Maxmech Inverter Welding Machine MMA-250 250AMP
KSh 13,999.00
Key Operational Features
-
Higher Duty Cycle & Deeper Penetration: Capable of running 4.0 mm electrodes continuously without reaching thermal cutoff as quickly as lower-amperage units.
-
Hot Start & Arc Force: Features automatic Hot Start for easy arc striking on rusty or painted surfaces, along with Arc Force adjustment to prevent electrodes from freezing to the workpiece during deep penetration welds.
-
Heavy-Duty Cooling Architecture: Enclosed in a rugged chassis equipped with high-speed cooling fans and internal aluminum heat sinks designed for long operational cycles in hot workshop environments.
Maxmech MMA-250 is a commercial-grade, heavy-duty IGBT inverter DC stick welding machine. Delivering up to 250 Amps of current output, it provides increased thermal headroom and higher penetration depth compared to the 200A models, making it ideal for structural fabrication, thick steel plates, piping, and continuous workshop use.
