11H-35 Heavy Duty Contact Tip .035 for Tweco MIG Guns (25 Pack)

Keep Your Arc Smooth and Your Downtime Low

Every welder knows that the contact tip is the smallest part of the gun but causes the biggest headaches when it fails. If you are running .035 wire through a Tweco setup, the 11H-35 Tweco Style Heavy Duty Contact Tip is the replacement you need to keep burning wire without constant interruptions. These aren't your flimsy standard tips; the "H" stands for Heavy Duty, meaning they have thicker walls and more copper. Why does that matter? Because more copper means it handles heat better. When you are welding long beads or cranking up the heat, a standard tip can get too hot, soften, and start grabbing the wire. These heavy-duty tips stay cooler, letting the wire slide through smoothly for longer.

These tips are built to be a direct swap for the genuine Tweco 11H-35. They fit perfectly into your Tweco Spray Master 250 or the old reliable Tweco Classic guns. Just make sure you are using the HD52-11 gas diffuser—that’s the heavy-duty diffuser made to match these tips. If you try to jam this into a standard diffuser, it won't seat right, and your gas coverage will be all over the place. Getting the right fit means your nozzle stays centered, your gas flows smooth, and your welds look like a stack of dimes instead of a bird's nest.

We know that in a busy shop, you go through tips like candy. That's why these are sold in packs of 25. You can toss a handful in your toolbox or keep the box on the cart so you're never searching for a fresh one when the arc starts sputtering. Whether you are welding mild steel, stainless, or doing some repair work on the weekend, having a fresh, high-quality contact tip is the cheapest insurance policy for a good weld. Stop fighting the burn-back and erratic arcs caused by worn-out tips and load up with these heavy-duty replacements.
