WL20 (EWLa-2) is a blue-tip 2% lanthanated tungsten for stable starts and broad AC or DC TIG use, including modern inverter machines.
Why Choose WL20
WL20 is the broad-use option in this range. Its 2% lanthanated composition supports reliable starting and a stable arc in both AC and DC TIG applications without the thorium used in WT20 electrodes.
