OVERVIEW

Genuine ESAB 13735590 Replacement Contactor

The ESAB 13735590 is a heavy-duty, single-pole contactor designed specifically for the rigorous demands of industrial welding equipment. Engineered to handle high-amperage direct current (DC) loads, this component is critical for the safe and effective operation of welding power sources. With a contact rating of 500 Amps, it is capable of managing the substantial power output required for MIG, TIG, and Stick welding processes in heavy fabrication environments. The unit is activated by a 12V DC coil, making it compatible with standard low-voltage control circuits found in many modern and legacy ESAB machines.

Contactors in welding machines act as the primary switch for the welding current. When the trigger is pulled, the control circuit energizes the 12V coil, closing the heavy-duty contacts and allowing the 500A welding current to flow to the torch or electrode. Over time, the high electrical loads and frequent cycling can cause the internal contact points to pit, burn, or weld shut. Replacing a worn contactor with this genuine ESAB part ensures that your machine maintains a stable arc and stops output immediately when the trigger is released, which is vital for operator safety and weld quality.

This specific model features a robust housing that protects the internal mechanism from dust and debris common in workshop environments. The terminals are designed for secure, high-conductivity connections to minimize resistance and heat buildup. Whether you are performing routine maintenance or repairing a breakdown, using genuine OEM parts like the 13735590 ensures compatibility with your equipment's mounting points and electrical specifications. It is an essential spare part for maintenance departments managing fleets of high-output welding power sources.

FAQ

The coil voltage for the ESAB 13735590 contactor is 12V DC. Ensure your machine's control circuit provides this specific voltage before installation.

This contactor is rated for 500 Amps DC, making it suitable for heavy-duty industrial welding applications.

This is a 1-Pole (single-pole) contactor, typically used to break one leg of the DC welding output.

Common symptoms include the machine having no output despite clicking (stuck open), the electrode being live constantly (stuck closed), or erratic arc performance.

This contactor is specified for 500ADC (Direct Current). While some contactors can handle AC, you must verify the specific requirements of your machine. It is primarily designed for DC output switching.

Yes, the ESAB 13735590 is a genuine OEM replacement part designed to meet the original manufacturer's specifications.

Typically, contactors are sold as the unit itself. You will usually need to reuse the existing mounting hardware from your machine.

12VDC refers to the voltage required to energize the magnetic coil that pulls the contacts closed. It is distinct from the 500A rating, which is what flows through the contacts.
