12IMPORTANT: If a blade has been cut by usingsnips, the ends of the blade must be groundsquare before welding them together, as shown inFigure 12.Figure 11Figure 1212.2 Removing TeethIn fine pitched blades, one or more of the teeth oneach side of the cut may need to be removed bygrinding so that the weld area of the blade isuniform and the teeth will be uniformly spaced. SeeFigure 11, and refer to section 12.5 Blade grinding.12.3 WeldingThe welder is designed forintermittent use. Repeated welding within ashort period of time may cause welder tooverheat.1. Clean welder jaws and lower jaw inserts.2. Carefully clean ends of blade which willcontact welder jaws. Remove any dirt, oil,scale and oxide.Any rust (oxide) on blade invicinity of weld must be ground off beforeblade can be welded.3. Turn pressure knob (Figure 13) to “0” position(pointed downward). NOTE: There will besome resistance when turning knob.4. Insert one end of blade into left clamp. Positionback edge of blade against back edge of leftclamp. Then position the end of the blademidway between left and right clamps. Tightenleft clamp.5. Insert opposite end of blade into right clamp.Position back edge of blade against back edgeof right clamp. Then butt the end of bladeagainst the other end of blade (the blade endsneed to be in contact with each other). Tightenright clamp.6. Set pressure selector switch (counterclockwiserotation) to the approximate setting requiredfor the width of the blade being welded.Keep hands clear of weld areaand clamp jaws during welding.7. Press and hold weld button (Figure 13). Whenweld button is pushed, the left clamp moves tothe right to apply pressure to the blade ends.Simultaneously, sparks will be emitted from theblade ends as they are being welded. Do notrelease weld button until blade joint is “redhot.”Figure 138. Release weld button, and wait 3 or 4 secondsuntil blade returns to original color. Unclampblade.9. Rotate pressure selector switch back to “0”.10. Remove blade from clamps, and carefullyinspect it. The spacing of the teeth should beuniform and the weld should be located incenter of gullet. Misalignment is easily noted atthis time from the weld appearance. SeeFigure 14 for examples of incorrect welds.11. If the weld is imperfect, refer to section 15.3 forpossible remedies to any problems. Makecorrections before annealing.
