SPECIFIC INSTRUCTIONS & DETAILS
1. Fill passe 3 & 4 represent Fill1.
2. Fill passes 5, 6, 7 & 8 represent Fill2.
3. Fill1 or Fill2 application may be waived. However, this will be generally controlled by the BM thickness
and the user's decision.
4. The bead sequence shown in the drawing is recommended but not mandatory.
5. The number of beads may vary, depending upon bead thickness.
6. Amperage, voltage, and travel speed limits are mandatory due to heat input restrictions.
