OVERVIEW

Keep Your Tregaskiss Gun Tough with the 402-11 Shock Washer

Every welder knows that the secret to a smooth day under the hood lies in the condition of their consumables. The Tregaskiss 402-11 Shock Washer might look like a small ring, but it plays a huge role in keeping your 300A or 400A MIG gun performing at its best. This little hero sits right behind your nozzle, acting as a buffer that takes the heat so your expensive gun neck doesn't have to. It helps keep your nozzle snug and centered, which is crucial for maintaining that perfect shielding gas coverage over your weld pool.

Over time, heat and spatter take their toll on everything at the front of the gun. A worn-out shock washer can cause your nozzle to wobble, leak gas, or even get stuck so bad you need a vice to get it off. By swapping in a fresh, genuine Tregaskiss OEM shock washer, you ensure that your nozzle threads on smoothly and stays put, even when you're running hot and fast. It's designed to handle the abuse of daily welding, resisting the cracking and melting that cheap knock-offs often succumb to.

Whether you are welding mild steel, stainless, or running aluminum wire, having a fresh shock washer is key to preventing internal spatter buildup that can short out your contact tip or block your gas flow. It's one of those cheap insurance parts that saves you from the headache of troubleshooting porosity or an unstable arc later on. Don't let a ten-dollar part ruin a thousand-dollar job; keep a few of these 402-11 washers in your toolbox.

Installation is a breeze—just pop off your nozzle, remove the old washer, slide this new one in, and you're back in business. It fits perfectly because it's made by the same people who built your gun. Trusting OEM parts means you spend less time fighting your equipment and more time laying down beads. Keep your Tregaskiss gun running like new with the part that was made for it.
