1. The fresh butt welder repeats scattering of contact arc of the covered electrode to even out the contacting surface, removes impurities and pressurizes to make deposition.

2. As the heating range is narrow, there is less thermal deformation.

3. The strength of welding zone and welding reliability is high.

4. It can weld even those difficult to up-set butt weld such as pipe and thin plates with wide welding zone or thin thickness. 

Detailed Purpose and Suitability 

It is suitable for welding stainless steel, aluminum, low alloy steel, soft metallic rods, wires and pipes.

It is widely used in vehicles, electric machines, railroad cars, bicycles, aircrafts, steel and construction.

It can evenly heat up the welding zone and remove impurities for reliable welding operation, and can excellently weld dissimilar metals such as special steels without being affected by welding materials with large cross sectional area.
