950368 - ESAB 2-Pole 40 Amp Replacement Contactor 110V Coil

Get Your Welder Back to Work

Is your welding machine humming but not striking an arc? Or perhaps you pull the trigger and hear a loud click, but nothing happens? These are classic symptoms of a failing contactor. The ESAB 950368 Contactor is the replacement part you need to restore your machine's power switching capabilities. As the "heart" of your welder's power delivery system, the contactor takes the signal from your trigger and closes the high-voltage circuit to the transformer.

Over time, the internal contact points of a contactor can become pitted, carbonized, or even welded shut due to the intense electrical arcing that occurs during switching. When this happens, your machine may lose power output, stick in the "on" position, or fail to start altogether. Replacing a worn contactor is a standard maintenance procedure that can breathe new life into an older machine and prevent damage to other expensive components.

This specific unit is a 2-Pole, 40 Amp contactor with a 110V AC coil. It is designed to handle the rigorous demands of welding, where rapid on-off cycling is common. The 40-amp rating ensures it can carry the necessary current without overheating, while the 110V coil matches the control voltage of many standard ESAB machines. Installation is straightforward for those familiar with machine repair, featuring secure screw terminals for your wire connections.

Don't let a faulty $50 part keep your expensive equipment gathering dust. By using genuine or spec-matched replacement parts like the ESAB 950368, you ensure that your welder operates safely and reliably. Verify your old part number or check your machine's manual to confirm compatibility, and get back to laying beads with confidence.
