Learn why Tweco 16S contact tips fit the HTP TW400-16s-15 MIG gun, what sizes are available, and how to choose the right one for your welding.
Quick Answer
Yes, Tweco 16S contact tips are the correct replacement for the HTP TW400-16s-15 MIG gun, but you must select the right wire size before ordering.
Why Fitment Depends on the Gun Model
A common mistake is assuming all contact tips are interchangeable. The HTP TW400-16s-15 MIG gun is designed to use Tweco 16S contact tips, not the 15 Series or other styles. This specific compatibility ensures proper current transfer and wire feeding.
If you use a different tip style, you risk poor arc stability, erratic wire feed, or even damage to the gun's liner. Always confirm your gun model before purchasing.
Size Selection Is Critical
The 10-pack of Tweco 16S contact tips is available in .035, .045, .052, and 1/16 inch sizes. The size must match the diameter of the welding wire you are using. Using a tip that is too large can cause poor electrical contact, while a tip that is too small can clog and jam the wire.
When ordering, use the drop-down box to select the correct size. This is not a minor detail—getting it wrong means the tips won't perform as intended.
Verdicts on Common Claims
- Claim: 'Any contact tip will work.': Verdict: False. Only Tweco 16S contact tips are designed for the HTP TW400-16s-15 MIG gun. Using other styles can lead to poor performance or damage. Always verify your gun model before buying tips.
- Claim: 'Size doesn't matter much.': Verdict: False. The tip size must match your wire diameter. Choose from .035, .045, .052, or 1/16 inch in the drop-down menu. Check your wire spool label for the exact diameter.
- Claim: 'Buying a 10-pack is wasteful.': Verdict: False. Contact tips wear out and need regular replacement. A 10-pack offers a convenient supply and better value per tip. Keep spare tips on hand to avoid downtime.
