在维修冰箱空调时,常感到缺少一套焊接设备。以往大都采用气焊,但其设备体积大、笨重、携带不便。这里向读者介绍一种微型多功能管焊机,它的体积小,重量轻、造价低、操作灵活、便于携带,是理想的冰箱空调管路焊接工具。该焊机除焊接变压器采用进口高硅钢片外(E型和口型都可以),其它和电弧焊机原理一样,这里不作介绍。 In the maintenance of refrigerator air conditioning, often feel the lack of a welding equipment. In the past mostly used gas welding, but its equipment bulky, bulky, inconvenient to carry. Here to the reader to introduce a miniature multi-function pipe welder, its small size, light weight, low cost, flexible operation, easy to carry, is the ideal refrigerator air conditioning pipe welding tools. The welding machine in addition to welding transformers using imported high-silicon steel sheet (E-type and mouth-type can), and other principles and arc welding machine, not to be introduced here.
