当前随着焊接技术的发展,弧焊机的种类,型号不断增多。但是目前使用着的老产品——BX-330交流弧焊机,由于该焊机具有构造简单,维修方便,适应性强及耐用等优点,仍得到广泛的应用。特别是在一些中小企业里用得更为普遍。 BX-330交流弧焊机的电流粗调在次级接线板,采用Ⅰ、Ⅱ两种方法,用一连接铜板来改变二次线圈的圈数以达到调节电流的目的。但在实际生产中,拆卸铜连接板有些不便,稍不注意,还容易打火,
With the current development of welding technology, arc welding machine types, models continue to increase. However, the old products currently used - the BX-330 AC arc welding machine, is still widely used due to its advantages of simple structure, easy maintenance, strong adaptability and durability. In particular, it is more common in some SMEs. BX-330 AC arc welding machine coarse-grained current in the secondary wiring board, using Ⅰ, Ⅱ two methods, with a copper plate to change the number of turns in the secondary coil in order to achieve the purpose of regulating the current. However, in actual production, disassembly of the copper connecting plate somewhat inconvenient, a little less attention, but also easy to hit the fire,
