Frequently Asked Questions
Q
What wire types are compatible with this tension pay-off stand?
The stand supports both round wire (diameter 0.5 mm–50 mm), including enameled copper and enameled aluminum wire, and flat wire (cross-section 5 mm×10 mm to 20 mm×50 mm), including paper-insulated flat wire and bare flat copper wire. This broad compatibility makes it suitable for a wide range of transformer coil winding applications.
Q
How accurate is the tension control system?
