Features
A precision 50KVA resistance welder for fusing dissimilar copper (Ø6–10mm) and aluminum tubes (0.5–1.5mm thickness) in 5–7 seconds per joint. Optimized for HVAC, refrigeration, and automotive heat exchangers, it combines PLC-touchscreen controls, 8-grade voltage tuning, and a compact 800×550×1520mm frame to deliver aerospace-grade bonds with repeatable reliability.
Dissimilar Metal Welding Expertise
Proprietary resistance algorithms overcome conductivity differences between copper and aluminum, preventing brittle intermetallic formation. Air-cooled electrodes (0.5–0.6MPa pressure) ensure <5% porosity rates across 0.5–1.5mm wall thicknesses.
Adaptive Voltage & Cycle Control
Eight-step voltage grading (380–450V input) fine-tunes thermal input for Ø6–10mm tubes via touchscreen presets—eliminating under/over-weld defects in mixed-material production batches.
Rapid PLC-Guided Automation
Integrated Siemens PLC reduces cycle times to 5 seconds/joint while storing 200+ weld recipes. Real-time current/force monitoring auto-adjusts parameters mid-cycle for zero scrap output.
Lean Manufacturing-Ready Footprint
The 600kg unit occupies 0.7m² yet handles 50KVA loads, featuring tool-less electrode swaps and embedded IoT ports for OEE tracking in Tier 1 automotive assembly lines.
