SURFACE QUALITY:
Finish: The surface of the hafnium wire should have a high finish, without obvious scratches, pits, burrs, and other defects. The smooth surface can reduce the energy loss of the current during transmission, reduce the local discharge caused by the uneven surface, and improve the cutting efficiency and quality.
Cleanliness: The surface should be kept clean and free of impurities such as oil, dust, and oxides. These impurities will affect the conductivity and welding performance of the hafnium wire, resulting in an unstable arc and poor cutting effect during plasma cutting.
