Products Description:

Tungsten needle are made by material with high melting point, corrosion resistance, high density, good thermal conductivity and electrical conductivity. High quality argon arc and plasma welding's important point is accurately grinding the diameter and angle of pole, our factory can product accurately tolerance and sharpen the pole, promise the pole's all tolerance. pole can be sharpened one of end or two ends .
