OTC Argon Arc Welding Machine AEP300 & AEP500

The OTC AEP300 and AEP500 welding machines support multiple welding modes including rectangular wave AC pulse TIG, rectangular wave AC TIG, TIG arc spot welding, DC pulse TIG, DC manual welding, DC TIG, and AC manual welding.

With dynamic reactance control, these models maintain a stable rectangular wave AC current across a wide current range, from low to high.

The pulse arc power of AEP300 and AEP500 provides excellent performance on different metals and plate thicknesses, enabling high-quality single-sided and double-sided welding, as well as welding with gaps. Their advanced line energy control significantly reduces welding defects such as thermal deformation, poor fusion, insufficient penetration, cracks, and pores.

The arc cleaning width continuous adjustment feature ensures beautiful and high-quality welds on aluminum and magnesium. Additionally, initial current adjustment, current scar and drop functions, and arc crater processing enable superior welding quality.
