OVERVIEW

Restore Precision with the ESAB Pilot Arc Resistor Kit

The ESAB 35737 Pilot Arc Resistor Kit is a critical internal component designed to maintain the operational integrity of your ESAB plasma cutting system. In plasma cutting, the pilot arc is the initial spark that ionizes the air gap between the torch and the workpiece, creating the conductive path necessary for the main cutting arc to transfer. This resistor kit plays a vital role in regulating the current during this non-transferred arc phase, preventing current spikes that could damage the torch consumables or the power source itself.

Over time, the high-stress electrical environment inside a plasma cutter can degrade resistive components. A failing pilot arc resistor often manifests as difficult arc starting, an unstable pilot flame, or a complete failure to initiate the arc. By installing this genuine ESAB replacement, you ensure that your machine meets the original factory specifications for resistance and power handling. This is not a generic aftermarket part; it is engineered specifically for the thermal and electrical demands of ESAB power sources.

Professional repair technicians understand that using OEM parts is essential for safety and longevity. The ESAB 35737 kit is built to withstand the rapid thermal cycling inherent in industrial cutting environments. Whether you are troubleshooting an older machine or performing preventative maintenance on a production unit, this resistor kit provides the reliability you expect from the ESAB brand.

Key Benefits of Genuine ESAB Parts

  • Exact Electrical Match: Ensures the pilot arc current is limited to safe levels, protecting the torch tip and electrode.
  • Durability: Constructed from high-quality materials to resist vibration and heat buildup within the machine chassis.
  • Safety: Maintains the designed safety margins of the power source's high-voltage starting circuit.

Don't let a small electrical component halt your fabrication production. The ESAB 35737 Pilot Arc Resistor Kit is the definitive solution for resolving pilot arc circuit faults, getting your equipment back online with minimal downtime.

FAQ

The pilot arc resistor limits the current flowing through the pilot arc circuit before the arc transfers to the workpiece, protecting the torch and power source.

Symptoms often include the machine failing to establish a pilot arc when the trigger is pulled, or the pilot arc being weak and sputtering.

Yes, the ESAB 35737 is a genuine OEM replacement kit manufactured by ESAB.

Installation requires opening the power source chassis and working with electrical components. It is recommended for qualified repair technicians familiar with high-voltage safety.

No, it is specific to certain models. Please check your machine's parts manual or contact support with your serial number to confirm compatibility.

The kit typically includes the resistor assembly and any necessary mounting hardware required for the specific repair.

If the pilot arc establishes but fails to transfer, the issue might be the work clamp or material surface. This resistor primarily addresses the creation and stability of the pilot arc itself.

It is located inside the main power source cabinet, usually near the high-frequency or output rectification circuit board.
