OVERVIEW

Reliable Performance with Tweco 16S-40 Contact Tips

Every welder knows that the contact tip is the unsung hero of the MIG gun. It’s the final point of contact where the welding current is transferred to the wire, and its condition directly impacts the quality of your arc. If you are running 0.040" (1.0mm) wire through a Tweco Professional or Spray Master gun, the Tweco 16S-40 Contact Tip is the genuine replacement part you need to keep your welds smooth and your spatter low. Don't let a worn-out tip frustrate you with burn-backs or an unstable arc; keep your gun running like new with these high-quality copper tips.

Designed to withstand the heat of the job, these standard-duty tips are built from premium copper alloy that resists overheating and premature wear. The 16 Series is a staple in the industry, known for its durability in medium to heavy-duty applications. Whether you are welding structural beams or fabricating parts in the shop, these tips provide the consistent wire feeding you rely on. The 0.040" bore is precision-machined to prevent the wire from wandering, ensuring the arc goes exactly where you point it.

This convenient 25-pack is perfect for busy shops. Running out of consumables in the middle of a project is a headache you don't need. By stocking up with this bulk pack, you ensure that you always have a fresh tip on hand when you need it. Compatible with the popular Tweco #3, #4, and #5 guns, as well as the Spray Master 350 and 450, these tips screw in easily with a secure 3/8"-24 thread. Swap them out regularly to maintain peak performance and produce the high-quality welds your clients expect.

FAQ

The 16S-40 contact tip is designed specifically for 0.040-inch (1.0mm) welding wire.

This tip fits Tweco Professional Series No. 3, No. 4, and No. 5 guns, as well as Tweco Spray Master 350 and 450 series guns.

The tip features a standard 3/8"-24 UNF thread for connection to the gas diffuser.

This package contains 25 individual contact tips.

The primary difference is the thread size and physical dimensions. 14 Series tips typically use a 1/4"-28 thread, while 16 Series tips use a larger 3/8"-24 thread and are generally used for higher amperage applications.

It is manufactured from a high-conductivity copper alloy designed for efficient current transfer and heat resistance.

As wire feeds through the tip, it wears the bore into an oval shape (keyholing), which causes poor electrical contact and an unstable arc. Changing the tip restores performance.
