0349313279 - ESAB 0349313279 Replacement Contactor NC1 9511 42V Coil

Genuine ESAB Electrical Component

The ESAB 0349313279 Contactor (Model NC1 9511) is a critical electrical component designed for specific ESAB welding power sources. As a genuine OEM part, it guarantees precise fitment and adherence to the original engineering specifications of your equipment. This contactor features a 42V coil and is rated for operation at both 50Hz and 60Hz frequencies, making it a versatile component for various regional power standards supported by ESAB machinery.

Contactors are the heart of the power switching mechanism in welding machines. They are responsible for making and breaking the high-current circuit that delivers power to the welding arc. Over time, the internal contacts can wear down due to arcing and mechanical cycling. Replacing a worn contactor with this genuine ESAB unit ensures that your machine maintains consistent arc initiation and power stability. Using non-OEM electrical parts can lead to control circuit failures or improper voltage regulation, potentially damaging sensitive internal electronics.

This unit is built to withstand the rigorous demands of industrial environments, offering high durability against thermal stress and vibration. Whether you are performing preventative maintenance or repairing a breakdown, the ESAB 0349313279 provides the reliability professional technicians demand.
