A.T.S. is a qualified supplier of welding equipment for drawn arc welding and for short cycle welding studs, a type of welding most required in carpentry work.

The best-known drawn arc welding is the drawn arc welding with ceramic ferrule where an electric arc is fired between the stud and the component on which it is to be welded, obtaining in this way a complete fusion between the two, the ceramic ferrule protects the fusion from oxidation and slows the cooling, then it is crushed.

Another drawn arc stud welding or internally threaded studs welding is the gas protected arc welding, used for diameters up to 12mm where it is possible to weld threaded studs or welding studs such as shear connectors without the ceramic ferrule, protecting the welding with inert gas.

Another type of drawn arc welding is the short cycle stud welding, a welding process that involves the use of an electric arc to melt and join materials such as thin metal sheets or to work in difficult positions, obtaining a greater seal than the capacitor discharge stud welding.
In this type of short cycle stud welding are used the welding studs PS type up tp M8, internally threaded studs IS type and other welding studs included in the catalog.
