  • Can draw simultaneous AC power while welding
  • Amazing voltage regulation @ 1.5% (+/-)
  • Tier 4 final Kubota diesel – Model D722
  • Arc Force control allows the operator to fine tune DC current during low voltage welding conditions which helps in preventing electrodes froms sticking during short arc length welding
  • Smooth arc characteristics and more consistent, quality weld penetration
  • E-mode improves fuel efficiency by allowing one operator to weld up to 160 amps while the engine maintains idle speeds.
  • SMAW, FCAW, GMAW, GTAW and ACAC welding processes
  • Sound attenuated cabinet reduces noise output to 59 dBA @ 23′
  • External fuild drains for easy maintenance
