These T-035 MIG contact tips come as a 20-piece pack of copper tips with a 0.035 in (0.9 mm) bore, listed for Bernard Centerfire MIG guns. They are a sensible bulk buy if your gun uses Centerfire consumables and you run 0.035 in wire. They are the wrong choice if you have a Tweco, Lincoln Magnum or Miller style gun, or if you weld with a different wire diameter.

What it is and who it suits
This is a replacement-parts pack for people who change tips often. Copper has good electrical and thermal conductivity, which is why it is a common tip material. Because the tips are consumable, a box of twenty means you can swap one at the first sign of trouble instead of fighting a worn one.
It fits home shops, auto repair benches and fabrication shops that already run Bernard Centerfire guns on 0.035 in wire.
How to check it fits your gun
- Identify your gun brand and series from the handle label or manual. The tip must be a Centerfire style.
- Compare the tip length, thread and head shape with a tip you already have.
- Confirm the tip bore is right for your wire: 0.035 in tip for 0.035 in wire.
- Check that your nozzle, diffuser and tip belong to the same system.
- If you are buying for a Miller, Tweco or Lincoln gun, search for that series instead.
Pros and limitations
Pros
- Copper is a standard material for contact tips.
- Twenty tips give you a long supply for production or practice.
- Bulk packs usually lower the cost per tip compared with buying singles. Check the current price.
Limitations
- One bore size and one gun family.
- Not a solution for aluminum. Aluminum MIG usually needs a spool gun or a push-pull gun, Teflon or nylon liner, U-groove drive rolls, 100 percent argon and tips sized for aluminum wire. Do not assume steel tips suit it.
- Soft copper can wear faster on abrasive flux-core wire, so expect to change tips more often.
- Few reviews are available for this listing, so verify the first tip before using the whole pack.
Using and replacing the tips
- Let the gun cool and disconnect power.
- Remove the nozzle and unscrew the old tip.
- Clean spatter from the diffuser and nozzle.
- Fit the new tip firmly. Trim the wire and recheck stick-out.
- Dip the nozzle in anti-spatter compound, if you use it, before welding.
Replace a tip when the arc stutters, the wire welds to the tip, or the hole becomes slotted. Keep spare tips in a dry bag to prevent corrosion. Wear gloves because tips stay hot.

Frequently Asked Questions
What gun do these T-035 contact tips fit?
The listing says Bernard Centerfire MIG guns. They are not a universal tip. Compare the thread, length and head shape with your current tip before ordering, especially if you own a Tweco, Lincoln or Miller gun.
Can I use T-035 tips for aluminum wire?
Do not assume so. Aluminum MIG welding usually needs a spool gun or push-pull gun, a soft liner, U-groove rolls and 100 percent argon. Contact tip size and type must match the aluminum wire diameter.
How often should I change a contact tip?
Change it when the arc is unstable, the wire sticks, or the bore looks oval. It depends on amperage, duty cycle and wire type. Flux-core wire tends to wear tips faster than solid wire.
Is a copper tip better than a brass tip?
Copper conducts better, brass can be more wear-resistant. Both are widely used for steel wire. Pick based on fit, wire type, duty cycle and what your gun manufacturer recommends.
Conclusion
This 20-pack is a low-effort way to keep Bernard Centerfire guns running on 0.035 in wire. Check the gun family first, because tip styles do not cross over.
