Description
The head is intended for fusion welding of the ends of tubes that are flush or slightly recessed in the sheet, made of titanium, Inconel and other materials sensitive to oxidation. The torch rotates without limit, and the current, shielding gas and coolant are supplied through a rotating manifold, so the cable does not twist. In the tube the head is centered by an expanding mandrel for any inside diameter, with a manual or optionally pneumatic clamp. The purge gas chamber with laminar diffusion gives welding without oxidation. Welding speed, constant or pulsed, is held by a closed loop, an encoder runs the program by position, and the return function puts the electrode into the starting position by itself. The control panel is built into the handle. The current is up to 120 A, the duty cycle is 120 A/75 %, the weight without cable is 3.8 kg, and the cable is 9 m.
How to choose
The head is suitable when the tube has an inside diameter of at least 10 mm and an outside diameter of at most 33.7 mm, with other sizes on request. The joints can be flush, recessed up to 1 mm, protruding up to 0.5 mm, in the internal bore, with a back sheet, and nozzles on headers. It is powered by the sources P4 (170 A, single-phase), P6 (300 A) and the earlier PS 164-2. If filler wire or tubes up to 75 mm are needed, look at TS 8/75. One operator can run two or three heads, and according to user feedback productivity grows by more than a third.
