Product Details

Next-generation SiC efficiency with true continuous-duty output for industrial MMA welding.

The official Taumaco page positions MMA-400SiC as a silicon carbide inverter welding source delivering 330A at 100% duty cycle, 85% efficiency, hot start and arc force functions, long-cable support up to 50 meters, and stable continuous operation in industrial environments.

Silicon Carbide Advantage

  • Uses next-generation silicon carbide power semiconductor technology.
  • Officially described with 85% efficiency and enhanced thermal performance.
  • High inverter frequency is positioned to deliver smoother welding with reduced spatter.
  • The SiC platform is presented as a major upgrade in welding power-source design.

Continuous Welding Performance

  • 330A output at 100% duty cycle enables continuous operation without cooling downtime.
  • Arc Force and Hot Start functions support penetration, easy ignition, and weld quality.
  • The product page also highlights smooth low-current operation with reduced spatter.
  • At only 11.3 kg net weight, it combines continuous-duty capability with a compact footprint.

Compatibility & Workspace Range

  • Compatible with 3-phase power systems and generators across a 320~415V input range.
  • Works with welding rods from Phi2.5 mm to Phi5.0 mm for wider application coverage.
  • Supports welding cables up to 50 meters for more flexible jobsite reach.
  • Air cooling, overheat protection, IP21S enclosure level, and H-grade insulation support industrial deployment.

Applications & Advantages

  • Ideal for remote construction sites where generator use and long cable runs matter.
  • Well suited to heavy industrial manufacturing because 100% duty cycle supports uninterrupted production.
  • Useful for precision welding tasks where arc-force and hot-start control improve weld quality.
  • Main advantages are SiC efficiency, uninterrupted 330A output, and strong field-ready flexibility.
ARC / MMA / BX1 Series

Select mini inverter, portable MMA, industrial DC stick, or transformer and SCR arc welders by input supply, duty cycle, and job demand.

This arc-welding lineup covers compact ARC mini inverters, standard MMA inverter models, high-output IGBT and SiC industrial power sources, SCR heavy-duty DC machines, and BX1 or transformer T-series AC welders for structural steel, repair work, and workshop production.

ARC Mini And Portable MMA

  • ARC120, ARC140, ARC160, and ARC180 cover portable DC inverter arc welding for mobile service and everyday repair work.
  • MMA 3.2, MMA 4.0, MMA 5.0, MMA 160, and MMA-160H extend portable MMA coverage for general electrode welding tasks.
  • Choose this group when easy transport, simple setup, and routine stick-welding flexibility matter most.

Workshop And Industrial DC Models

  • MMA-160D, MMA 200, MMA-200D, MMA 250 1-PH, MMA 250 3-PH, and MMA-250D serve workshop and site welding with broader output and input options.
  • MMA-400IGBT, MMA-500IGBT, MMA-630IGBT, MMA-400SiC, and MMA-500SiC support heavier DC arc welding for fabrication, production, and industrial work.
  • Select this group when higher current reserve, longer duty performance, or generator-friendly industrial inverter capability is required.

Transformer AC And SCR Heavy Duty

  • BX1-400, BX1-500, BX1-630, MMA-400T, MMA-500T, and MMA-630T represent transformer AC arc welding for durable heavy fabrication use.
  • MMA-500SCR and MMA-630SCR add higher-output SCR-controlled DC arc welding for demanding industrial steel applications.
  • These models fit buyers who prioritize robust machine construction, stable high-current output, and conventional heavy-duty workshop layouts.
