III. Equipment Performance Highlights

(1) High-Efficiency Mass Production

• Stable capacity of 6-8 units/minute: 4× higher efficiency than traditional manual welding, producing 3,500-4,500 shelf components per shift (8 hours) to meet immediate matching needs of refrigerator production lines.
• Medium-frequency power supply advantage: Welding response speed ≤10 ms, controlling thermal loss during continuous welding to avoid overheating deformation of iron wires.

(2) Precise Welding Control

• Dynamic adjustment of welding current: Automatically matches current parameters according to iron wire thickness (2-6mm), ensuring solder joint strength ≥80 MPa with uniform weld marks and no false welding.
• Mechanical positioning accuracy: Fixture moving error ≤0.1 mm, combined with line welding process, achieving ±0.5 mm consistency control for shelf grid spacing.

(3) Durable and User-Friendly Design

• High-rigidity gantry structure: Welded body with 20# channel steel, load-bearing ≥2,000 kg, long-term operation vibration amplitude <0.5 mm to ensure welding stability.
• Human-machine interface: 7-inch touch screen (Chinese/English bilingual), supporting preset welding parameters and fault self-diagnosis (e.g., low air pressure alarm, electrode wear prompt).

IV. Industry Application Scenarios

(1) Full-category welding for refrigerator shelves

• Refrigerator compartment shelves: 2-4mm iron wire welded grid shelves, supporting one-time forming of 500×300mm to 1,200×500mm specifications.
