The length of wire on the two side of arc welding machine shall not be more than several meters
The length of the two side wire of AC arc welding machine shall not be greater than 30m.
The length of the wire is 100 meters. But the welder must use BX1 or BX3, ZX5 and so on. That is to say, the output voltage should be higher. General 75-80V is easy to use.
The longer the fever rises. So it's better to lengthen the side.
As long as it does not affect the quality of welding, how much can be,In order to reduce the pressure drop, the two line should be as short as possible, but for safety, safety requirements of a line of not more than 5 meters.
