How do I know when to replace the induction coil or magnetic rods?

If you notice abnormal welding current, dark weld seams, or cracking, check for damaged or worn coils and ferrite cores.

Can slitting blades be resharpened?

Yes, they can be resharpened several times, but make sure thickness remains within tolerance to maintain precise clearance.

Do forming rolls require readjustment after replacement?

Yes, roller alignment and forming passes should be reset. Save parameter presets for each tube size to streamline changeovers.

Usage Tips & Spare Parts Management

1. Establish a minimum stock level for key items like magnetic rods, blades, seals, and coils.

2. Keep at least 1–2 full cycles of consumables ready for production use.

3. Clean and mark tools like rollers and blades after use for easy reassembly.

4. Inspect high-temperature parts like impeders and coils once per shift, replacing any cracked or deformed components promptly.

5. Consider a long-term supply agreement for parts to benefit from faster delivery and better pricing
