IGBT Invert CO2/MIG/MAG Welding Machine NB-350

Detailed Product Description

 NB series arc welding machine is suitable for CO2/MIG/MAG arc welding of low carbon steel, low alloy steel, stainless steel, AI, Cu etc.

Adopting nano-meter micro-crystal material with high magnet conductivity and low power loss, the machine achieves green environmental protection.

The technology of ZVS improves the efficiency and reliability.

Compactness and lightness, with a weight 1/5 of SCR rectifier.

LED meter can preset and display current and voltage directly.

Electronic current waveform regulation technology is adopted to control the deposition and decrease spatter (20% less than SCR rectifier).

The current feedback control system can decease current fluctuation caused by exchange of wire diameter and wire extension, thus maintain the depth of weld consistent. So it is especially suitable such as hand trembling, vertical seam, multi-layer surfacing and spaces where the torch difficult to attain.

Adopt printed motor with high torque, low inertia, stable speed and long life.
