This Multi-Head Steel Grating Press Spot Welder is a fully automated welding workstation designed based on the customized requirements of the buyer's channel components. It operates on a "manual loading, automatic positioning, no clamping required" process, capable of automatically completing the sequential welding of all points on a workpiece in a single fixture cycle (supports simultaneous multi-point welding with adjustable specifications). During welding, a mobile platform automatically indexes, advancing the workpiece to the next station. The entire welding, indexing, and monitoring sequence is under PLC-based full automatic control, featuring automatic monitoring/alarming and fault-triggered shutdown. It delivers outstanding production efficiency, with a cycle time of approximately 50 seconds to complete a typical workpiece (e.g., 25-step welding). It is a professional solution for the high-volume, high-consistency welding production of mesh-type products like rebar mats and metal gratings

1. Efficient Fully-Automated Welding Process: The equipment is under PLC-based full automatic control. It can weld more points simultaneously using multiple heads, then automatically advances to the next row of points until all are completed. The entire process requires no manual intervention, includes monitoring and alarms, and operates on a compact, highly efficient cycle.

2. Direct Power Supply & Energy-Saving Design: Employs a method where the welding transformer supplies power directly to the workpiece, resulting in a short energy transmission path with minimal loss. Regular replacement of the welding heads maintains performance, contributing to energy efficiency.

3. Advanced Pneumatic Pre-Pressurization System: The welder uses pneumatic electrodes with automatic preload force adjustment, ensuring a relatively constant pre-pressure. Compared to spring preloading, it offers the advantages of less electrode impact, reduced electrode wear, and more secure weld points, further minimizing welding spatter and extending electrode life.

4. Intelligent Human-Machine Interaction & Management: Key electrical components are controlled by a PLC, implementing intelligent management of equipment operation. The touchscreen interface makes parameter setting, process monitoring, and operation more convenient and intuitive, significantly lowering the technical skill requirements for operators
