OVERVIEW

Restore Your Welder's Performance

Is your ESAB welder failing to strike an arc, or is the machine humming but not outputting power? The issue might be a worn-out contactor. The ESAB 0349313278 Contactor (Lovato BF80 42V) is the genuine replacement part you need to get your machine back up and running. The contactor acts as the heart of your welder's power system, acting like a heavy-duty switch that turns the welding current on and off every time you pull the trigger. Over time, the internal contacts can become pitted, burnt, or stuck due to the massive amounts of electricity they handle, leading to unreliable starts or a machine that won't turn off.

This replacement unit is manufactured by Lovato Electric, a brand renowned for durability and precision. It is the exact same component originally installed in your ESAB machine at the factory, ensuring a perfect fit and hassle-free installation. There is no need to modify mounting brackets or splice wires; simply disconnect the old unit and wire in the new one. The 42-volt coil is specifically matched to your welder's internal control circuitry, ensuring crisp, responsive switching every time you weld.

Investing in a high-quality OEM contactor protects the rest of your machine. A failing contactor can cause voltage spikes or excessive heat that may damage expensive printed circuit boards or transformers. By replacing your old contactor with this robust BF80 model, you ensure consistent arc starts, stable power delivery, and extended equipment life. Whether you are running a busy fabrication shop or a garage repair business, minimizing downtime is key. Keep your ESAB welder operating at peak efficiency with this authentic repair part.

FAQ

This contactor features a 42V AC coil (50/60Hz), which is a common control voltage for safety in industrial welding equipment.

Common signs include the machine not outputting power when the trigger is pulled, the contactor making a loud buzzing noise, or the machine staying 'on' (outputting current) even when the trigger is released (stuck contacts).

Yes, this is a genuine ESAB OEM part (SKU 0349313278). It is manufactured by Lovato Electric, which is the original supplier for the component in the machine.

BF80 is the model designation by Lovato, typically indicating the frame size and a rated operational current of approximately 80 Amps for AC-3 inductive loads.

No, you must verify that your machine requires a contactor with a 42V coil and similar amperage rating. Always check your machine's parts manual or the label on the existing contactor.

Replacing a contactor involves working with high-voltage internal components. It is highly recommended that installation be performed by a qualified electrician or certified welding machine repair technician.

The base BF80 unit typically includes the main power poles. Auxiliary contacts (for status feedback) are often modular add-ons. Please verify if your existing setup uses add-on blocks, as they may need to be transferred or purchased separately if not integrated.
