The LSO relates to a physical principle which, by pre-heating the wire, improves the fusion of the filler metal and increases the deposit rate without changing the welding current or the travel speed. In submerged arc welding, Stick Out, is the distance between the contact tip and the work piece. This distance can be increased using dedicated extensions of various lengths to obtain what is known as Long Stick Out LSO.
The wire electrical resistance increases with its length. The long stick out process is the most productive of the single power source processes. The advantage over conventional power sources is higher deposition rates without an increase in heat input, increased weld speeds, improved mechanical properties, lower electrical energy consumption, and easy set up and controls in a single or multi-arc applications.
