Technical Summary

  • Superior Heat Management: The exclusive AC pulse welding method minimizes heat input to the workpiece while accelerating the wire melting rate, effectively preventing burn-through on ultrathin materials.

  • Precision Deposition Control: By optimizing the EN (Electrode Negative) ratio—up to 50%—the system achieves finer deposition control compared to conventional models.

  • Enhanced Efficiency: A higher EN ratio allows for a faster wire feed rate (up to 10.5 m/min at 50% EN ratio), ensuring cleaner welds and higher productivity.
