This multi Automatic Spot Welder, enables all welding heads to operate simultaneously. It delivers higher efficiency than single-head models, with uniform and neat welding spots.
Features:
As a Multi Head Welding Machine, this Automotive Spot Welding Machine adopts a multi-head structure to complete multiple welding spots in a single operation. Control system: Microcomputer control, capable of storing 15 sets of adjustable welding schedules. Operators can independently set welding parameters for one or more electrodes to meet the welding demands of products with varying sizes and shapes.
Users can self-configure the cylinder action sequence, working frequency and welding schedules to adapt to diverse product welding requirements.
The machine frame is fabricated from thick steel plates, featuring excellent rigidity and strong deformation resistance.
Equipped with microcomputer control for high precision and stable operation.
Water cooling transformer: Assembled with 15000 gauss permeability silicon steel sheets. The internal cooling structure adopts a full copper alloy core instead of aluminum core to lower impedance and boost power utilization. With a 20% duty cycle, this Resistance Spot Welder supports long-duration welding and high power output. It also boasts a longer service life, lower operating noise and a more compact, rational structure. High-speed solenoid valves accelerate the whole welding process, lifting productivity and cutting production costs.
Cylinders are made of high-precision anti-friction hard duralumin material. This material is rust-proof with low friction and noise, and enables rapid loading, effectively reducing weld spatter.
Supported by sophisticated processing equipment and exquisite craftsmanship, the machine achieves superior overall precision.
It features a low rate of loose welds and minimal welding slag.
The machine is user-friendly to operate, runs stably around the clock, and comes with a 15-year service life.
Electrodes are made of CuCrZr alloy with outstanding wear resistance. Adopting water cooling design, the electrodes enjoy an extended service life.
Compressed air system: Fitted with an air processor to purify compressed air, a muffler for noise reduction, and an air tank to stabilize air pressure.
Cooling water system: Independent cooling circuits are configured for transformers, upper electrodes, lower electrodes and other copper components. Water distribution is regulated by flowmeters, each of which supports individual adjustment to ensure stable operation and avoid equipment damage.
