased equipment can efficiently and stably complete welding tasks.

When equipment suddenly stops working, it often disrupts the normal workflow, causing unnecessary delays and losses. In such cases, it is crucial to quickly and accurately identify the cause of the fault and carry out repairs. Common causes of faults can generally be categorized into several aspects: power supply issues, electrical connection faults, mechanical component damage, and control system failures.

Workpiece deformation is a common issue in the spot - welding process. This is mainly due to the heat generated during welding, which causes localized temperature increases in the workpiece and leads to uneven material contraction. Additionally, factors such as excessive welding current, prolonged welding time, and insecure workpiece clamping can exacerbate the degree of deformation. If this problem is not effectively resolved, it will not only affect the appearance quality of the workpiece but also lead to a decrease in welding strength, thereby affecting the overall performance of the product.

Pneumatic spot welders use compressed air to drive the welding head for the welding operation. They offer advantages such as fast welding speed, stable pressure, and easy operation. These welders can achieve precise welding control and are suitable for applications where high welding quality and efficiency are required. Foot - pedal spot welders, on the other hand, control the welding process with a foot - pedal switch. They are flexible to operate and convenient for single - hand operation, making them suitable for scenarios that require frequent movement or handheld welding.

The PDKJ team customized and delivered the DB-170W platform type medium frequency inverter seamless spot welding machine (dual gun) based on in-depth research and customer core requirements for "seamless welding+efficient production conversion+stable accuracy", injecting new energy into the production line of customers in the Shenzhen intelligent communication equipment industry.

On October 24, 2025, the 6th Smart Manufacturing Summit for Photovoltaic, Energy Storage, Power Supply, Inductor, and Transformer (East China) will kick off at the Phase II of the Tongli Lake Resort in Suzhou! This industry event will bring together top experts, leading enterprise executives, and technical pioneers in the fields of photovoltaic, energy storage power supply, and inductor transformer, integrating industry resources in one stop to explore new directions for industry development! As one of the participating companies, PDKJ will showcase its core technologies and products in the welding equipment field, engage in in-depth exchanges and cooperation with the industry, and jointly explore development opportunities.

Copper, with its excellent electrical and thermal conductivity as well as corrosion resistance, is widely used in electronics, power, refrigeration and other fields. However, in actual production, copper welding often poses a headache for operators - - weld points are prone to virtual connections, porosity, and even failure to weld through.

Welding plastic and metal is challenging, but high - quality connections can be achieved with specialized equipment. Ordinary equipment cannot meet the needs.

For companies specializing in new energy equipment and accessories, the quality of welding processes directly affects product reputation and market acceptance. A Suzhou-based new energy client, with years of experience in the energy storage and photovoltaic fields, recently introduced PDKJ’s “platform-type medium-frequency inverter spot welding machine” to address welding challenges in metal components, thereby embarking on a new phase of efficient welding.

Hardware accessories such as hinges, fasteners, and connectors, when produced in batches, have their welding efficiency directly affecting production capacity. Many manufacturers, although using spot welders, often find themselves in the dilemma of "production capacity failing to keep up with orders" due to improper model selection or lack of automation configuration. In fact, scientific model selection and automation retrofitting can significantly improve welding efficiency.

Stainless steel kitchenware, such as pots, sinks, and knives, has extremely high requirements for welding appearance, with "seamless" being the core demand. When choosing welding equipment, small and medium - sized manufacturers often hesitate between laser welders and traditional spot welders. In fact, both have their own characteristics and need to be comprehensively judged in combination with the seamless demand, production scale, and cost.

How Laser Welding WorksLaser welding utilizes concentrated heat to melt and fuse materials at the joint:Process: The laser beam delivers intense, focused energy to a small area, creating a molten pool that solidifies into a strong bondKeyhole Effect: At sufficient power levels, the beam vaporizes ma

On the morning of October 13th, the conference room of PDKJ was filled with warmth and laughter — a special October birthday celebration for PDKJ employees began in this cozy atmosphere. All the employees of the factory gathered together to extend their most sincere wishes to the four birthday celebrants. Amidst the busy production and research, they shared the happiness of the PDKJ family.

The welding of automotive parts requires extremely high precision and efficiency. For example, deviations of even 0.1 millimeter in weld points on critical components like engine mounts and transmission housings can affect performance.

Companies engaged in welding production often care about whether welding equipment can record data and whether historical welding parameters and counts can be viewed. The answer is yes. Nowadays, mainstream welding equipment basically comes with data - recording functions that can meet the needs of parameter traceability and output statistics.
