COMPARISON RAVITEX® TECHNOLOGY
Sinterleghe in recent years has developed the design and manufacturing know-how to build tools for dressing removal controlled. This feature, coupled with the ability to shape also the active electrode, allows to determine the overall life of the electrode by improving the quality of the welding point can be obtained, associated with a reduced weld spatter and reducing energy consumption of welding. The technical features of this cutter have allowed Sinterleghe to obtain patent # EP2193003.

The contemporary use of this cutter and our exchange-automatic electrode SCA-SRE DELTA patent # 0001338264, made it possible to raise the quality and production standards achieved to date. The shape of the electrodes stirred, dressing cycles of change-electrode has been set and defined by Sinterleghe S.r.l. as: "RAVITEX® TECHNOLOGY Patent # EP2193003 & 0001338264"
