Automatic Flash butt welding machines- with picking-up welded rims devices

Working/Process flow: 

Preparation before welding → Mannually putting into the workpiece → Mannually pressing down the press arm → start the welding power supply → pulse  → Release the press arm to take out the workpiece feeding → clamping → (multiple) preheating → (pulsating flash) sintering → Release → moving clamp return → welding completion.

Remarks: During the flash-butt wedling process, even equipped with picking-up welded rims devices to next processing machines, Mannually putting into rims to welders, mannually pressing down the buttons are still necessary.
