  • Page 38 Note: To make a proper blade weld, the ends of the blade must be evenly butted together during the welding process. If necessary, use Figure 45 the grinder to square up the ends or remove any teeth that are in the welding zone (see Figures 43–44).

  • Page 40 Note: Make sure not to grind the teeth or blade body, or overheat the blade during NOTICE grinding—this will weaken the blade. For good metal-to-metal contact between the welding clamps and the blade, make sure the blade material and the clamps are Step 14 free from any debris or flash before and after each use of the welding station.
