Resistance welder, is a device that weld metal materials together using the principle of resistance heating. The working principle Is By applying pressure and passing an electric current through the contact points of the workpieces, the heat generated by the workpieces' resistance melts the metal, which then cools to form a strong spot or seam welding. This welding method is widely used in the automotive, home appliance, sheet metal fabrication, electronic component, metal furniture and construction, battery packs, wire mesh products…etc industries due to its speed, low cost, and ease of automation.

The Advantages Of Resistance Welding?
1)Cost-effective: It does not require external filler materials like welding rods or flux, which reduces costs. The equipment is also relatively inexpensive to maintain.

2)High speed and automation: The process is very fast and can be easily automated, making it ideal for high-volume production, such as in the automotive industry.

3)Consistent and reliable: Automation ensures consistent welds every time by using pre-programmed parameters for current, pressure, and time, which reduces defects.

4)Clean and environmentally friendly: The process generates very little smoke, fumes, or slag, creating a cleaner working environment.
Versatile: It can join a wide range of materials, including different types of metal sheets, and is suitable for creating airtight and watertight seals.

5)Lower labor and safety benefits: Automation reduces the need for constant manual intervention, and the use of low voltage makes the process safer for operators by minimizing exposure to sparks, heat, and electrical hazards.
