Figure 14. Blade ends in correct position for
welding.
Note: To ensure a good blade weld, it is critical that the blade ends are secured in the welding clamps evenly and with no overlap (see Figure 15).

8. Use the tables below to set the clamp pres- sure switch and the anneal strength (see
Figure 16).
• For T10499:

• For T10500:
Blade Width | Clamp | Anneal | |
Pressure | Strength | ||

High |
Note: As you rotate the clamp pressure switch, the left clamp will move and apply pressure toward the right. This pressure is necessary to maintain contact between the blade ends as the metal melts during the welding operation.
