BX3 series AC arc welding machine is independently developed and produced by our company. The welding machine has the advantages of simple structure, easy maintenance and repair, low price, light mobility, high efficiency and low working cost. The welding machine can adopt Φ2~Φ8mm coated welding rod, which is suitable for welding thicker steel structures with large current, and can also be used for electric cutting.
The BX3 series AC arc welding machine is a single‑phase, moving‑coil type power source designed for manual operation by one person. It is suitable for welding low‑carbon and low‑alloy steel components and can also be used for electric cutting. The machine accepts coated welding electrodes ranging from 2 mm to 8 mm, delivering high current for thick steel structures.
The manual lists the main technical parameters, including a 380 V power supply, 50 Hz frequency, rated input current up to 120 A, and rated welding current up to 630 A. It also provides ordering guidelines, specifying that customers must indicate the machine type, voltage level, current rating, pole number, operation mode, and quantity when placing an order. This manual is written in Chinese.
