403-3-45 - 403-3-45 Heavy Duty Tapered Contact Tip for .045 Wire (25 Pack)

Keep Your Arc Smooth and Your Downtime Low

Every welder knows that the contact tip is the unsung hero of the MIG gun. It’s the final transfer point for all that welding current, and when it fails, your whole operation grinds to a halt. The 403-3-45 Heavy Duty Tapered Contact Tip is built to keep you welding longer and troubleshooting less. Designed for .045 wire, this tip is a workhorse for structural and heavy fabrication jobs where heat buildup is a constant battle. The heavy-duty copper construction acts as a superior heat sink, pulling thermal energy away from the wire exit point to prevent the tip from overheating and keyholing.

Struggling to see the puddle in a tight corner? The tapered design of this tip is a game-changer. By narrowing at the end, it gives you a better line of sight to the weld pool, allowing for more precise gun manipulation and better bead placement. This is especially helpful when you are working in tight fixtures or welding inside corners where a standard blunt tip blocks your view. The taper also helps direct shielding gas right where you need it, reducing porosity and cleanup time.

We know that in a busy shop, grabbing the wrong part happens. That’s why each of these tips is clearly marked with the part number. No more squinting at a dirty tip trying to guess if it’s for .035 or .045 wire. This 25-pack is perfect for the toolbox or the supply cabinet, ensuring you aren't left scrambling for a fresh tip in the middle of a hot pass. Compatible with your trusty Tregaskiss style guns, these tips slide right into your existing diffuser or retaining head setup.

Don't let burnback and erratic arcs ruin your day. Upgrade to a heavy-duty tip that can take the heat. Whether you are pushing hard on mild steel or running spray transfer, the 403-3-45 delivers the consistent electrical contact you need for a stable, buttery smooth arc. Stock up with this bulk pack and keep the sparks flying for all the right reasons.
