Images are for illustration purposes only. E&OE Overview Spot welding (also known as resistance spot welding) is a resistance welding process. This welding process is used primarily for welding two or more metal sheets together by applying pressure and heat from an electric current to the weld area. It works by contacting copper alloy electrodes to the sheet surfaces, whereby pressure and electric current are applied and heat is generated by the passage of current through resistive materials such as low carbon steels. Features The high frequency capacitor has low internal resistance and can withstand high temperatures of 105℃. The two-sided outlet is convenient for spot welding, and it is marked in Chinese, and it is not easy to connect wrongly. Super thick red copper tube, 10AWG wire, aluminum oxide copper spot welding needle, to ensure the over-current capability and durability, and greatly improve the spot welding efficiency. Pure copper conducts heat conduction, greatly improving the efficiency of spot welding.
