Welding
it:, CAUTION
The welder is designed for intermittent use.
Repeated welding within a short period of time
may cause the welder to overheat.
1. Turn pressure switch (A, Figure 14) to the zero
position.
2. Join blade ends together and locate union inthe
center between two electrodes. Lockblade in
position by liftinglevers (C and D,Fig. 14).
3. Set pressure switch (A)to blade widthaccording
to the scale.
4. Press weld button (8). Do not release untilthe
weld has been completed.
Annealing
1. Release the welded blade and clamp itagain
between the front edge of the twojaws.
2. Annealing procedure willdepend on blade type:
Carbon Steel Blades
1. Press and jog the annealing switch button until
the weld is a "dullcherry"to "cherryred" color.
2. Allowthe blade to cool slowlybydecreasing the
jogg~ngfrequency.
Carbon
Steel Hard Back Blades
1. Heat the blade slowlyuntilthe weld becomes a
deep blue color.
2. Continue to heat byjoggingthe anneal button
untilthe widthof the blue color is one-half the
length of the band exposed between the jaws.
3.
Do not overheat or the temper ofthe band will
be damaged. Caution - Do not heat beyond
the "blue"stage. Ifthe band begins to show
any red color, itis too hot. Coolquicklyby
releasing the anneal button.
