The MoTion Weld processes are particularly suitable for thin plate applications and for components with varying gaps and tolerances. The welding processes provide advantages everywhere where special demands to weld surface and appearance are made. MoTion Weld is a combination of the proven CLOOS processes such as Control Weld or Vari Weld and reversing wire. Here, a mechanical system draws the wire back and forward at a high frequency. Thus short circuits can be interrupted cleaner and with less energy than in the case of short arcs without reversible wire electrode.
