0558006028 - ESAB PT-36 Plasma Nozzle XR 2.8mm (.109) - 5 Pack

High-Precision ESAB PT-36 Consumables for Automated Cutting

The ESAB 0558006028 is a premium-grade XR series nozzle designed specifically for the PT-36 mechanized plasma torch, a core component of ESAB's advanced m3 Plasma systems. Engineered with a 2.8mm (.109 inch) orifice, this nozzle is calibrated for high-amperage cutting applications where deep penetration, speed, and edge quality are paramount. The "XR" designation indicates ESAB's Extended Life technology, which utilizes advanced copper alloys and internal geometry optimizations to withstand the intense thermal and kinetic energy of the plasma arc for longer durations than standard consumables.

In automated cutting environments, consistency is the critical metric. The 0558006028 nozzle is manufactured with strict adherence to concentricity tolerances. This ensures that the plasma arc remains perfectly centered within the gas stream, preventing "skewed" cuts and ensuring that parts come off the table with square edges and minimal dross. The 2.8mm orifice size is typically utilized for processing thicker sections of mild steel, stainless steel, or aluminum, depending on the specific gas combination (Oxygen, Nitrogen, or H35) employed by the controller. By maintaining a stable, constricted arc, this nozzle maximizes energy density, allowing for faster travel speeds without sacrificing cut fidelity.

Thermal management is another key aspect of the PT-36 nozzle design. The mass and shape of the nozzle are calculated to efficiently dissipate the heat generated during the pilot arc and main cutting phases. This efficient cooling prevents the orifice from becoming out-of-round prematurely, a common failure mode in lesser quality consumables. For industrial integrators and facility managers utilizing the m3 system, sticking to genuine ESAB consumables like the 0558006028 ensures that the power source and torch perform according to the manufacturer's published cut charts, maintaining process reliability and predictability.

This product is supplied in a pack of 5, facilitating inventory management for high-production shifts. Proper installation involves ensuring the nozzle is seated correctly within the retaining cap and that the swirl baffle and electrode are in good condition, as upstream wear can affect nozzle life. By choosing the ESAB XR series, operators invest in process stability, reducing the frequency of torch maintenance interventions and maximizing the uptime of their gantry or robotic cutting cells.
