What it is and who it suits
Hobart is a Miller Electric brand, so its consumables are made to match its own guns. This tip suits owners who run .023 inch wire, often on thin sheet metal, and want an OEM-branded consumable instead of a generic one.
If you run .030 or .035 inch wire, you need a different tip. Hobart sells those under other part numbers.
How to check it fits your gun
- Look up your machine’s gun in the Hobart or Miller manual and note the contact tip part number.
- Compare it to 770174. If your parts list gives a different number, check the listing carefully.
- Confirm you run .023 inch wire. The tip bore should match the wire diameter.
- Check that the tip’s thread and length match your diffuser.
- Confirm the pack size is five before comparing price per tip.
Pros and limitations
- Pros: Clear part number you can verify with Hobart’s own page; brand-matched design; pack of five.
- Limitations: Only one wire size; a small pack for heavy users; and the listing does not give copper grade details. Machines listed may have more than one gun style.
Installing and caring for contact tips
- Switch off the welder and let the gun cool.
- Unscrew the nozzle, remove the old tip, and fit the new one snugly into the diffuser.
- Clean spatter from the nozzle before refitting.
- Replace the tip at the first sign of wire sticking, arc wander or burn-back.
- Wear a welding helmet and gloves, and keep the area ventilated.

Frequently Asked Questions
What wire size is the Hobart 770174 tip for?
Hobart lists 770174 as a .023 inch contact tip, sold as a pack of five. Use it with .023 inch wire. A tip that is too large for the wire causes arc wander, while one that is too small makes the wire stick and feed poorly.
Which welders does it fit?
The listing names Millermatic and Hobart machines including Handler 135 and 175, Ironman 250 and Beta-MIG. Tips differ by gun style, so check your gun’s parts list for the 770174 or the part number your gun uses, instead of assuming by brand.
How many tips come in a pack?
The listing is a pack of five. Compare that with the price per tip when you check current Amazon pricing, and consider keeping a few spares since contact tips are consumable wear parts.
Can I use .023 tips for aluminum or flux-core wire?
This tip is sized for .023 inch wire. Aluminum usually needs a larger bore for expansion and a different liner and drive rolls, while flux-core wire often needs other tip and roll choices. Check your wire’s instructions and machine manual.
Verdict
A solid choice for .023 inch wire on a Hobart or Miller gun that uses this tip. Check your parts list before you buy.
