Spot welding machine

possible, but difficult, becasue the machine use capacitor discharge at instant.

It's done all the time. The welds can be made in series or parallel. Your welding equipment must be able to supply enough power to make all the welds. The Welding Handbook or your supplier can show you how to do it.

I set it up at the yard every day. Power is the key, also gas setting to avoid porosity, and like any application cleanliness.The question to me is if your employees mess something up. You have accomplished twice the waste and saved minimal time.

What is a sble??

Multi spot welding is possible from one machine, Items to consider are large power supply to machine and capability of machine to pass large amounts of power into welds,also current balancing at weld interface, contact pressure balancing. welding head design to achieve these requirements, electronic timing circuit and variable power selection.

Number of individual spots depends on your machine power, if you ere requiring something like a seam welder this can be accomplished with rotating discs and pulsed power.
