Circumference / straight seam welded dual. Transformers, electrodes, copper wheel, SCR uses water cooling, greatly improved the life of the equipment. The equipment used for the barrels towers at both ends of the cover straight seam welding and girth welding, soldering really effect change, weld appearance sealing, watertight, easy to operate, easy to adjust. 1, the new DC friction welding seam water tower by my company new improved from the original with a large copper axes, large copper tile to the conductive structure, change Post new friction conductive copper to copper wheel mode to reduce head loss, increase the conductivity, greatly reduce the customer later use costs, maintenance costs, more compact head, uses the most advanced DC welding process, welding using direct current to the water tower, the traditional exchange seam welder, large power transformers, low utilization rate , DC tower seam welder, welding the same thickness saving: 30%, making a large holding tank only then: 25 square wires can be normal production, reduce the cost of the investment environment for investors. (No separate power supply Transformer). 2, frequency variable speed, high efficiency, speed and stability, transmission mode may be used: chain drive motor, the motor gear, hydraulic transmission, enabling customers to adjust the welding speed.
