Introduction to Cable and Power Selection for Welding Machines

Regulations for the use of welding machine cables: Rubber sheathed copper core flexible cables should be selected for the primary side of the welding machine, with a length not exceeding 5 meters, and rubber sheathed copper core flexible cables should be selected for the secondary side, with a length not exceeding 30 meters.

Voltage and power description: The no-load voltage of the AC welding machine is 63-72V, the working voltage is 30-44 V, the power is 17-47KW, the primary current is 26-630A, and the power supply voltage is 380V.

A DC welding machine is a structure driven DC generator by a three-phase electric motor. The secondary no-load voltage is 60V, the working voltage is 30-36V, the power is 9.5-35KW, the primary current is 45-630A, and the power supply voltage is 380/220V. Grounding wire: The metal shell of the welding machine is grounded or zeroed, and its grounding resistance value should be less than 4 ohms.
