The ZX7-400 packs serious welding power into a portable IGBT inverter package — just 25kg yet capable of running 4.0mm electrodes. Dual voltage auto-detection (220V/380V) means you can plug into site power or a generator without reconfiguration.
Smart arc features include anti-stick, adjustable arc force, and hot start for smooth ignition with difficult electrodes (E6010, E7018). Wide voltage tolerance makes it ideal for construction sites, field repairs, pipeline work, and remote locations where power quality is unreliable. EU CE certified.
