High output current: Up to 350A for heavy-duty welding
Multi-process capability: Often supports MIG, MMA (stick), and sometimes TIG welding
Inverter technology (IGBT): Ensures stable arc and energy efficiency
Duty cycle: Typically around 40%–60% at full 350A output (rest time needed to avoid overheating)
Adjustable current control: Allows fine tuning for different material thicknesses
Portable design: Much lighter than traditional transformer welders despite high power
Cooling system: Built-in fan cooling for continuous operation protection
