993717 - ESAB 993717 Control Transformer 117V to 24V CT 200VA

Restore Power with the ESAB 993717 Replacement Transformer

When your welding operations grind to a halt due to a control circuit failure, the ESAB 993717 Transformer is the reliable solution to get you back up and running. This heavy-duty control transformer is specifically designed for ESAB welding machines, acting as the heartbeat of the control system. It converts the 117V internal line voltage down to a stable 24V Center Tapped output, which is essential for powering the machine's brain—including printed circuit boards, wire feed motors, and gas solenoids. A failing transformer can manifest as intermittent power issues, dim displays, or a completely dead machine, and swapping it out with this 200VA unit is often the fix.

Heavy-Duty Electrical Design

The 200VA capacity of this transformer is a key feature, offering significant headroom for powering multiple control components simultaneously. In welding applications, components like large contactors can draw significant current when engaging; the 200VA rating ensures that the voltage remains stable during these events, preventing logic resets or relay chatter. The Center Tapped (CT) configuration on the 24V secondary side adds flexibility, allowing the machine design to utilize different voltage potentials relative to the ground, which is common in sophisticated welding power source designs.

OEM Quality for Long-Term Performance

While generic transformers exist, they often lack the specific impedance and insulation characteristics of the ESAB 993717. This OEM part is tested to ensure it handles the thermal stresses of a welding environment, where ambient temperatures inside the case can rise significantly during long welds. The insulation varnish and core lamination are selected to prevent short circuits and reduce eddy current losses. By choosing the official ESAB part, you are protecting the downstream components of your welder from potential damage caused by incorrect voltages or poor regulation.

Maintenance and Repair

Replacing a transformer is a standard procedure for qualified repair technicians. The ESAB 993717 is designed to be a drop-in replacement for the original part, matching the physical dimensions and wire termination points of the factory-installed unit. This minimizes downtime and eliminates the guesswork associated with universal parts. Keep your shop productive and your equipment safe by insisting on genuine ESAB replacement parts for all your maintenance needs.
