Product Introduction

Product Features

  • IGBT Module: Heavy-duty IGBT module machine, fast dynamic response, reliable quality, stable performance.
  • One Machine with Multiple Uses: Has gas shielded welding, manual welding, and carbon arc gouging functions, one machine for multiple uses.
  • 60% Duty Cycle: 40°C, 60% (NB 500I 100%) duty cycle output, superior performance, preferred by heavy industrial enterprises.
  • Medium and Thick Plate Welding: Meets long-time welding of medium and thick plates with solid/flux-cored wires of different diameters.
  • All-position Welding: Current self-adaptive within 30mm dry extension, suitable for all-position welding.
  • Stable Arc: Droplet transfer waveform control, stable arc, less spatter, good weld forming.
  • Arc Striking to Remove Small Ball: Added arc striking to remove small ball circuit, ensuring arc striking success rate.

Application Fields: Widely used in shipbuilding, steel structures, petrochemical, engineering machinery, container manufacturing, and automobile manufacturing and other industrial fields, can meet use in extreme environments.
