Makita inverter welding machine 400A

Max Amperage: 400A output is powerful enough to consistently run large-diameter welding electrodes (like $5/32″$ or $4.0\text{mm}$ and even some $3/16″$ or $5.0\text{mm}$ rods) and weld plate steel up to about $1/2″$ (12mm) thick. Target Market: The main users are professional contractors, heavy maintenance and repair operations (like mining or shipyards), and fabrication workshops. Multi-Process Capability: Most quality 400A inverters are designed as multi-process welders:2   MIG (GMAW): Excellent for high-deposition, production welding.3 These often feature a separate wire feeder unit to handle large wire spools.4   Stick/MMA (SMAW): The most common process, using the full 400A to ensure deep penetration and high duty cycle. TIG (GTAW): Usually DC Lift-Arc TIG, which is sufficient for stainless and mild steel pipe and plate work.5
