Overview of Scaffolding Jack Base Automatic Welding Machine
  1. The seam welder automatic MAG/ CO2 weld the circular seambetween the scaffolding pipe with sleeve ,scaffolding pipe with base plate

2.Welding process will be continual and steady. Machine will stop automatically when the welding is finished.

3.During the welding ,welding torch is fixed, while the work-piece is rotate

5.Use Japan OMRON PLC to control and achieve the welding process, improve reliability.controls the whole machine operation. stable control and stable programming interface.

  1. 6. MCGS Touch screen as the input and output interface.The welding mode and welding specification can be preset, saved and re viaMCGStouch screen, it is convenient to modify the parameter and switch the status through the man-machine touch screen.

7.Welding process will be continual and steady. Welding seam appearance is good and smooth, the depth of fusion and width of fusion meet the welding requirement, leakage rate is less than 1%

8.The welding mode and specification can be preset, saved and recalled via touch screen. it is convenient to modify parameter and switch the status. Welding length, arc igniting, arc ending time.

9.You can do simulation welding process through the touch screen to see the welding process ,then adjust the welding parameters to the suitable value before start the real welding ..

  1. Main connect of the program: Welding parameter, Welding monitor, Fault detection, Maintenance, I/O monitor, Contact Us, Company introduction
Machine Configuration
