Dual-nut double spot welding machine, capable of welding two different types of nuts automatically during operation, featuring automated welding. This method is cost-effective and convenient, widely used in auto parts factories, and allows for multi-functional use of a single machine.

Welding is performed using a medium-frequency inverter spot welder, with one nut feeder on each side.

Overview of Intermediate Frequency Spot Welding Machine:

The equipment is equipped with a gas reservoir to stabilize the gas pressure source. The intake is fitted with a pressure switch that features low-pressure alarm functionality and can provide a cutoff signal. It also has low-water pressure and insufficient water flow alarm capabilities, with a cutoff signal as well. The water circuit is part of the equipment's welding and cooling system. It is responsible for cooling the inverter, medium-frequency transformer, and welding head sections.

The waterway system is primarily composed of flow-through pipes, piping, water filters, and collecting plates.

Introduction to Medium Frequency Inversion

Utilizing PLC control action programs, the human-machine interface displays operating parameters, set parameters, and manual/automatic selection. Multiple programs can be stored for ease in welding products of different specifications. Multiple inductive switches ensure that if there is no workpiece or if the workpiece or cylinder is not in place, the next program will not activate.

Introduction

Medium Frequency Power Supply System: Comprised of medium frequency inverter controllers, medium frequency inverters, and medium frequency transformers, etc. The medium frequency controller performs automatic detection, automatic welding, step-by-step reset, and safety protection functions through programmed software instructions and various parameter settings. The HJ-MF controller utilizes microcomputer control and multiple programs, featuring automatic power factor correction, transformer overheating protection, voltage fluctuation compensation, and is designed with commonly used operating parameters for ease of operation. The medium frequency inverter is developed by integrating advanced German technology with years of welding experience, and its main inverter components include:All IGBTs, SCRs, and driver modules are made with imported German components, ensuring reliable and stable quality; Medium Frequency Controller: This controller utilizes microcomputer control, allowing for advantages such as automatic power factor correction, transformer overheating protection, and voltage fluctuation compensation. It features full Chinese display and includes common working parameter settings for easy operation.
