💡 Key Repair & Operation Instructions:
- Matching Hardness: Deposited weld metal yields 30–34 HRC, perfectly matching pre-hardened P20 parent steel to eliminate boundary haloing during EDM and polishing.
- Parting Line Repair: Use short arc pulses to tightly control heat input, avoiding undercut or sink marks on precision parting surfaces.
