Wire nesting issues and inconsistent weld quality with the Comparc S-512P CV aluminum MIG welding machine could be caused by:

- Incorrect drive roll size for the application.
- Worn or dirty drive rolls.
- Improper drive roll pressure.
- Faulty PC1 control board.

Each of these issues can disrupt smooth wire feeding, leading to nesting and poor weld quality.
