1. Cable aging (long-term cable at high temperature operation, will lead to increased cable impedance value, affect welding parameters)
2. Cable short Circuit (because the position of the torch job is not the same, the angle of the operation is also different, the distortion of the cable is also increased, resulting in short circuit)
3. Leakage of cable （1. Terminal Place 2. Cable insulation Sleeve Rupture）
4. Cable insulation sleeve breakage (work in the long term and auxiliary equipment wear, cable operation Long distortion will cause damage)
P.S. Each of our torch will be tested before it leaves the factory.
