ZD series automatic submerged arc welding machineDetailed product description：

The ZD series automatic submerged arc welding machine is an automatic welding equipment that uses an arc to weld under the flux layer. It is widely used in industries such as steel structures, boilers, pressure vessels, pipelines, petrochemical equipment, shipbuilding, and machinery manufacturing for automatic welding of medium thick plates, low carbon steel, and high-strength steel.

The welding power supply using thyristor rectification is stable, reliable, energy-saving, and easy to adjust. Welding power sources have the external characteristics of gradual reduction, high welding current density, high thermal efficiency, strong penetration of arc, fast welding speed, high weld quality, and beautiful forming. Welding power sources are suitable for various purposes such as automatic submerged arc welding, electrode arc welding, carbon arc gouging, etc. The automatic welding cart is easy to adjust, suitable for various occasions and angles, easy to replace welding wire, easy to maintain, and has high production efficiency.
