OVERVIEW

Restore Your Predator's Power Generation

The Thermal Arc 11-3731 Stator is a critical replacement component designed specifically for the Thermal Arc Predator series of engine-driven welders. As the stationary component of your welder's generator system, the stator is responsible for converting the mechanical energy from the engine into the electrical energy needed for welding and powering auxiliary tools. Over time, stators can degrade due to heat, vibration, moisture, or electrical overload, leading to a loss of output or complete machine failure. This genuine OEM part ensures that your equipment is brought back to its original factory specifications.

When a stator fails, it often manifests as a complete loss of welding power or auxiliary voltage, or sometimes as low voltage output that cannot sustain a stable arc. Installing this direct-fit replacement eliminates the guesswork associated with rewinding services or aftermarket generic parts. The 11-3731 is engineered with precise copper windings and high-grade core laminations to match the Predator's power curve perfectly. This ensures that your machine delivers the smooth, consistent arc characteristics that Thermal Arc is known for, while also providing safe and regulated power to the 120V/240V outlets.

Durability is key in engine-driven environments. This stator features heavy-duty insulation and varnish dipping to protect the sensitive copper windings from the harsh realities of the job site, including dust ingress, humidity, and the constant vibration of the engine. Whether you are repairing a machine for a rental fleet or fixing your primary rig, using the correct part is essential for longevity. Trust the Thermal Arc 11-3731 to get your Predator back up and running efficiently, minimizing downtime and maximizing productivity.

Note: Installation of generator components involves high voltage and mechanical disassembly. We recommend installation by a qualified technician to ensure safety and proper calibration.

FAQ

This stator is designed specifically for the Thermal Arc Predator series of engine-driven welders.

Common symptoms include zero welding output, no auxiliary power, low voltage output, or a burning smell coming from the generator end.

Yes, this is a genuine OEM replacement part, ensuring proper fit and performance specifications.

Yes, in the Predator design, the stator windings are responsible for generating the AC power that is used for both the welding output (after rectification) and the AC auxiliary outlets.

Replacing a stator requires significant disassembly of the generator end and involves high-voltage components. It is highly recommended that a qualified technician perform the installation.

No, the stator (stationary part) and rotor (rotating part) are sold separately. This item is the stator assembly only.

A technician typically performs resistance checks on the windings using an ohmmeter and checks for shorts to ground (the iron core) using a megohmmeter.

Yes, the windings are dipped in high-grade insulating varnish to protect against moisture, vibration, and abrasion.
