CHAMP T 400 – Rugged Power for Precision Welding

The CHAMP T 400 is a robust, inverter-based DC welding rectifier built by Ador Welding Limited, India’s leading welding solutions provider. Engineered for demanding fabrication and project environments, it delivers up to 400 amps of smooth, stable welding current suitable for MMA (Stick) and optional DC TIG applications.

Built with advanced IGBT inverter technology, the CHAMP T 400 offers high power efficiency, superior arc control, and the ability to run long welding and return cables (100 m + 100 m) without performance loss. It handles all types of electrodes – including 6010, 7010G, and 8010G – making it ideal for pipeline, structural, and maintenance work.

Rugged construction with IP 23 protection, arc-force adjustment, and comprehensive safeguards (against over-voltage, under-voltage, single-phasing, and over-temperature) ensure reliability even in harsh industrial conditions.
