0349483722 - ESAB Thermal Overload Switch S01.130.05

Genuine ESAB Temperature Switch 0349483722

The ESAB 0349483722 Temperature Switch (marked S01.130.05) is a critical replacement component designed for specific ESAB welding power sources. As an Original Equipment Manufacturer (OEM) part, it guarantees the precise fit, form, and function required to maintain the safety and reliability of your industrial equipment. In the world of high-amperage welding, thermal management is paramount. This switch acts as a safety sentinel, monitoring the internal temperature of your machine's vital components—such as the transformer, rectifier, or inverter block—and interrupting the circuit if temperatures exceed safe operating limits.

Using non-OEM or generic thermal switches can lead to improper activation temperatures, potentially causing nuisance tripping (stopping work when the machine isn't actually overheating) or, worse, failing to trip when critical temperatures are reached. The S01.130.05 marking typically indicates a specific calibration point (likely around 130°C, though verification via service manual is recommended) tailored to the thermal dynamics of ESAB machines. By installing this genuine part, you ensure that your welding fleet remains compliant with factory specifications and safety standards.

Maintenance personnel and technicians understand that a small component like a temperature switch plays a massive role in asset protection. A failed switch can leave a machine vulnerable to catastrophic burnout or render it inoperable if the switch fails in the 'open' position. This replacement part is built to withstand the harsh environments typical of fabrication shops, including exposure to vibration, dust, and thermal cycling. Whether you are performing preventative maintenance or an emergency repair, the ESAB 0349483722 is the correct choice for restoring your equipment's thermal defense system.
