CK LaYZr tungsten electrodes deliver exceptional arc stability and longevity for precision TIG welding applications. This 1/16″ diameterelectrode features a lanthanum-yttrium-zirconium oxide blend that provides superior arc initiation and maintains a stable welding arc across a wide amperage range.

Key Features

• 1/16″ (1.6mm) diameter— ideal for thin material welding and detailed work
• LaYZr composition— lanthanum-yttrium-zirconium oxide for enhanced performance
• Superior arc initiation— starts easily at low amperages
• Extended electrode life— reduces consumable costs and downtime
• Excellent arc stability— maintains consistent performance throughout use
• Low burn-off rate— minimizes tungsten contamination in welds

Welding Performance Guide

AC Welding (Aluminum):5-60 amps for 1/16″ diameter. LaYZr tungstens excel in AC applications, providing clean arc starts and stable performance on aluminum alloys. The oxide blend maintains ball tip formation while resisting tungsten spitting.

DC Welding (Steel/Stainless):5-80 amps for 1/16″ diameter. Grind to a sharp point for DCEN welding applications. The lanthanum content provides excellent electron emission properties, while yttrium and zirconium enhance arc stability and reduce tip erosion.

Tip Preparation:For DC welding, grind lengthwise to create a sharp point with the grinding marks running parallel to the electrode axis. For AC welding, allow the electrode to naturally form a ball tip during welding.

Ideal for precision welding applications including aerospace components, thin-wall tubing, and delicate fabrication work where arc control and minimal heat input are critical.
