OVERVIEW

Smooth Arc Performance with Tweco WS14-45 Tips

Every welder knows that the contact tip is the final transfer point for welding current, making it one of the most critical components in your MIG gun setup. The Tweco WeldSkill WS14-45 (1140-1169) contact tip is built to deliver consistent current transfer for 0.045-inch wire, ensuring a stable arc and reduced spatter. Whether you are welding mild steel, stainless, or running flux-cored wire, these tips provide the reliability you need to lay down high-quality beads without constant interruptions.

Designed to fit the popular Tweco 14 Series platform, these tips are compatible with a huge range of MIG guns, including the classic Tweco #1 and #2, WeldSkill 140/180/220/400, and many other aftermarket guns that use the 14-series style. The copper construction handles heat effectively, resisting the keyholing effect that causes erratic arcs. The bore is smooth and perfectly sized for 0.045" wire, preventing the "stick-slip" feeding issues that can ruin a weld or cause burnback.

This package contains 25 contact tips, which is a smart investment for any serious welder or shop. Contact tips are consumable items that wear out with heat and wire friction; trying to extend the life of a worn tip often leads to poor arc starts and wandering arcs. With this 25-pack, you can afford to change your tip as soon as performance drops, keeping your welds clean and your frustration low. Upgrade your consumables to genuine Tweco WeldSkill parts and experience the difference in your wire feeding and arc stability.

Why Choose Tweco WeldSkill?

  • Consistent Feeding: Smooth bore reduces drag on the wire.
  • Better Starts: clean electrical contact ensures instant arc ignition.
  • Value: Professional quality at a price point that makes sense for daily use.
  • Universal Fit: Fits the industry-standard 14-series diffusers found on thousands of machines.

FAQ

The WS14-45 is designed for use with 0.045-inch (1.2mm) welding wire.

It is compatible only if the gun is equipped with a Tweco-style 14 Series front end (diffuser). Many aftermarket guns for Miller and Lincoln machines use Tweco-style consumables, but you must verify your specific gun's series.

This SKU (1140-1169) contains a package of 25 contact tips.

The tip features a standard 1/4"-28 UNF thread.

WeldSkill is Tweco's line designed for value and general-purpose applications, while maintaining high manufacturing standards. They are dimensionally interchangeable with standard Tweco 14 series tips.

While physically possible, aluminum wire typically expands more when heated. It is often recommended to use a tip specifically oversized for aluminum (often marked with an 'A') or go up one size to prevent seizing, though 0.045 tips are sometimes used for 0.045 aluminum in non-critical applications.

These contact tips are manufactured from a high-grade copper alloy designed for optimal electrical conductivity and thermal resistance.

The internal stock code is TWE1140-1169.
