TGA Ba 75: As TGA 75, with additional PNEUMATIC ARM for the support and movement of the gun towards the initial welding point. It allows millimetric adjustment on 2 axis. It eliminates errors or faults due to the possible instability of the hand. Thanks to the automatic movement of the gun towards the welding point, the arm is particularly suited to the orbital welding of pieces where extreme precision in required or when carrying out two or more simultaneous welding processes using two or more arms. MODEL TGA Ba 75 EM TGA Ba 75 EL Reference drawing Page 26 Fig. 3 Page 26 Fig. 3 Weight Kg. 67 67 Max. diameter of the workpiece (indicative value) mm. 350 350

TGA BaCb 75: As TGA 75 Ba, plus the following additional features:

o TAIL-STOCK: driven by a pneumatic cylinder fixed to a sliding support on the bench, which follows the orientation of the table. Extremely useful for centering and blocking the workpiece. The working length between the tail-stock and the table can be customized on request. PROVIDED WITH BIMANUAL CONTROL

o Robust BEDPLATE that guarantees high stability and, if required, allows for the fitting of a second arm for the simultaneous or non-simultaneous execution of two orbital welding processes.
