3. Loosen the welding clamps by pulling the
lock levers down.
4. Position the back of one blade end evenly
against the back of the welding clamp so that
the end is midway between the two clamps,
then rotate the lock lever all the way up to
hold the blade end in place (see
Figure 35).
Figure 35. Blade end properly position in
welding clamp and locked in place.

5. Set the clamping pressure dial (see Figure
36) to "0".
Note: As the blade material melts to form the
weld, pressure is applied to the joint by the
welding clamps. The correct amount of pres
-
sure is set with the clamping pressure dial in
a later step.
6. Place the other blade end in the opposite
welding clamp and position it so that it evenly
butts up against the opposing blade end,
then
lock it in place by rotating the lock lever all the
way up, as shown in
Figure 36.
Note: For a good blade weld, it is critical that
the blade ends evenly butt up against each
other.
7. Use the chart in Figure 37 and set the correct
clamping pressure setting for the blade.
Burning sparks from the blade welding oper-
ation may be thrown in all directions and
could cause serious personal injury or fire.
When using the blade welder, always protect
yourself from the flying sparks and have fire
extinguishing equipment readily available.
DO NOT weld near flammables.
8. Press and release—DO NOT hold—the weld-
ing button.
Note: There is a limit switch that senses the
electrical resistance between the blade ends.
If there is a adequate amount of welded mate
-
rial, the limit switch will not allow the welding
button to activate the operation again.
