NB-M31N ZERO S

Welding mode: Horizontal fillet

NB-M31N Zero S meets the demand of field welders to eliminate straight unwelded portions that had to be manually welded in the past. When the torch reaches the center point after start of swing, the carriage starts. When the carriage is stopped by a stopper such as wall or block, the torch swings again heading for the final end point. The weld start and end points can be freely changed depending on specific welding applications.
