  • Page 24: Understanding The Welding Cycle

    Understanding the Welding Cycle On the SW2000, a cycle consists of five stages: sizing and clamping, burn-off, heating, fusing, and cooling. In the sizing and clamping stage, the operator loads the rear piece and moves the Manual Head so the mitered end of the piece is 1/2” from the edge of the weld table.
  • Page 25 To weld the remaining two corners, the operator loads the rear piece and turns the partially welded unit around. The process begins again at the sizing and clamping stage. Operation • 3-3 SW2000 Twin Point Welders Copyright © GED 2006 IM-0068 Rev A...
