When using arc welding power source. The cable, fuse, switch and other main accessories must be selected.
(1) cables. The welding cable often moves and bends, which requires good flexibility, easy bending, good insulation and sufficient conductive cross-section. It is usually made of multiple strands of copper cord.
(2) fuse. Fuse is a common protective device in low-voltage circuit. For AC and rectifier arc welding machine, the rated current of fuse shall be equal to or slightly greater than the rated primary current of the welding machine.
(3) switch. The rated current of AC welding machine and arc welding rectifier switch shall be equal to or slightly greater than the rated primary current of welding machine.
