Mobile Welding Machine for Welding Rotary Symmetric Parts

Rota-Welder 21 – Mobile Welding Machine for Welding Rotary symmetric Parts

The Rota-Welder is a mobile welding machine for high-quality repair of weared bores and shafts.


  • No time-consuming and material-intensive manufacture of sockets for setting into worn out non-circular or non-centric bores!
  • With the solenoids, which are integrated in the base, you can apply the machine very fast!
  • No wastage of expensive welding material as its application is infinitely adjustable by potentiometer. Very little material is then removed in the subsequent machining process!
  • Best quality of the welding seam by constant welding speed!
  • You can even repair very small workpieces easily with the Rota-Welder, though you could not work manually!
  • You can use any MAG-welding machine!

Because of these advantages you can save lots of money, you would spend on machines and workers if you do it the way you used to do!
