Page 27: Build Up & Hardsurfacing
Hardsurfacing must be inspected and maintained. For hardsurfacing, LaBounty recommends; • FabTuf 960 or equivalent If you have questions about what hardsurface material to use, contact LaBounty Customer Service at 1-(800) 522- 5059. Guidelines • Connect the ground pole of the welder to the part to be welded, as close as possible to the welding area. The ground pole must be connected so that the current does not cross the hinges or the hydraulic cylinder. - Page 28 Wear Plates 28 | MRX Multi-kit Demolition Tool Operation & Maintenance Manual...
