IGBT full bridge inverter technology (compared to half bridge upgrade)
Adopting a full bridge topology structure, four sets of IGBT modules form symmetrical bridge arms, achieving higher power density and current stability through high-frequency alternating conduction (50-100kHz).
Power output improvement, The full bridge structure supports higher currents (peak up to 350A) and is compatible with 5.0mm welding rods, resulting in a 30% increase in penetration depth; Energy efficiency optimization, switch losses reduced by 15%, overall efficiency>90% (half bridge usually 85%); Industrial applications, welding of ship steel plates, splicing of heavy machinery structural components (8-15mm thickness).
MMA-P2 Inverter MMA Welding Machine, it’s wide voltage input, low splash characteristics, and digital scalability make it the preferred tool for industrial maintenance, heavy manufacturing, and field work scenarios. this model has significant competitiveness in efficiency, reliability, and long-term cost control.
