COMMON WELDING PROCEDURES | | |
Set the oscillation speed and the rear and front dwell times as called for in the welding procedure. The front dwell time controls the dwell when the nozzle is at the proximity sensor farthest from the Spreadarc mount- ing bracket (right-side when facing the Spreadarc User Interface). The rear dwell time controls the dwell when the nozzle is at the proximity sensor closest to the Spreadarc mounting bracket (left-side when facing the Spreadarc User Interface). The oscillation dis- tance, or sweep length, is controlled by rotating either or both of the proximity sensor stops as required giv- ing proper front and rear electrode position. After the desired oscillation track is obtained, lock the stops in place by tightening the hex nuts against the stops.
In order to protect the Spreadarc from high tempera- tures, best welding practices would be to set the travel direction such that the unit moves away from the heat of the arc, instead of over it.
