3. Position blade so that cut is made at a place that
allows for uniform spacing of teeth. See Figure 12.
4. Bring handle down fi rmly to cut blade.
IMPORTANT: If a blade has been cut by using snips,
the ends of the blade must be ground square before
welding them together, as shown in Figure 14.
12.2 REMOVING TEETH
In fi ne pitched blades, one or more of the teeth on each
side of the cut may need to be removed by grinding so
that the weld area of the blade is uniform and the teeth will
be uniformly spaced. See Figure 12, and refer to section
12.5 Blade grinding.
Clean blade ends which
will contact welder jaws
Grind off teeth

12.3 WELDING
1. Clean welder jaws and lower jaw inserts.
2. Carefully clean ends of blade which will contact
welder jaws. Remove any dirt, oil, scale and oxide.
3. Turn pressure knob (Figure 14) to “0” position (point-
ed downward).
NOTE: There will be some resistance when turning
knob.
4. Insert one end of blade into left clamp. Position back
edge of blade against back edge of left clamp. Then
position the end of the blade midway between left
and right clamps. Tighten left clamp.
5. Insert opposite end of blade into right clamp. Position
back edge of blade against back edge of right clamp.
Then butt the end of blade against the other end of
blade (the blade ends need to be in contact with
each other). Tighten right clamp.
!
The welder is designed for intermittent use. Repeat-
ed welding within a short period of time may cause
welder to overheat.
!
Any rust (oxide) on blade in vicinity of weld must be
ground off before blade can be welded.
