Unfortunately, tack welds and similarly unfavourable conditions on the workpiece are part and parcel of every welder. At least, welders who are fortunate enough to work with Lorch’s new S-series will not have to deal with such nuisances. Where other pulse arcs experience the occasional stutter, our new S-series with SpeedPulse XT will never skip a beat and complete any task without a hitch.
This is a difference you can actually hear. Aside from ensuring that spatter is kept at a minimum, the patented control technology can also completely eliminate the otherwise typical and sometimes abrupt and annoying changes in frequency. The result is a pleasant sound with a constant frequency combined with a first-class seam and a flawless welding result that stands up to any inspection.
