This device utilizes submerged arc welding, which does not emit light and has a fast welding speed. In addition, it is convenient and quick to manually adjust polygonal rods. The welding machine power supply is produced by Shanghai Welding Machine Factory, with uniform, continuous and beautiful welds, strong penetration, one-time forming, high welding efficiency, and a speed of 1-3 meters/minute, which is three times that of gas shielded welding. The welding cost is lower than gas shielded welding, and it is currently the fastest, most effective, and lowest priced equipment in the domestic lamp post industry.
