1. With high efficiency: By shortening the length of wire electric conduction, the current and current consistency increase highly, and the capability of fusion depth and deposition efficiency are also deeply improved. Furthermore, with the protection by flux and slag, heat of arc hardly wastes, the total thermal efficiency greatly increases and welding speed can be greatly improved.
2. With nice weld quality: With the efficient isolation of slag, the main component in arc area is carbon monoxide, and it deeply reduces the content of nitrogen and oxygen in weld metal. Welding parameters can be kept stable by automatically adjusting, so the requirement to weldera??s skill is not high. The weld content is stable and machinery capability is good.
3. Saving welding material and power: With deep depth of fusion, the groove can be less in same thickness compared with stick welding, therefore the filling of welding material for weld can be reduced and power also can be saved.
4. Operating condition is better: Besides reducing operating hardness compared with stick welding, MZ machine is out of arc radiation.
