1.6MM lanthanated tig tungstens welding electrodes X10
10 Pack 1.6mm Lanthanated Tig Tungstens
10 pack of Lanthanated tungsten electrodes - gold tip. These are a safe substitute for thorium tungstens which are mildly radioactive.
Lanthanated tungsten electrodes (AWS classification EWLa-1.5) contain a minimum of 97.80 percent tungsten and 1.30 percent to 1.70 percent lanthanum, or lanthana, and are known as 1.5 percent lanthanated. These electrodes have excellent arc starting, a low burnoff rate, good arc stability, and excellent reignition characteristics many of the same advantages as ceriated electrodes.
Lanthanated electrodes also share the conductivity characteristics of 2 percent thoriated tungsten. In some cases, 1.5 percent lanthanated can replace 2 percent thoriated without having to make significant welding program changes.
Lanthanated tungsten electrodes are ideal multitype tungsten. They work well on AC or DC electrode negative with a pointed end, or they can be balled for use with AC sine wave power sources.
Lanthanated tungsten maintains a sharpened point well, which is an advantage for welding steel, stainless steel on DC or AC from square wave power sources and also ideal for the modern inverter type tigs where a pointed electrode can be used in AC for welding aluminium
These electrodes are very suitable for AC welding and, like ceriated electrodes, allow the arc to be started and maintained at lower voltages. Compared with pure tungsten, the addition of 1.5 percent lanthana increases the maximum current-carrying capacity by approximately 50 percent for a given electrode size.
