2. Description:
This back welding machine is mainly used for box beam to prevent large current burning through bottom of welding seam; generally used the CO2 gas shielded welding.
The main part of upper beam is square tubes and has light weight rigid good characteristic. The upper beams have guide and rack, so it makes dragging plate and welding beam moving levelly on the beam.
The cantilever box beam welding arm has two groups of two welding seam. It can welds two welding lines simultaneously. On the one hand it can drag on the board in the guide beam in translation; on the one hand, it can also drag on the plate wheel and mobile.
The welding seam tracking devices are installed below the welding arm. It can track welding line automatically to make welding torch and welding line keep proper distance. This device in horizontal direction adopts pneumatic tracking, and in vertical direction it automatically tracks by gravity.
The wire feeder is installed on the welding arm. It connects with wire plate, wire feeder and welding torch by wire tubes.
Usually we use Tangshan Panasonic CO2 welding machine( YD-600KH), also you can select other brand. For single arc single wire , need two sets welding power for one set cantilever welding machine. If double arc double wire, that need four sets for one set of cantilever welding machine.
The wire feeder is installed on the welding arm. It connects with wire plate, wire feeder and welding torch by wire tubes.
The electrical control box is install inside of vertical boom, operation panel is on the door of electric control box. The electrical control box is control the moving of cart, elevating of welding arm and power start/stop. The cart moving is frequency control. It can adjust the moving speed according to the welding technology.
