Tips, nozzles & liners

The best welding torch consumables for 2026

Most « the machine has stopped feeding properly » problems are a worn contact tip or a kinked liner. We cover contact tips and how to size them to the wire, gas nozzles, diffusers, and liners — including the compatibility question that catches everyone: which torch standard you own. Three families turn up on this page and none of their parts fit the others: MIG torches in the MB15 and MB25 patterns, TIG torches in the WP-9, 20 and 25 series, and air plasma torches of the AG-60 and SG-55 type.

  7. Five STARTECHWELD 45V43 TIG gas lens collet bodies

Choosing within torch parts, by need

Matching the torch to the wire used

The contact tip and the liner are sized for a precise wire diameter. A mismatch birdnests the wire or destabilizes the arc.

STM Der Meisterladen MB25/250 wear parts set, M6, 1.0 mm

Bringing a torch back into service

A tired torch is repaired part by part for a fraction of the price of a new one.

YESWELDER YW-100L-0.8

Finding the part months later

A torch is serviced for years, and its contact tip is changed every few hours of arc. References still in distribution beat an exotic torch whose consumables vanish.

Torch parts and who each one is for

Unstable arc
A worn contact tip is the first thing to check. It is the cheapest part and the one most often responsible.
Wire birdnesting
A fouled or unsuitable liner: a steel liner does not suit aluminum, which demands a PTFE liner.
Stuck spatter
A cup full of spatter disturbs the gas flow. An anti-spatter spray and regular cleaning are enough.

The trade-offs of torch parts

The torch maker’s consumable or a pattern one
Generic contact tips cost a fraction and have variable tolerances. On this part, the difference in quality is felt immediately.
Copper against alloys
Copper contact tips conduct best and go oval quickly; alloys last longer and conduct slightly less well.
Stock in advance against real need
A few contact tips and a spare cup avoid stopping a job. Beyond that, the parts sit unused.

What keeps coming up about torch parts

When should the contact tip be changed?

As soon as the arc turns unstable or the hole goes oval. It is the cheapest part and the one most often behind arc problems.

Why does my wire birdnest?

A fouled liner, badly set drive rolls, or a worn contact tip. Check those three before suspecting the machine.

Do I need a special liner for aluminum?

Yes, PTFE or equivalent. Aluminum wire is soft and drags in a steel liner until it birdnests.

How do I stop spatter sticking?

An anti-spatter spray or paste on the cup and contact tip. Cleaning the cup is also part of routine maintenance.

Is the thread standard?

It depends on the type of torch. Common torches follow market standards, but checking before buying is essential.

How do I clean the liner?

By removing it and blowing it through with compressed air, torch straightened out. A heavily fouled liner is replaced, not recovered.

Does the swan neck wear out?

It distorts with repeated bending and the wire path degrades. It is a spare part worth knowing about.

Should the nozzle be changed with the contact tip?

Not at the same rate: the tip wears inside, the nozzle loads up with spatter. You clean the nozzle every spool and replace it only when the mouth is deformed.

In short, on torch parts

The contact tip is the cheapest part and the one most often guilty of an unstable arc: change it before suspecting the machine. Aluminum wire demands a PTFE liner, and a heavily fouled liner is replaced rather than cleaned.

Torch parts at a glance

  • Wire diameter: 0.8 to 1 mm (0.04 in), on 3 of the 11 models.

Torch parts, side by side

There is no table here, and the reason is in the listings. The figure published most often across these 11 products is contents, given by 5 of them — short of the four in five a column needs to compare rather than to display gaps. Each product page says what its own maker published.
