Automated High Speed Condenser Welding Machine with Adjustable Effective Width for Wire Tube Condenser Production Line
Product Overview
The Automated High Speed Condenser Welding Machine is a gantry-type multi-head spot welding system engineered for high-volume wire-on-tube (WOT) condenser manufacturing. Designed specifically for refrigerator, freezer, and commercial refrigeration production lines, the machine delivers precise, consistent wire-to-tube welds at industrial scale.
Equipped with multiple synchronized welding heads and a servo-driven double-layer feeding system, the machine executes the entire welding cycle automatically after material loading—from wire positioning to multi-point simultaneous welding and fixture exchange. The adjustable effective welding width accommodates a wide range of condenser panel sizes, eliminating the need for dedicated tooling changes between product specifications.
Key Advantages
Fully Automated Welding Cycle
Once the operator loads the serpentine tube and steel wires onto the double-layer feeder and presses the start button, the machine executes the complete welding sequence autonomously—including fixture stepping, multi-head simultaneous welding, and automatic fixture exchange. The dual-layer feeding system allows one fixture to be loaded while the other is being welded, enabling uninterrupted batch production and maximizing throughput.
Adjustable Effective Welding Width
The effective welding width is freely adjustable to accommodate various condenser specifications without mechanical modification. Whether producing narrow condensers for compact refrigerators or wide panels for commercial display coolers, a single machine handles the full product range—reducing capital investment and floor space requirements.
Multi-Head Gantry Welding System
Multiple welding heads operate simultaneously, dramatically reducing cycle time compared to single-head alternatives. Each head is pneumatically actuated with individually controllable welding parameters (current, time, pressure), ensuring uniform weld quality across the entire condenser panel.
Intelligent Welding Parameter Management
101 stored welding models with quick-change capability for rapid product changeover
3 selectable pressurized curves for different material combinations
PLC-controlled with color touch screen HMI for intuitive operation
Medium-frequency inverter DC (MFDC) power supply delivers precise, fast current adjustment with minimal thermal impact on surrounding material. Features include higher power factor (0.85-0.90) compared to conventional AC systems, three-phase balanced load with minimal grid interference, and maximum secondary short-circuit current up to 40 KA for reliable wire-to-tube fusion.
Voltage Stability Under Factory Conditions
Built-in network voltage floating compensation ensures that when input power fluctuates within ±10%, the secondary output voltage remains within ±3% of its set value—critical for maintaining consistent weld quality in facilities with unstable power supply.
