Resistance welding machines, categorized into five main types: AC, DC, capacitor discharge, inverter, and transistor. Each type offers distinct advantages, disadvantages, and value, making the selection process crucial. The most effective approach is to choose a welding machine based on specific needs, the suitability for your workpieces, and experimental results. The common type of resistance welders includes spot welding, projection welding, seam welding, butt welding and flash welding. 

It's important to note that resistance welders typically use a filler-free welding method, unlike CO2 and Argon welders which require filler material. The electrode material, shape, and design are particularly important for weld quality, as they are consumable components. Utilizing alloy copper electrodes with low-voltage and high-current of resistance welders allow the metal to reach high temperatures instantly, fulfilling the welding requirements. We also offer micro and precision models for smaller workpieces that require high welding precision.

By communicating with customers about their welding needs, we, Yuh Shin propose suitable solutions and machine models to solve the welding needs of workpieces. Spot welders are widely used in the automotive industry for sheet metal and various interior components/parts whether they are large or small.

Other key applications include Automotive Body And Chassis, Electrical and Electronics, Aerospace, Bicycle, Household Appliances, Sheet Metal Parts Manufacturing, Metal Furniture And Construction, Kitchen Furniture And Appliances, Battery Packs, Wire Mesh Products, Wire Harness Assembly And other various sheet metal fabrication industries.

Resistance spot welding is a thermo-electric joining process that welds two or more thin sheets of metal together without filler material. This is achieved by using copper alloy electrodes to apply pressure and pass a high electrical current through the sheets. This fast and low-voltage process is commonly used in related sheet metal manufacturing industries for overlap joints, especially in the automotive field.
