MMA-400 DC Inverter ARC Welding Machin

• Dual Parameter Adjustment Knobs: Includes dedicated controls for both Current (amperage control) and Arc Force to customize arc penetration and prevent the welding rod from sticking to the workpiece. • Digital LED Amperage Panel: Equipped with a bright, front-facing 3-digit display screen that shows real-time output current adjustments for exact heat management. • Smart Indicator Lights: Features built-in warning lights for power/status and overheating/thermal overload protection to ensure safe operational thresholds. • IGBT Inverter System: Utilizes power conversion technology designed for high-efficiency welding, stable arc continuity, and reduced electricity pull. • Quick-Connect Cable Terminals.
