**Do the standard specifications require that the length of the primary wire of the welding machine be less than 3 meters? This requirement seems unreasonable; is such a demand really necessary for deterrence? It seems that in practice, no welder can guarantee this, right?
From what I understand, **the standard specifications do not explicitly require that the length of the primary wire of the welding machine be less than 3 meters. In practical applications, the length of the wire connected to the welding machine can be designed and adjusted as needed. This requirement might be a misunderstanding or a special regulation in certain places. When using a welding machine, welders should pay attention to the safe use of wires, avoiding safety hazards that may arise from overly long wires. At the same time, welders should also take appropriate safety precautions based on the actual circumstances, such as using welding masks correctly and wearing protective clothing. .
