Tandem Arc Long Stick Out - Submerged Arc Welding

The combination of the Power Wave® AC/DC 1000® SD Inverter technology with the addition of an extension to the welding torch enables the long stick out process (LSO). 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.


Long Stick Out

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. Thanks to the “Joules” effect, the electrode is pre-heated and melts faster than it would, at the same amperage, with standard Stick Out.

Solution Benefits:

>> High quality welding results
>> Excellent bead appearance
>> Highest deposition rates
>> Deep penetration
>> Increased productivity

The long stick out process is the most productive of the single power source processes. With Tandem Arc AC LSO, over 196 hours can be saved per tonne of welding wire deposited compared to Single Arc DC+.

Power Wave AC/DC 1000 SD

Subarc Equipment

The Power Wave® AC/DC 1000SD Advanced Submerged Arc Welder leads the industy in SAW innovation and capabilities.

It delivers Waveform Control Technology® to submerged arc welding. Software-driven AC, DC positive or DC negative output allows the user to control the deposition rate and penetration. 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.

Today’s lean manufacturing environment demands accountability, constant monitoring and quality control. Lincoln Electric’s proprietary software makes it easy to ensure the highest quality and efficiency.
