Makita inverter welding machine 400A

The 400 Amp output signifies a machine capable of handling significant welding requirements: 3 Industrial Strength: This amperage is typically used for heavy metal fabrication, structural steel work, pipeline welding, shipyard maintenance, and repairing thick sections of machinery and heavy equipment. 4 Thick Material Capability: A 400A machine can efficiently run large-diameter welding electrodes (like 5 $5.0\text{ mm}$ or even $6.0\text{ mm}$ for Stick welding) and handle high-deposition MIG and Flux-Cored welding on very thick plates. Inverter Efficiency (IGBT): Unlike old transformer-based welders, the inverter design (often utilizing IGBT technology) makes the 400A machine much lighter, more compact, and consumes significantly less power for the same output. 6 Input Power: Most true 400A industrial welders require a Three-Ph ...
