10 amps. More than five times the cross-section.
Why pure nickel needs a much larger cable cross-section than copper—and how ambient temperature, heat dissipation and termination determine a safe design.

Manufacturer or dealer? How you can recognize the real manufacturer
Seven touchstones for buyers: response time, custom-made products, design, zone heating, factory tour and verifiable references - who really manufactures and who just buys.

The magnet held. The measurement did not.
A surface sensor on an induction-heated extruder read 21 °C too low. Only a design adapted to the application and heat path matched the reference value.

Vibration loosens connectors and terminals on heating elements
Error pattern from practice: Vibration loosens the contact, the contact resistance increases, the terminal carbonizes. This is how you design the connection and element to be vibration-proof.
