. Overview

DM-NZZ-400B type argon arc welding automatic seam welding machine, the welding King welding power, industrial PLC and stepper motor to realize automatic welding.

The machine has the following characteristics:

1.1. uses the welding King argon arc welding power source, the arc is reliable, has the depth of penetration control function, the welding stability, the weld shape is beautiful, the welding quality is good

Using 1.2. control the operation of the whole domestic Xinjie industrial PLC, the control is accurate and reliable, simple and convenient operation.

1.3. adopts the step motor, the welding speed can be adjusted, the adjustment is convenient and reliable, the adjustment range is large, the precision is high, and the operation is stable and reliable

1.4. using three-dimensional lifting type can achieve a variety of different diameter of the workpiece welding, through the lift motor to adjust the height of the adjustment is convenient and reliable, stable and reliable operation

1.5. adopts the touch screen to input the welding length directly, and can realize the welding setting of any size in the welding range

The 1.6. front end uses the block mechanical positioning starting point, the localization is accurate

1.7. improves the work efficiency and reduces the labor intensity of workers

Two. Main purpose and scope of application

This machine is mainly used for welding seam, welding and CO2 protection welding with argon arc welding, mechanical adjustable length, different diameter cylinder welding butt welding workpiece. The parameters (working condition, spot welding, welding and debugging etc.) can be changed by the panel interface.

This machine is applicable to a variety of straight ring fan cylinder workpiece welding, can also be used for other types of products straight seam welding.
