Advantages of DNW3 series Efficient batch welding: multiple electrodes work synchronously, and dozens of welding joints can be completed at one time, which is 5-10 times more efficient than a single spot welding machine, suitable for mass production Stable welding quality: the pneumatic pressurization pressure is uniform and adjustable, avoiding the instability of manual pressurization and ensuring the consistent pressure of each welding joint; Synchronous current control technology reduces the current diversion between solder joints to ensure uniform size and strength of each solder joint melt core. Adapt to large/long size workpieces: The gantry structure has a large opening, which can easily accommodate long mesh, large frames and other workpieces, solving the limitations of ordinary welding machines on the size of workpieces. Easy operation and high degree of automation: through the control system preset parameters, one key start welding, reduce manual intervention; With automatic feeding and positioning devices, it realizes fully automatic production and reduces labor costs. Strong structural rigidity and good durability: the gantry is welded by thick steel plate or cast steel, which has strong resistance to deformation and can maintain accuracy even after long-term use; The electrode and pneumatic parts are made of wear-resistant and high-temperature resistant materials for a long service life. Industry Applications Metal mesh products: construction steel mesh mesh, guardrail mesh, breeding cage net (chicken cage, rabbit cage), storage shelf mesh, coal mine support net, etc. Frame and structural parts: elevator car frame, automobile/agricultural machinery protective fence, steel structure support, photovoltaic bracket connector, storage pallet frame, etc. Hardware and daily necessities: bicycle/electric vehicle frame grids, metal furniture (such as bed frames, shelves), kitchenware grids (such as disinfection cabinet shelves), etc. Building materials and security: anti-theft windows, protective nets, blind skeletons, subway/high-speed rail platform guardrails, etc. Weldable material mild steel (e.g. Q235): Most commonly used, excellent weldability and high solder joint strength. Stainless steel (such as 304, 201): With special copper alloy electrodes (anti-sticking), suitable for scenarios with high corrosion resistance requirements Iron wire/steel wire (usually 0.5-10mm diameter): widely used in mesh products, with obvious advantages in welding efficiency. Low-alloy high-strength steel: suitable for structural parts (construction machinery frames) that require strength.
