Practical tips for best results:
- Always confirm the terminal and wire gauge (10-22 AWG) before crimping to ensure a proper fit.
- Test a sample crimp on a sacrificial terminal if you’re dealing with insulation thickness variations.
- Keep the crimping dies clean and lightly oiled at the pivot to maintain smooth operation and longevity.
