MR400

The MR315 and MR400 utilize constant current characteristics to maintain a highly stable arc, ensuring consistent weld quality. The integrated Arc Thrust function effectively prevents electrode sticking, facilitating a seamless and smoother welding operation. With a high rated load factor, both models are engineered to provide sustained, powerful performance specifically suited for welding medium to heavy plates.
MR400

Main Features

  • IC-Thyristor Technology: An ideal DC Arc welding machine featuring a stable arc and reduced spatter.
