China Aluminum Fuel Tank Welding Machine
1.aluminum fuel tank welding machine is designed to weld fuel tank square seam. 
2.Tank length: 700-2000mm.
3.The welding seams are irregular. 
4.Pulse MIG welding
5.CNC welding system
6.Finland KEMPPI digital welding power source
7.CNC servo system makes sure that the welding linear speed is the same during the whole welding process. Welding torch walks out of welding seam path when the arc is burning continuously, to realize the normal welding of fuel tank square seam. 
8. Arc tracking is designed to guarantee the distance and angle between welding torch and workpiece does not change in the tank rotation process. 
9. Oscillator is designed to offset rectify and weld big seam.
