PowerWeld CER18-EA 1/8″ x 7″ 2% Ceriated Grey Tungsten Electrode (EWCe-2)

The PowerWeld CER18 1/8″ x 7″ 2% ceriated grey tungsten electrode is designed for higher-amperage TIG welding on thicker material where a steady arc and reliable starts matter. With its 1/8″ diameter, this tungsten provides strong current-carrying capacity for plate, structural components, and heavy weldments while still giving good puddle control. Classified as EWCe-2, it uses a 2% cerium blend that supports easy arc starting, improved arc stability, and a reduced rate of vaporization or burn-off compared with pure tungsten. Welders can strike the arc confidently, run longer passes, and keep a consistent point shape over more weld time.

The CER18 performs well on both DC and AC inverter TIG machines, either polarity. It is suitable for carbon steel, stainless steel, nickel alloy, titanium, and aluminum, making it a practical choice for mixed-metal shops that run heavier TIG work. The standard 7″ (175 mm) length fits common TIG torches and bench or hand-held tungsten grinders, while the grey tip color coding clearly identifies it as 2% ceriated tungsten in racks and storage tubes. Sold individually, this electrode can be purchased one at a time or ordered in groups of (10) pieces to build a full PowerWeld pack for fabrication bays, maintenance crews, and welding programs.

In fabrication bays, structural shops, and industrial plants, the PowerWeld CER18 gives welders a 1/8″ tungsten that balances current capacity with consistent arc control. Crews can run DC for carbon steel and stainless jobs that require deeper penetration, then switch to AC inverter settings for heavier aluminum or mixed-metal work using the same electrode. The smooth starts and steady arc that come with EWCe-2 chemistry help technicians manage the puddle on groove welds, fillet welds, and buildup passes where weld quality is critical.

Maintenance teams and advanced students value the reduced burn-off rate of ceriated tungsten, especially on long welds and multi-pass joints. Less vaporization at the tip means the sharpened point stays consistent for more arc time, so welders spend fewer breaks at the grinder and maintain a more uniform bead from root to cap. For shops that want a reliable, higher-amperage TIG welding tungsten that still works across a range of alloys and polarities, the CER18 is a practical, work-focused option.

Why Customers Choose the PowerWeld 1/8″ x 7″ 2% Ceriated Grey Tungsten Electrode

Welders pick the PowerWeld CER18 when they want a 1/8″ tungsten that can handle higher-amp TIG work on multiple alloys without sacrificing control. The EWCe-2 formulation delivers easy starts and a stable arc cone on DC for carbon steel and stainless, while also performing well on AC inverters for aluminum and other non-ferrous materials. This flexibility lets many shops standardize on a single higher-capacity electrode size for a large portion of their TIG welding tasks.

The reduced burn-off rate is another key reason for its popularity. On long structural welds and multi-pass repairs, the point stays sharper for more arc time, which keeps the puddle shape and penetration more consistent and cuts down on grinding breaks. For heavy fabrication, equipment building, and advanced TIG training where higher amperage is common, the PowerWeld CER18 offers dependable performance in a familiar 1/8″ x 7″ format.
