34359 - ESAB PT-15XL/19XL Replacement Pilot Arc Lead 17ft

Reliable Arc Initiation for Heavy-Duty Plasma Systems

The ESAB 34359 is a specialized Pilot Arc Cable designed exclusively for the PT-15XL and PT-19XL series of plasma cutting torches. In high-amperage mechanized plasma cutting, the integrity of the pilot arc circuit is paramount for consistent performance. This cable serves as the dedicated conductor for the pilot current, which ionizes the gas and creates the plasma path required to transfer the main cutting arc to the workpiece. Without a functioning pilot arc cable, the system cannot initiate the cut without physical contact, which is often impossible or impractical in automated setups.

Measuring 17 feet in length, this cable is engineered to match the standard lead packages of compatible ESAB power sources and torch assemblies. It features high-grade copper stranding optimized to carry the pilot current with minimal voltage drop, ensuring that the arc initiates instantly when triggered. The insulation material is selected for its dielectric strength and resistance to the harsh environment of industrial metal fabrication, including exposure to heat, sparks, and cutting fluids.

Over time, the constant flexing of torch leads in gantry systems or manual manipulation can cause internal fatigue in electrical cables. A compromised pilot arc cable often manifests as intermittent starting issues or a complete failure to ignite the pilot flame. Replacing a worn or damaged cable with this genuine ESAB 34359 part restores the torch to factory specifications. It is a critical maintenance component for facilities running older but robust ESAB plasma systems like the PCM-150 or ESP series equipped with PT-15XL or PT-19XL torches.

Installation involves routing the cable through the existing torch lead sheath and terminating it correctly at the torch head and the power supply connection block. Because this component carries electrical current, proper installation is vital for safety and equipment longevity. By choosing the OEM replacement, operators ensure that the connectors and wire gauge are exactly suited for the thermal and electrical loads defined by ESAB's engineering standards.
