3.任何通电导体的周围都会产生磁场,因此将电缆线盘绕在焊机上,实质是给焊机绕组旁增加了一个线圈。当焊接时,这个通电线圈会产生一定强度的磁力线,形成一个磁场。它与焊机内的磁场(特别是感抗线圈产生的磁场)发生互相干扰,因此破坏了焊机原有的稳定特性,使用中会发生电压波动,电流不稳定的现象。另外,电缆线盘绕在焊机外壳上既影响焊机散热也
3. Any current conductor around the magnetic field will be generated, so the cable coiled on the welder, in essence, to the welder winding next to the addition of a coil. When welding, this coil will produce a certain strength of the magnetic lines of force, the formation of a magnetic field. It interferes with the magnetic field inside the welder (especially the magnetic field generated by the inductive reactance coil), thus undermining the original stability characteristics of the welder and causing voltage fluctuations and current instability during use. In addition, the cable wound in the welding machine shell both affect the welding machine heat also
