32221 - ESAB 32221 Input Power Terminal Board 230/460/575V

Reliable Power Connection for Industrial Welders

The ESAB 32221 Input Terminal Board is a critical component designed to manage the primary power input for select ESAB welding machines. In industrial environments, the integrity of your power connection is paramount not only for the performance of the welder but also for the safety of the operator and the facility. This genuine OEM replacement board is engineered to handle multiple voltage configurations, specifically 230V, 460V, and 575V, making it a versatile part for facilities with varying power infrastructures.

Why Choose Genuine ESAB Parts?

When repairing high-performance welding equipment, using genuine ESAB parts like the 32221 ensures that your machine operates within its factory specifications. Aftermarket or generic terminal blocks may not handle the thermal cycling and high amperage loads that industrial welders generate. This board features high-quality insulation materials and robust conductive terminals that resist arcing and heat buildup, common causes of failure in power input sections.

Symptoms of a Faulty Input Board

Over time, vibrations and thermal expansion can cause connections on the input terminal board to loosen. This leads to increased resistance, heat generation, and eventually, burnt terminals or melted insulation. If your welding machine is experiencing intermittent power loss, tripping breakers, or if you smell burning plastic near the power input area, it is essential to inspect the input terminal board. Replacing a damaged board with the ESAB 32221 restores the solid electrical foundation your machine needs to deliver stable welding arcs.

Installation and Safety

This terminal board is designed for direct replacement, ensuring bolt-holes and wire positions align perfectly with your existing setup. However, working with primary input voltage involves significant risk. Installation should always be performed by a qualified electrician or certified welding equipment repair technician. Ensure the machine is disconnected from all power sources and capacitors are discharged before attempting replacement.
