995104 - ESAB 995104 MOV 150V 10J Surge Protector

Restore Your Welder's Protection

When your welding machine goes down due to a power surge, it often means a small, inexpensive part has done its job to save the rest of the system. The ESAB 995104 MOV (Metal Oxide Varistor) is that hero component. Designed specifically for ESAB welding power sources, this 150V, 10J varistor is the exact replacement part you need to repair blown surge protection circuits. If you have opened up your welder to find a small, disc-shaped component that is cracked, burnt, or blackened on the main power board, chances are it is the MOV, and replacing it is the first step to getting your machine back in action.

Welding machines are expensive investments, and they are often subjected to harsh electrical environments. Generators, long extension cords, and other heavy machinery on the same circuit can create voltage spikes that threaten the delicate electronics inside your welder. The 995104 MOV stands guard, absorbing these harmful spikes before they can fry your main control board or inverter modules. It is essentially a fuse for voltage rather than current. Because it is a sacrificial part, it is smart to keep a few of these in your repair kit or maintenance locker, especially if you operate in areas with unstable power grids.

Installation typically requires basic soldering skills, as this is a through-hole component mounted directly to the PCB. By choosing the genuine ESAB 995104, you ensure that the clamping voltage and energy rating match the original design of your welder perfectly. Don't risk your equipment with unmatched generic parts. Use the correct 150V 10J varistor to maintain the factory safety standards of your ESAB machine. This simple repair can save you thousands of dollars in replacement boards and minimize downtime in your shop.
