Features of Welding machine NBC350 Workers - NBC500 Workers

＞Soft-switching IGBT inverter technology, small welding spatter, beautiful welding seam

＞Perfect undervoltage, overvoltage and current protection, safe and reliable

＞Classic analog large board technology, good welding performance and high reliability

＞ High-voltage slow wire feeding to start the arc, the arc does not burst the wire, and the arc ends to remove the ball

＞Constant voltage/constant current output characteristics, MIG/CO2 welding, one machine for multiple purposes

＞With arc-stop working mode, greatly reducing the operation intensity

＞Optional extension control cable, suitable for welding work in narrow and high places

＞Humanized, beautiful appearance design, more convenient operation

＞Three-proof design of key components, suitable for various harsh environments, stable and reliable operation
