Product identification

Check the cutting-head or welding-head brand and exact model.
Compare the part number, dimensions and markings with the currently installed part.
If any identity field is missing or conflicting, request verification before ordering.

No. Similar appearance or dimensions alone do not prove compatibility. Confirm the exact model, part number and listed specifications.

Provide the equipment or head model, current part marking, dimensions and a clear photo when available.
