630 of the transformer, there are five low-voltage interface, and ask experts to tell how much the main line, the distance is 100m, tube laying, it is best with a calculation method
How much you need most is not the total power, but the maximum wire conduction current in electrical will usually determine type of cable per square mm 5A around the level, usually in order to have a safety margin, electrical engineer of our company are in accordance with the standard of 4A per square millimeter cable selection.
Some 50 square flash welding line, 1.5 square wire bending machine and machine fault is enough, but consider other problems with 2.5 square line. 16 square cable for electric welder.
For the electric welding machine, the influence of heating is fully considered, and the influence of the maximum welding current on the continuous output is considered
