0000829679 - ESAB Control Transformer 380-480V to 230V 150VA

Precise Voltage Control for Industrial Welding Equipment

The ESAB Transformer (SKU: 0000829679) is a critical component designed for the internal power management of industrial welding machines. As a control transformer, its primary function is to step down high-voltage mains input—ranging from 380V to 480V—to a stable and usable 230V output. This 230V supply is essential for powering the auxiliary circuits of the welding power source, including cooling fans, control boards (PCBs), gas solenoids, and wire feed motors. By isolating these sensitive components from the main power line, the transformer ensures consistent operation and protects the control logic from line noise and spikes.

Rated at 150 Watts (150VA), this transformer provides ample power for the standard control loads found in ESAB's heavy-duty equipment. The wide input voltage range (380V, 400V, 415V, 480V) makes it versatile for machines deployed in various industrial environments where 3-phase power is standard. Using genuine OEM parts like this transformer is crucial for maintaining the safety certifications and operational reliability of your equipment. Generic transformers may not match the specific impedance, mounting dimensions, or thermal characteristics required by the welder's design, potentially leading to premature failure or erratic machine behavior.

This unit is built to ESAB's rigorous standards, featuring high-quality copper windings and durable insulation materials capable of withstanding the thermal cycling and vibration common in welding environments. Whether you are performing preventative maintenance or repairing a downed machine, installing the correct specification transformer is the first step in ensuring your welding operations continue without interruption.
