0319470015 - ESAB LAE Series Replacement Control Transformer

Restore Precision to Your ESAB LAE Power Source

The ESAB 0319470015 Control Transformer is a critical component designed specifically for the maintenance and repair of ESAB's robust LAE series welding rectifiers. In the world of heavy industrial welding, the LAE series (including models like the LAE 800, LAE 1000, and LAE 1250) is renowned for its durability and performance in submerged arc and high-amperage MIG applications. The control transformer plays a vital role in this ecosystem, stepping down the high input line voltage to a safer, usable level for the machine's internal control circuits, contactors, and logic boards.

Using a genuine OEM part like the 0319470015 ensures that the electrical characteristics—such as impedance, voltage regulation, and thermal dissipation—match the original engineering specifications of the power source. Generic transformers may not handle the specific inductive loads or the rapid load changes characteristic of welding operations, potentially leading to premature failure or erratic machine behavior. This transformer is built with high-grade copper windings and superior insulation varnish to withstand the thermal cycling and vibration found in heavy fabrication environments.

Electrical integrity is paramount when repairing high-output welding equipment. This component ensures that the control logic receives clean, stable power, which is essential for maintaining consistent arc characteristics and wire feed speeds. Whether you are performing a scheduled overhaul or an emergency repair, installing the correct ESAB control transformer is the best way to guarantee the continued reliability and safety of your capital equipment.
