279263 - Miller 279263 Compression Spring .312 OD x .250 ID (10-Pack)

Keep Your Miller Welder Running Smoothly

Don't let a broken spring stop your production line or delay a critical project. The Miller 279263 Compression Spring is the genuine replacement part you need to get your Miller welding machine back in top fighting shape. We know that in a busy weld shop, it is often the smallest parts that cause the biggest headaches when they fail. Whether you are dealing with a sticky trigger, a loose tensioner, or a worn-out drive assembly, replacing tired springs is a simple maintenance task that can drastically improve the feel and function of your equipment.

This pack contains 10 genuine Miller springs, giving you plenty of spares for your toolbox or parts bin. Why buy a pack of 10? Because springs are notorious for flying across the shop floor during installation, never to be seen again. Having a backup supply means you are always ready for the next repair. These springs are built to the exact factory specifications: 0.312 inches wide and with a specific tension rate of 5.2 lbs per inch. This means you don't have to guess if a hardware store spring will work—you know this one fits because it was made by Miller, for Miller.

Using genuine parts protects your investment. A spring with too much tension can cause premature wear on plastic gears or housings, while a spring with too little tension can cause slippage and poor performance. The Miller 279263 is designed to provide the perfect balance, restoring your machine to its factory settings. Before ordering, we recommend checking your machine's parts manual or using your serial number to verify that this specific spring (Part #279263) is the correct match for your model. Trust the experts at Welders Supply to keep you stocked with the authentic parts that keep your arcs burning.
