OVERVIEW

Restore Your Welder's Performance

When your Miller welder isn't running right, it costs you time and money. The Miller 167374 Capacitor is a genuine replacement part designed to get your machine back up and running like new. Capacitors are hardworking components inside your welder that help manage power flow, and over time, they can wear out, bulge, or fail completely. If your machine is humming but not welding, or if you are experiencing erratic power issues, a faulty capacitor could be the blame.

This replacement unit is a robust 8µF, 400VDC capacitor built to handle the rigors of the shop. Because it is a genuine Miller part, you don't have to worry about whether it will fit or if the terminals are in the right place—it drops right in where the old one came out. Using generic electrical parts in a high-performance welder can be risky; stick with OEM components to ensure your warranty stays intact and your machine stays safe.

Don't let a small electrical part stop your production. Keep your equipment maintained with the correct parts. This capacitor is commonly found in various Miller power sources. Always check your owner's manual or parts diagram to confirm the part number before ordering, and remember to follow proper safety procedures when discharging and replacing capacitors.

FAQ

This capacitor is rated at 8 microfarads (µF).

It has a voltage rating of 400 VDC (Volts Direct Current).

Yes, this is a genuine Miller OEM part, SKU 167374.

Signs of a bad capacitor can include physical bulging, leaking fluid, the machine humming but not working, or the capacitor failing a capacitance test with a multimeter.

It utilizes metallized polypropylene film (Polyp Met Film).

Yes, capacitors can store a lethal electrical charge even when power is disconnected. Always safely discharge the capacitor according to safety standards before handling.

The tolerance is 10%, meaning the actual capacitance can vary by +/- 10% of the rated 8µF.

No, you should always match the voltage and capacitance ratings specified by the manufacturer. Using a lower voltage rating can cause the capacitor to fail catastrophically.
