BSG-668 vs. BSG-568 – Which Butane Soldering Iron is Right for You?

When it comes to choosing a butane soldering iron, two of the most popular options from Berkling Tools are the BSG-568 and the BSG-668. Both are versatile, portable, and designed for users who value cordless convenience—but there are some key differences that can help you decide which model is the right fit for your needs.

 

What They Have in Common

• 3-in-1 Functionality: Both models function as a soldering iron, micro torch, and heat blower.
• Portable & Cordless: Powered by butane gas, they work anywhere—no cords or outlets needed.
• Fast Heat-Up: Heats up quickly and is ready to use within seconds.
• Built-In Stand & Protective Cap: Both include safety features for resting and storing the tool.

Fuel Capacity and Runtime

If you need to work longer without refueling, this matters. The BSG-568 runs up to 90 minutes with its 18ml tank. The BSG-668 holds 22ml and lasts about 125 minutes.

✅ Winner for longer runtime: BSG-668

Soldering Tip Performance

This is where the difference really shows. Both models use copper brass tips, but the BSG-668's tip is multi-layer plated—iron, nickel, and chromium—with a final tin coating. That means better heat transfer, smoother soldering, and more resistance to corrosion.

The BSG-568 features a nickel-plated copper brass tip—sufficient for general use but not as durable or efficient at holding heat.

✅ Winner for performance and durability: BSG-668

Size and Handling

The BSG-568 is more compact and lighter, making it great for portability and quick fixes. The BSG-668 has a bit more weight, offering better control for precision work.

✅ Winner for portability: BSG-568
✅ Winner for stability and control: BSG-668

Included Accessories

Both models include:

• A built-in metal stand
• A protective cap

The BSG-568 also includes a mini wrench and a second soldering tip for added value.

✅ Winner for accessories: BSG-568

Which Butane Soldering Iron Should You Choose?

• Pick the BSG-568 if you're a hobbyist or need a light-duty, budget-friendly cordless soldering iron.
• Go with the BSG-668 if you're looking for professional performance, better tip quality, and longer runtime.

⚠️ Important Note:

This unit does not come pre-filled with butane gas. You will need to purchase butane separately.

Final Thoughts

Both the BSG-568 and BSG-668 are excellent choices when it comes to cordless butane soldering irons. Your choice comes down to how often you’ll use it and what kind of performance you expect. Either way, you're getting a high-quality tool backed by Berkling’s commitment to reliability and innovation.
