Dual Pulse Spot Welding

Some resistance spot welding power supplies employ a dual pulse spot welding feature which allows the use of two pulses to make a weld. The first pulse is generally used to displace surface oxides and plating, and the second pulse welds the base materials. This feature also reduces spitting.
