Features and Benefits

  • Effectively reduce the number of welding layers and passes, as well as inter-layer cleaning and other auxiliary time. The total efficiency can reach 3 times of single wire welding.
  • Best choice for thick plate welding, which can realize welding  medium plate less than 25 mm without back chipping and grooving. Reduce the welding costs more than 60%.
  • Under the condition of same welding heat input, three-wire SAW enjoys higher deposition rate and welding speed. Deposition rate: 31.7kg/h.
  • Under the condition of same line energy welding time is 68.7% of that of tandem SAW.
  • DC arc of anterior wire ensures penetration, and AC arc of posterior improves welding seam formation. The parameters of three wires  can be adjusted separately, which brings convenient parameters  presetting. It can meet more technical requirements.
  • Three full digital inverter power sources make it enjoy high efficiency  and energy saving.
  • DC and AC power sources can work simultaneously or individually,  which meets different requirements of welding.
  • lt is suitable for welding thick plate of more than 20mm
