An order for “Bernard .035 tips” leaves out the detail that separates T-035 from TT-035. Before buying another bag, identify the complete part number and the nozzle configuration on the gun. Matching the wire diameter is only the start of the check.
T-035 is the standard, non-tapered Centerfire contact tip; TT-035 is the tapered version. Both are listed for 0.035-inch wire, but they are different parts. Miller’s individual product listings identify their different shapes and lengths: T-035 specifications and TT-035 specifications.
T-035 and TT-035: the useful differences
| Check | Standard tip | Tapered tip |
|---|---|---|
| Manufacturer part number | T-035 | TT-035 |
| Consumable family | Centerfire | Centerfire |
| Tip style | Non-tapered body | Tapered |
| Listed length | 1.5 inches | 2 inches |
| Listed wire size | 0.035 inch (0.9 mm) | 0.035 inch (0.9 mm) |
| Material | Copper | Copper |
The table uses the manufacturer’s T-035 listing and manufacturer’s TT-035 listing. Dimensions are identification checks, not permission to substitute one part into an unverified assembly.
“Tapered base” does not necessarily mean a TT-series tip
There are two different descriptions to keep straight. Miller describes T-035 as having a non-tapered body with a tapered base. Its TT-035 listing identifies the tip style as tapered. Therefore, a seller’s phrase “tapered base” alone does not establish that the item is TT-035. Read the complete manufacturer part number rather than selecting by a few words in a listing.
Neither of these Centerfire tips is a screw-in contact tip. Both manufacturer listings describe a threadless, drop-in design. Do not interpret the extra T in TT-035 as meaning “threaded,” or try to establish compatibility by comparing a thread size that these tips do not have. See the T-035 design description and TT-035 design description.
Check the nozzle and diffuser before changing tip styles
Bernard treats the tip, nozzle, diffuser, and insulator as a consumable system. Its Centerfire parts chart lists standard and tapered tips separately. It also specifically excludes the tapered TT series from Centerfire HD-series use, while listing the standard T series for Centerfire and Centerfire HD.
That is why “both are Centerfire” is not enough to approve a substitution. Compare the nozzle and diffuser numbers against the correct gun documentation. A gun’s brand name, or a photo of a similar-looking gun, is not a complete identification of its installed front-end parts.
When replacing a proven setup, match its documented parts rather than redesigning the front end during a restock. When intentionally changing the setup, have the complete combination checked first. The question to resolve is not merely whether the wire passes through the tip; it is whether the manufacturer lists that tip for the intended assembly.
For the separate question of whether worn front-end parts need attention, see the WSP MIG nozzle and diffuser replacement guide. Do not use a tip purchase as a substitute for identifying a damaged or mismatched assembly.
A four-item check before placing the order
1. Record the full part number. Keep a photo of the last correctly supplied package when available. Write T-035 or TT-035 in the purchasing record, not simply “.035 Bernard.” Preserve any additional suffixes rather than assuming they are optional. When a worn part cannot be identified, mark the number Unknown instead of choosing the closest search result.
2. Identify the installed system. Record the gun model plus the nozzle and diffuser numbers. A machine model is useful background, but the gun and front-end configuration are the items being checked. Compare them with the applicable manufacturer parts breakdown before treating a previous order as proof of fit.
3. Compare the complete listing. Check the selected part number, wire size, tip style, and package quantity together. A correct photograph beside an incorrect variation selection still leaves an unresolved order. Ask the supplier to clarify conflicting details before checking out; do not silently decide which field must be right.
4. Separate pieces from packs. Put the requested piece count and pack size on the order. For example, “10 pieces, supplied as one 10-pack” is clearer than “quantity 10.” Check the seller’s actual unit of sale instead of assuming that every supplier uses the same packaging.
Do not confuse these with AccuLock part numbers
Bernard’s AccuLock S chart lists T-A035CH and TT-A035CH among its 0.035-inch contact tips. Those are not alternate spellings of T-035 and TT-035. The shared wire-size digits do not establish a cross-reference between consumable families.
For a gun fitted with AccuLock consumables, use its corresponding parts documentation. Do not shorten a recorded number by dropping the A or the ending letters. A useful shop record keeps the original manufacturer number intact, even when a supplier adds a separate internal stock number.
Inspect safely, and stop when identification is uncertain
Before handling the gun’s front end, follow the shutdown and maintenance precautions in the gun and power-source manuals. Disconnect power as instructed and let hot components cool. This article is an ordering guide, not a replacement for the equipment’s service procedure or an approved welding procedure.
Do not force a questionable combination together, modify a replacement tip to make it fit, or run a production weld to decide whether an unidentified part is acceptable. Resolve the part numbers first. Bernard’s manufacturer support and documentation resources provide a route to the applicable gun manuals and help with replacement-part questions.
Ordering from Arc Weld
Arc Weld lists Bernard T-035 standard Centerfire tips in a 10-pack and Bernard TT-035 tapered Centerfire tips in a set of 10. Choose the listing that matches the verified setup, not whichever one happens to appear first in search. Confirm the current price, stock, and unit of sale on the product page before ordering.
The featured image is the TT-035 product image from Arc Weld’s catalog. It is not a side-by-side comparison or a dimensional drawing; use the manufacturer information above for the differences between the two parts.
Make the next reorder easier
Create a separate bin label for each approved part. A useful label includes the manufacturer, complete part number, wire size, assigned gun or station, and matching nozzle number. Attach the same information to the purchasing record so the person placing the order does not have to reconstruct the setup from an old photograph.
Keep unknown fields visibly unresolved. For a gun that has not yet been identified, start with the Weld Support Parts lookup resources and then confirm the resulting parts against the manufacturer documentation. The next useful action is a verified parts record, not another guess at a contact-tip number.
