31134 - ESAB 31134 Control Transformer 1200VA 60Hz Replacement Part

Get Your ESAB Welder Back to Work

When your welding machine goes down, production stops, and time is money. If your ESAB power source is powering up at the breaker but showing no signs of life on the front panel—no lights, no fan, and no clicking from the contactors—you might be dealing with a blown control transformer. The ESAB 31134 Control Transformer is the genuine replacement part you need to fix the issue and get back to burning rod. This isn't a generic off-the-shelf electrical part; it is the specific 1200VA, 60Hz unit designed to fit and function perfectly inside your ESAB equipment.

Control transformers are the unsung heroes of your welder. They take the heavy input power coming from the wall and convert it into the "brain power" that runs the switches, gas valves, and computer boards. Because this unit is rated for a hefty 1200 Volt-Amperes (VA), it provides strong, stable power that ensures your contactors pull in tight and your wire feeder runs smoothly. A weak or failing transformer can cause intermittent issues, like gas solenoids fluttering or the arc cutting out unexpectedly. Swapping it out with this fresh OEM unit eliminates those gremlins.

Installation is straightforward for qualified repair technicians, as this part is designed with the correct mounting footprint and terminal connections for the original machine assembly. Don't risk your expensive control boards by trying to retrofit a generic transformer that might have the wrong voltage tap or insufficient power rating. Stick with the ESAB 31134 to ensure your machine runs exactly how the factory intended, keeping your welds high-quality and your shop productive.
