Quick Verdict
Rating: Recommended with caveats
Best For: Auto body repair users who need a replacement stud welding tip for Uni-Spotter stud gun models.

What Is the H and S Auto Shot 1004?
The H and S Auto Shot 1004 is a replacement stud welding tip for Uni-Spotter stud welding guns. It is designed to hold and set welding studs during auto body dent repair, especially when you need to pull dents with a stud welder and slide hammer setup.
The key details are simple but important. This tip uses solid copper construction for conductivity, a tapered shaft for a positive fit, and compatibility with welding studs up to 2.6 mm in diameter. It is not a complete welder, gun, or dent repair kit, so you should treat it as a replacement accessory for an existing compatible setup.
Before You Buy: Confirm that your stud welding gun uses the Uni-Spotter style tip and that your studs are 2.6 mm or smaller. This part is a replacement tip, not a universal repair solution for MIG, TIG, stick, or unrelated welding guns.
Who Should Buy It?
Best For
- Auto body repair users replacing a worn or contaminated Uni-Spotter stud tip.
- Shops that work with welding studs up to 2.6 mm in diameter.
- DIY dent repair users who already own a compatible H&S Uni-Spotter stud gun.
Skip If
- You need a full stud welder kit, not a single replacement tip.
- Your welding gun does not accept Uni-Spotter style tips.
- You plan to use studs larger than 2.6 mm.
Product Specifications and Features
The H and S Auto Shot 1004 focuses on fit, conductivity, and easy replacement. Its solid copper construction helps support current flow during stud setting, while the tapered shaft helps the tip seat securely in the compatible gun.
The compact 4.8 x 4.6 x 1.1-inch size and 0.317-ounce item weight make it easy to store in a small parts drawer, repair cart, or welding accessory organizer. Since the package is sealed, you can keep a spare tip protected until your current tip wears, becomes contaminated, or stops holding studs correctly.
Compatibility and Fit
Compatibility matters more than any other feature here. Verified product details point to use with Uni-Spotter stud gun models and welding studs up to 2.6 mm in diameter. Some retailer titles describe the part as a tip “for all guns,” but you should read that in the context of the Uni-Spotter system instead of assuming it fits every welding gun brand.
The tapered shaft helps create a positive connection inside the compatible gun. That fit matters because a loose or incorrect tip can affect stud placement, current transfer, and removal after use.
Build Quality and Materials
The 1004 uses solid copper construction, which suits this type of welding accessory because copper conducts electricity well. For a stud welding tip, conductivity and clean contact help the tool transfer power to the stud more consistently.
The design is simple, and that is part of its value. You do not get moving parts, electronics, or complicated setup steps. You get a compact replacement tip made for a specific job inside a compatible stud welding system.
Replacement and Ease of Use
The tapered design supports both secure fit and easier removal. That helps when you need to change a worn tip, clean your setup, or swap parts during regular shop work.
You should still avoid forcing the tip into the wrong gun. A stud tip should seat firmly without damage. If it feels misaligned, stop and check the gun model, stud size, and manufacturer instructions before continuing.
Pro Tip: Keep one clean spare tip with your studs and puller accessories. Replacing a worn or dirty tip before a repair session can save time and help you avoid poor stud contact during dent pulling.
How It Performs in Real Use
For Auto Body Dent Repair
In auto body dent repair, the 1004 works as the contact point between your compatible stud gun and the welding stud. When the tip fits correctly and the stud size matches, it helps you place studs for pulling dents from sheet metal panels.
This part will not fix poor surface preparation, wrong welder settings, or damaged studs. You still need clean metal, the right stud size, and proper welding technique to get reliable results.
For Shop Replacement Use
Professional shops can treat this tip as a small but useful consumable or replacement accessory. A worn tip can slow down a repair, especially when it stops gripping studs consistently or becomes contaminated.
The sealed package helps when you store extras in a repair cart or parts bin. You can keep a spare ready without leaving the copper contact area exposed to shop dust and grime.
For DIY Garage Repairs
DIY users get the most value if they already own a compatible Uni-Spotter stud welder. The part is small, lightweight, and easy to store, so it makes sense as a backup before starting a dent repair project.
The main caution is setup knowledge. If you are new to stud welding, read your welder manual first and practice on scrap material when appropriate. A replacement tip cannot make up for unsafe technique or poor panel preparation.
For Long-Term Use
Long-term performance depends on how often you weld studs, how clean your work area stays, and whether you use compatible studs. Copper tips can wear or collect debris over time, so regular inspection matters.
You should replace the tip when fit, contact, or stud holding becomes unreliable. Waiting too long can make the repair process slower and less predictable.
Setup Tips Before First Use
Start by confirming your gun model and stud size. This tip is designed around Uni-Spotter stud gun compatibility and studs up to 2.6 mm, so matching those two details helps prevent fit problems.
- Inspect the tip before installation and avoid using it if it looks damaged or misshapen.
- Keep the copper contact surface clean and free from grease, dust, and metal debris.
- Install it according to your stud welder manual instead of forcing the tapered shaft.
- Test fit with the correct stud size before starting a repair on a vehicle panel.
- Store spare tips in their packaging or a clean parts organizer until needed.
Compatibility and Safety Notes
This tip touches electrical welding equipment, so you should treat compatibility and safety seriously. Use it only with equipment that accepts this style of stud welding tip, and follow the instructions for your specific stud welder.
Wear proper eye, hand, and body protection when using stud welding equipment. Work in a suitable area, keep flammable materials away from the repair zone, and avoid using damaged tools or accessories. If you are unsure about setup, ask a qualified technician or follow the manufacturer’s service guidance.
Pros and Cons
Pros
- Solid copper construction supports good conductivity for stud welding tasks.
- Tapered shaft helps create a positive fit in compatible Uni-Spotter stud guns.
- Works with welding studs up to 2.6 mm in diameter.
- Small and lightweight enough to keep as a spare in a repair cart.
- Sealed packaging helps protect the tip before use.
Cons
- Not a full stud welder, dent puller, or complete repair kit.
- Compatibility centers on Uni-Spotter stud gun models, so it may not fit other systems.
- Not suitable for studs larger than 2.6 mm.
Is It Worth the Price?
The H and S Auto Shot 1004 is worth considering if you already use a compatible Uni-Spotter stud gun and need a replacement tip for routine dent repair work. Its value comes from the specific fit, copper construction, and simple replacement role rather than from extra features.
It is a smart buy for everyday use when a worn tip could slow down your repair process. It is not the best fit if you are still shopping for a complete stud welding system, need a different tip type, or cannot confirm compatibility with your gun.
How It Compares to Alternatives
The UNI-1004 is the stud setting tip in the Uni-Spotter accessory family. Other H&S Uni-Spotter tips, such as molding rivet or shrink tips, serve different repair tasks, so they should not be treated as direct replacements for this part.
Compared with generic stud welding tips, the H and S Auto Shot 1004 makes the most sense when you want a known match for Uni-Spotter stud gun models. A generic option may be worth comparing only if your gun manufacturer confirms the fit and stud size.
Buyer Feedback and Practical Expectations
Buyer experiences with small welding accessories often depend on compatibility, setup, and expectations. A user replacing the correct Uni-Spotter tip will likely judge this part differently than someone who expected a universal tip for any welding gun.
For the best outcome, verify the exact gun model, stud size, and repair task before buying. That single step prevents most common mistakes with replacement welding tips.

Who should skip this tip?
Skip it if you do not own a compatible Uni-Spotter stud gun, need a complete welder kit, or use studs larger than 2.6 mm. You should also skip it if your repair task calls for a different Uni-Spotter tip style.
The Bottom Line
The H and S Auto Shot 1004 is a practical replacement tip for users who already work with compatible Uni-Spotter stud welding guns and studs up to 2.6 mm.
