Material and time saving: reducing the number of welding layers and passes, so as to reduce inter-layer cleaning and other auxiliary time

Greatly improved total efficiency: 3 times that of single-wire SAW

Saving more than 60% of welding cost: requiring no grooving and back chipping when welding plates no thicker than 25mm

Highly efficient: higher deposition rate and welding speed under the same welding heat input (deposition rate: 31.7  kg/h)

Much faster: 68.7% welding time spends of that of TANDEM SAW under the same welding line energy

Convenient parameters presetting: DC arc for penetration and AC arc for improving weld formation; all parameters can be adjusted separately to meet more technical requirements

Energy saving: three fully digital inverter welding power sources

Meet different welding requirements: DC and AC welding power sources can work simultaneously and individually

Thick plates welding expert: applicable for plates thicker than 20mm
