Remove and discard the three plate assemblies (D) using a hand grinder to remove the welds. Fill and grind smooth any depressions in the frame that were made during the removal process.
Connect the ground cable for the welder directly to the actual machine component that will be welded. Attach the clamp for the ground cable as close as possible to the area that is being welded. This procedure will reduce the chance of damage from welding current to the components that follow: bearings, hydraulic components and electrical components.Do NOT use electrical components as a ground point for the welder. Do NOT use ground points for electronic components as a ground point for the welder.
