2118703 - ESAB PT-600 135A Plasma Nozzle

Precision Engineering for Heavy-Duty Plasma Cutting

The ESAB 2118703 is a high-performance 135 Amp nozzle designed exclusively for the PT-600 plasma cutting torch. In the realm of automated and mechanized plasma cutting, the nozzle serves as a critical component in defining the shape, density, and stability of the plasma arc. By constricting the gas flow and focusing the electrical energy, this nozzle enables the PT-600 system to deliver deep, clean cuts through conductive metals such as carbon steel, stainless steel, and aluminum.

Manufactured to ESAB's exacting OEM standards, this nozzle features a precision-drilled orifice that maintains a consistent diameter, which is essential for achieving square edges and minimizing kerf width. The 135A rating indicates its suitability for heavy-plate fabrication where high energy density is required to maintain cutting speeds without sacrificing quality. Using genuine ESAB consumables like the 2118703 ensures that the coolant flow within the torch head properly dissipates heat from the nozzle, preventing premature failure and extending the duty cycle of the consumable stack.

Operators of the PT-600 system rely on the geometric accuracy of the nozzle to maintain tolerance in CNC cutting operations. A worn or non-genuine nozzle can lead to arc wandering, excessive dross formation, and beveled edges, ultimately increasing secondary processing costs. This nozzle is engineered to withstand the thermal shock and erosion associated with high-amperage piercing and cutting, providing a reliable service life in demanding industrial environments.

Integration with the PT-600 torch involves a straightforward replacement process. It is recommended to inspect the nozzle regularly for signs of orifice ovality or external damage. Pairing this nozzle with the correct electrode and swirl ring is vital for maintaining the vortex gas flow that protects the nozzle bore and stabilizes the arc. Trust in ESAB's legacy of welding and cutting innovation to keep your production lines running efficiently.
