These 000-068 MIG contact tips come as a 20-piece pack of 0.035 in (0.9 mm) copper tips, listed for Miller M-series guns (M-10, M-15, M-25, M-40) and Hobart guns. It also lists a match with gas diffuser 169716. It is a good fit if you run one of those guns on 0.035 in wire and go through tips regularly. For other gun families or wire sizes, look for a different part number.

What it is and who it suits
This pack suits owners of Miller or Hobart MIG machines who burn through tips on a regular schedule, such as small shops, auto repair benches and busy hobbyists. Buying twenty at a time keeps the cost per tip down and avoids waiting on shipping.
Because these are the same style as the 000-068 tip covered in other pages on this site, the main difference is quantity. Choose the size of pack that matches your usage.
How to check it fits your gun
- Match the gun model to your manual. M-series and H-series guns look alike but have different parts across generations.
- Compare the tip with one you already have. Look at length, thread and the shape of the base.
- Check the diffuser. If your diffuser is the 169716 style the listing mentions, the tip should thread in. Otherwise, check what thread your diffuser uses.
- Check the wire. These are for 0.035 in wire.
- Check that your nozzle is the correct size so the tip sits where the gun maker intended.
Pros and limitations
Pros
- A 20-pack covers a lot of tip changes.
- Copper is a common, conductive tip material.
- Quick and tool-light to install.
Limitations
- One wire size and one tip style.
- For steel wire. Aluminum wire needs different tips and a different feeding setup, so do not assume these suit it.
- The packaging may not include a storage case, so keep the tips in a labeled box to avoid mixing sizes.
- Quality can vary between third-party sellers. If feeding is rough with a fresh tip, compare it with an original.
Replacing and storing tips
- Power off, unplug and let the gun cool.
- Remove the nozzle and unscrew the tip.
- Check the diffuser and clean spatter from the nozzle.
- Thread in the new tip until snug, not forced.
- Trim the wire to a clean end and recheck stick-out.
Label a container with tip size so you do not use a 0.030 in tip with 0.035 in wire by mistake. Wear gloves and a rated helmet, and ventilate your work area.

Frequently Asked Questions
Which guns do the 000-068 contact tips fit?
The listing names Miller M-10, M-15, M-25 and M-40 guns and Hobart guns. Verify against your gun manual and compare an existing tip, because model years and revisions can differ.
What wire size are 000-068 tips for?
They are 0.035 in (0.9 mm) tips for 0.035 in wire. Use a different part number for 0.030 in or 0.045 in wire, and always match the bore to the wire diameter.
Can I use them with aluminum wire?
Not as a general rule. They are intended for steel wire. Aluminum MIG needs the right liner, drive rolls, 100 percent argon and typically a spool or push-pull gun with tips made for aluminum wire.
How many tips will I use?
It varies with amperage, duty cycle, wire type and technique. Flux-core wire tends to wear tips faster. A 20-pack lasts regular users a long time and ensures you always have a spare.
Conclusion
The 20-piece 000-068 pack is a practical bulk supply for Miller M-series and Hobart guns on 0.035 in wire. Verify your gun and diffuser, then keep the tips organized.
