OVERVIEW

Technical Overview of the ESAB 951491 Contactor

The ESAB 951491 is a robust 3-pole contactor designed specifically for the demanding electrical environments found within industrial welding equipment. As a critical component in the power regulation circuit, this contactor manages the high-current switching required to initiate and terminate the welding arc or power the main transformer. It is engineered to handle a continuous load of 90 Amps, making it suitable for medium to heavy-duty welding power sources.

This unit features a 115 VAC control coil, a standard voltage for many industrial control circuits, ensuring compatibility with a wide range of ESAB machines and potentially other equipment requiring similar specifications. The 3-pole design allows for the simultaneous switching of three phases, which is essential for three-phase power sources commonly used in industrial fabrication shops. The contacts are manufactured from high-grade materials to resist oxidation, pitting, and welding, ensuring a long service life even under frequent cycling.

Proper maintenance of the contactor is vital for machine performance. A failing contactor can lead to erratic arc starts, power loss, or even damage to other internal components. The ESAB 951491 provides a direct OEM fit, ensuring that mounting points and terminal connections align perfectly with the original equipment configuration, minimizing downtime during repairs.

FAQ

The ESAB 951491 contactor is rated for 90 Amps.

The control coil voltage is 115 VAC.

This is a 3-pole contactor, suitable for switching three phases.

Yes, this is a genuine replacement part intended for ESAB equipment.

Common signs include a loud buzzing or humming noise, the machine not outputting power, or the contactor sticking closed (machine stays live).

No, this contactor requires a 115 VAC control signal. Using it on a 24V circuit will not actuate the coil.

Typically, contactors are sold as the unit itself. You usually reuse existing mounting screws or hardware from the machine.

It is primarily used to switch the main power transformer or output in welding power sources.
