MCCB Highlights

Advantages and highlights of welding process equipment for MCCB Electronic type hardware parts

Side heating resistance welding process: The silver spot welding transfers heat from copper heating to silver spot welding. The silver spot has no electrical corrosion damage, which does not cause the silver spot surface to fade and become soft. It retains the original state of the silver spot. The contact has no damage, and the welding consistency is good, which increases the mechanical life and electrical life of the contact point by 15%.

Infrared temperature control technology: Used to precisely control the welding parameters, which ensures the welding quality and greatly improves the service life of the product by 50%.

Frequently Asked Questions (FAQ)

QWhat are the main advantages of this MCCB welding process equipment?

The equipment utilizes a side heating resistance welding process and infrared temperature control technology. These features prevent electrical corrosion on silver spots and precisely control welding parameters to extend the product's overall service life.

QHow does the side heating resistance welding process protect the silver spot?

By transferring heat from copper heating to the silver spot welding, it prevents electrical corrosion damage, color fading, and softening, thereby retaining the original state and integrity of the silver spot.

QBy how much does the new welding process increase contact point life?

Due to damage-free contact welding and excellent welding consistency, the mechanical and electrical life of the contact point is increased by 15%.

QWhat role does infrared temperature control play in the welding process?

Infrared temperature control technology precisely monitors and adjusts the welding parameters in real-time, ensuring stable welding quality and improving the product's service life by 50%.

QIs this equipment suitable for electronic type MCCB hardware parts?

Yes, this welding process equipment is specifically optimized for MCCB electronic type hardware parts, ensuring high precision and durability for delicate electronic components.

QWhat prevents the silver spot surface from fading and becoming soft during welding?

The side heating resistance welding process shifts the heat source from direct copper heating to silver spot welding dynamically. This prevents electrical corrosion, so the silver spot remains hard and keeps its original color.
