INQUIRY

4/0 welding cable is a single wire core, which is made of multiple strands of flexible conductors. The outer surface of the conductive wire core is wrapped with a heat-resistant polyester film insulation tape, and welding cable outermost layer is made of an insulating and sheath made of rubber as a protective layer. The 4/0 AWG electric welding machine cable uses 1702/0.30 copper wire as the conductor, and the maximum passing current is 230A.
4/0 welding cable Use characteristics:
(1) The electric welding machine cable works under the condition of low voltage (maximum voltage of 200V) and large current, and it is required to have a certain heat resistance.
(2) The long-term allowable working temperature of the cable should not exceed 65 ° C.
(3) The cable is frequently moved, twisted and cast, requiring softness and good bending performance.
(4) It is easy to be scratched and rubbed by sharp iron and steel components during casting, so it is required that the cable has good mechanical properties such as tear resistance and abrasion resistance.
(5) The use of environmental conditions is complex, such as sunlight, boiling water, contact with muddy water, engine oil, acid and alkali liquids, etc., which require certain weather resistance, oil resistance, and solvent resistance.
(6) Hot welding parts are sometimes encountered, which requires good heat distortion resistance.

(7) Frequent movement requires small outer diameter and light weight.

4/0 welding cable

The electric welding machine is a step-down transformer with a special structure. The primary side is connected to AC power 380V or 220V, and the secondary side outputs a lower voltage welding power source. Welding is the process of converting the electrical energy of the power source into thermal energy, which is used as a heat source to heat the welding metal. ; Because the workers have been dealing with the electricity in the welding operation, the more dangerous electric shock accidents often occur, so the welding machine needs a dedicated welding machine rubber sheathed cable. Choose 4/0 welding cable produced by regular companies to ensure electricity safety.
