The "Z-NP/Z-WPN" is a beryllium copper lower chip that uses a material harder than chrome copper, making it less prone to marks from nut feet. It is particularly suitable for thin materials, has low wear, and maintains stable welding. We offer various types for "stepped type" and "rocket type." For more details about the product, please contact us. 【Features of Beryllium Copper】 ■ Harder material compared to chrome copper ■ Less prone to marks from nut feet *For more information, please refer to the PDF document or feel free to contact us.

The "LPS-YS 256" is a key-operated counter equipped with the necessary functions for spot welding. It features five counters: production count, impact count, chip exchange count, total impact count, and set value. The specifications (functions) change with the toggle of the dip switch (ON/OFF) on the back. Additionally, the buzzer sound when the chip exchange count is completed is intermittent, while the buzzer sound upon completion of production count and impact count is continuous. 【Features】 ■ Large high-brightness LED (character height 25 mm), clearly visible from a distance ■ Specifications (functions) change with the switch between lock and OFF ■ Individual relay output for production, impact, and chip exchange ■ Buzzer volume can be adjusted with a precision screwdriver ■ Low failure rate *For more details, please refer to the PDF document or feel free to contact us.

"NTW-Nut One Touch" is a height detection device that allows for one-touch setting of the up and down movement of the cylinder stroke axis of a spot welding machine. It detects NG products with height differences that differ from the settings during operation before welding (electrifying) and alerts with a buzzer and lamp. Additionally, it prevents the assembly of other parts to the product being worked on or welding with incorrect nuts. The next operation can continue after resetting. 【Features】 ■ Main unit operation specifications ■ Easy operation with one-touch setting ■ Adjustable setting tolerances ■ Extended working time ■ Display for visual confirmation *For more details, please refer to the PDF document or feel free to contact us.

The "Nut One Touch NTW-RD" is a defect detection device for various nuts, bolts, and plate components with a multi-type height condition setting function. By inputting external conditions, it switches between multiple point conditions and detects any height differences that do not meet the criteria as NG. Height differences that differ from the set height are detected before welding with a buzzer and lamp. Additionally, options such as super electrodes and super chip specifications are available. 【Features】 ■ Display with visual confirmation ■ Collect chip specification function (optional) ■ Function to set multiple heights (optional) ■ Condition switching function with external input condition numbers ■ Batch change offset function for settings *For more details, please download the PDF or contact us.

The "Super Chip" is an option used in conjunction with the Nut One-Touch. Typically, when performing two or three types of nut welding on a workpiece with a spot welding machine, processes were repeated for the number of nut types, or the number of machines was increased according to the types of nuts for production. By using this product, multiple nuts and various types of nut welding can be completed with a single spot welding machine, allowing for rationalization. 【Features】 ■ Rationalization is possible ■ Mounted and used as an upper electrode nut holder chip ■ Reduction in costs, production takt time, and defective products ■ Detects the pressure at the moment the nut is pressed, and the Nut One-Touch controls and determines the outcome ■ In case of NG, the machine stops before welding, notifies, and does not perform the welding *For more details, please download the PDF or contact us.

The "Nut Collector" is a system that detects defective products (NG) in nut welding. Defective products are detected before welding (electrification) occurs, so they are not welded. You can choose between two types: the "Collect Switch Specification," which detects defective nuts and bolts by attaching a collect chip with a sensor to the upper electrode, and the "Nut One-Touch Specification," which allows for one-touch setting of the stroke of the cylinder of the spot welding machine to detect various types of defective spot welds. 【Features (Nut One-Touch Specification)】 ■ Multi-type detection ■ The types of parts that can be detected include not only nuts but also sheet metal parts, patches, pipes, and more ■ Height can be easily set with one touch for detection ■ Detects defective products with different heights from the set height before welding ■ A dedicated one-touch chip is used for nut welding *For more details, please download the PDF or contact us.
