19918 - ESAB PT-17A Replacement Plasma Electrode - Pack of 2

Reliable Performance for PT-17A Systems

The ESAB 19918 Electrode is a critical component designed specifically for the PT-17 and PT-17A plasma cutting torches. In any plasma cutting operation, the electrode serves as the focal point for the electrical arc, transferring high-amperage current to the gas stream to create the plasma jet. Because it endures extreme thermal stress and electrical erosion, the quality of the electrode directly impacts the quality of the cut and the operational life of the torch. This product is manufactured to meet rigorous standards, ensuring compatibility and performance that professionals expect from ESAB equipment.

Constructed with a high-grade copper body, this electrode offers superior thermal conductivity. Efficient heat dissipation is vital in plasma cutting to prevent the consumable from overheating, which can lead to rapid failure or damage to the torch head itself. Embedded within the copper body is a hafnium insert, the active element that emits the electrons required to sustain the plasma arc. The hafnium is precisely centered to ensure a stable, focused arc, which results in cleaner cuts, narrower kerfs, and less dross buildup on the workpiece. This attention to material composition and manufacturing precision helps extend the service life of the consumable, reducing the frequency of changes.

Regular maintenance of plasma consumables is essential for cost-effective operation. A worn electrode can cause the arc to wander, leading to beveled cuts and poor edge quality. If an electrode is allowed to wear down until the hafnium pit is too deep, it can burn through to the copper, potentially destroying the nozzle and the torch head. By stocking the ESAB 19918 in this convenient 2-pack, operators can adhere to a proactive maintenance schedule, swapping out components before they fail and ensuring the plasma system operates at peak efficiency. Whether you are cutting mild steel, stainless, or aluminum, these electrodes provide the consistency needed for industrial fabrication.

This product is specifically engineered for the PT-17 series, a robust line of torches known for their durability in manual cutting applications. Using the correct electrode ensures that gas flow dynamics within the torch remain undisturbed, preserving the cooling capacity and the shape of the plasma arc. Trust in the 19918 electrode to deliver the power and precision required for your metal cutting tasks.
