I Application and features

1.LPG LPG Cylinder Automatic welder automatic Submerged Arc welding the circular seam between the tank body head and bottom

2.During the automatic welding ,the welding torch is fixed; the cylinder rotating drive by head stock servo motor, welding position is horizontal.

3.the welding torch adjusting mechanism can move left and right on the beam ,and tail stock can move left or right on the machine base,to meet different size cylinder welding .

4.The welding torch can be adjusted up and down, left and right, dip angle, in order to meet the welding requirements.

5.PLC control the machine to finish the welding process as program ,easy to control ,get good weldng performance .
