Features:
This Automatic Spot Welder adopts a multi-head structure, enabling multi-spot welding in a single operation. Control system: Equipped with microcomputer control, it can store 15 sets of welding schedules that support independent adjustment. Operators can easily set separate welding parameters for one or multiple electrodes, perfectly meeting the welding demands of products with varying sizes and shapes. As a reliable Resistance Spot Welder, it delivers flexible parameter configuration for diverse production needs. Users can independently set the cylinder action sequence, operating times and welding schedules to adapt to the welding requirements of different workpieces.
It is fitted with a large display screen for intuitive and clear data viewing.
Parameters are set and adjusted via touch switches, ensuring simple and efficient operation.
The machine frame is fabricated from thick steel plates, featuring excellent rigidity and strong resistance to deformation.
Water cooling transformer: Assembled with silicon steel sheets of 15000 gauss permeability, this component adopts a full copper alloy core instead of an aluminum core, with circulating cooling water inside. It lowers impedance and improves power utilization. With a 20% duty cycle, this Spot Welding Machine supports long-duration continuous welding and delivers high output power. The transformer also boasts a longer service life, lower operating noise and a compact, rational structure. High-speed solenoid valves accelerate the welding process, boost overall productivity and effectively cut production costs.
The cylinders are made of high-precision, wear-resistant duralumin material, which is rust-proof and creates minimal friction and noise. Faster cylinder movement also helps reduce weld spatter.
Supported by advanced processing equipment and exquisite craftsmanship, the machine achieves superior machining precision.
It features a low rate of loose welds and produces minimal welding slag.
The equipment is user-friendly to operate and runs stably around the clock, with a designed service life of 15 years.
Electrodes are made of CuCrZr alloy with outstanding wear resistance. Combined with water cooling design, the electrodes enjoy an extended service life.
Compressed air system: An air processor is installed to purify compressed air, while a silencer reduces operational noise. A built-in air tank maintains stable air pressure for consistent performance.
Cooling water system: It provides dedicated cooling for transformers, upper electrodes, lower electrodes and other copper components. Water distribution is regulated by independent flowmeters, which can be adjusted separately to guarantee stable operation and prevent equipment damage.
This equipment is widely applied in the production of wire mesh, storage racks, protective fences and other products.
