The machine is horizontal type, it is consisted of workpiece holding part (lift up down, and end fixture device), torch mechanical

control part, machine frame, MIG welding power source, wire feeder, torch lifting device, welding oscillator.It includes:


-Power shaft box,to assemble the power transmission system to drive the drop rotating.

-Idle shaft box,to withstand the drop to assure the same axis when welding.

-Centre frame,to lower the intensity of labor when drop assembled.

-Left and right oscillator,to realize the requirement of longer width of drop(Optional).

-Automatically lift&down device of torch,to realize the multilayer welding.

-Torch feeding structure,to make it easy to take the finished drop.

-Left&right tuning cross,to adjust the position of torch.

-Protection shield,to protect our eyes and to see if satisfied welding effect.

-Feeding pedestal,to assemble the wire feeder.

-Move structure of torch pedestal,to weld different position.

-Electrical operation system.
