Material: Molybdenum, Molybdenum alloys 

Pulse hot soldering head 

This product is used in pulse welding machine, It is the pulse welding heating body, It by thermocouple transmission pulse electric current to heat, make the joint part is in close contact condition, with no heat affected around the device. 

Usage: 

Mainly used for welding thin coaxial I-PEX, FPC, FFC and PCB Soldering, LCD, and the ACF of TCP connections, HDMI, MINI USB Connector welding etc. 

Advantage: 

Using the welding does not happen in a virtual welding phenomenon, and Can achieve a multipoint welding, can need not consider the operating Skills of personnel, to ensure the quality of welding. And Temperature, can live in the present, to ensure the welding quality, Especially suitable for high precision welding of high-end products. 

Welding head classification: 

1. Resistance Welding Heads 

2. Spot Welding Heads, 

3. Butt Welding Head, 

4. Hot Bar Reflow Soldering Heads 

5. Ultrasonic Welding Machine Welding Head 

We can according to customers required to provide all kinds of welding machine welding head. 

The principle of spot welding head: 

When the current moment, will produce electric spark in the electrode tips, and insulating paint part of the contact with the electrode tip was burnt, other insulating varnish to flinch at both ends, Then metal wire is bare. Due to the continuing effect of the welding pressure, drives a large amount of current to flow into the bare metal wire and metal base, electrical energy is converted into heat energy, succeed except paint and welding are in the same pulse. 

The design of spot welding head 

To ensure that the welding process is stable and reliable, ensure the service life to spot welding head. Because different welding materials, solder joint is not the same, the Welding energy is different, the required welding head design is different, General welding head is divided into three parts, they are electrical parts, transition sections parts and discharge parts. 

Note: Document prices and pictures are for reference only, We will according to customers drawings or samples of spot welding head for quotation.
