At room temperature, the currently used conductive materials such as copper core welding cables have resistance. When current flows through the welding cable, a voltage drop is generated. The power consumed by this section of the cable is the product of the current flowing through the cable and the voltage drop across the cable. People generally think that using thin cables is more economical and cheaper than thick cables, but they tend to ignore the fact that after the cables are put into use, they will pay for the electricity consumed by the cables, that is, they will pay annoying electricity bills. So, how to effectively reduce the welding energy consumption and reduce the power consumption of the cable?

Method 1: Use thick cables instead of thin cables

In the case of the same welding current, the life of the thick cable insulation jacket will be longer than that of the thin cable. Because the thick cable has lower resistance and lower loss than the thin cable, the thick cable will also generate less heat. This means that the update cycle of thick cables is longer than that of thin cables, and it is actually more economical to use thick cables.

Method 2: Use short cables instead of long cables

It is more economical to use a shorter cable generally , but people prefer to use a longer cable in actual operation, which causes the cable margin to be too large. Too long cables will not only cause waste of cable purchase fees and electricity bills, but also increase the cost of purchasing cables and electricity, but also the work of the welder at the end of the working day to process and collect cables consumes more energy. Therefore, in determining the length of the cable, it should be selected relatively accurately according to the actual situation.
