Using the Blade Welder
Blade Shear and Blade Preparation
1.
The blade should be cut to the longest length
that machine will accept.
2.
Put the handle in the upright position.
3.
Place the blade against the back of the square
cutting guide of the shear.
4.
Bring the handle down firmly to cut blade.
5.
Use the blade grinder to assure the blade ends
are flat, square, and smooth.
6.
With fine pitched blades, one or more teeth from
each side will have to be removed by grinding so
that the cross section of the weld area is
uniform.
Welder Preparation
1.
Clean the welder jaws and the lowerjaw
inserts.
Welding
1.
Turn pressure switch (A, Fig. 11) to the zero
position.
2.
Join blade ends together and locateunion inthe
center between two electrodes.
3.
Set pressure switch (A, Fig. 11) to blade width
according to the scale.
4.
Press weld button (B, Fig. 11). Do not release
until the weld has been completed.
