Medium Frequency Inverter Gantry Welding Platform with Pneumatic Multi-Head Array — 40-200KVA, Aluminium and Stainless Steel Capable, ISO CE Certified

AC resistance gantry welders work well for standard carbon steel sheet metal but struggle with aluminium and coated steels. The sinusoidal AC waveform creates inconsistent heating on high-conductivity materials and burns through zinc coatings. This Xinwei MFDC gantry multi-head welder solves both problems. The Medium Frequency Direct Current inverter delivers a precisely controlled DC output with near-unity power factor. The result: consistent weld nuggets on aluminium alloys, stainless steel, and galvanized sheet metal across all heads in the gantry array. For manufacturers working with mixed materials or demanding cosmetic weld quality, MFDC is the practical upgrade from AC.
