Typical Applications
These contact tips excel in high-volume production welding, structural fabrication, pipe welding, and maintenance repair operations. The severe-duty rating makes them ideal for shops running extended shifts or high-amperage applications (250–350 A) where tip wear is accelerated. Replacement tips should be installed whenever arc quality degrades, wire burnback occurs, or feed problems develop.
