Lampert PUK 6 TIG Welder: 10 Frequently Asked Questions

The Lampert PUK 6 is a high-precision TIG welder engineered for professional jewellery work. It offers jewellers a powerful solution for delicate welding tasks, with accurate control, minimal heat spread and the flexibility to handle various metals and techniques. Below are answers to the most common questions customers have about this precision tool.

1. What makes the PUK 6 different from traditional soldering?

Traditional soldering uses direct flame, high heat and flux, which can distort delicate components or damage heat-sensitive gemstones. The PUK 6 uses micro-welding pulses to produce clean, strong welds with pinpoint accuracy and minimal heat spread. This ensures fine details stay intact and the surrounding materials are protected—no solder or flame required.

2. What types of metals can the PUK 6 weld?

The PUK 6 is compatible with a wide range of metals, including:

• Gold
• Silver
• Platinum
• Palladium
• Stainless steel
• Titanium
• Nickel and tin alloys

Its versatility makes it ideal for a variety of jewellery applications.

3. Is the PUK 6 suitable for beginners?

Absolutely. The PUK 6 includes intuitive presets developed in real workshops, making it accessible for newcomers. Its user-friendly interface allows beginners to achieve clean, professional results with minimal training, while still offering the advanced capabilities that experienced jewellers expect.

4. How does the PUK 6 welding process work?

The PUK 6 generates an electric arc through a tungsten electrode. When the workpiece contacts the electrode tip, a high-energy pulse is released to fuse the metal. Argon gas is used as a shielding gas to prevent contamination and oxidation, resulting in a clean, controlled weld. Lifting the workpiece away instantly stops the process—no foot pedals or extra tools required.

5. Does the PUK 6 generate excessive heat?

No. In fact, its minimal heat impact is one of its biggest advantages. The PUK 6 applies focused heat only where it’s needed, making it ideal for thin metals, filigree, and jewellery with gemstones. This reduces the risk of distortion and preserves delicate details.

6. What are the key features of the PUK 6?

• High-resolution touchscreen (70% higher clarity)
• Standby mode to cut energy use by 85%
• Up to 3.3 weld spots per second
• Ultra-short pulses (as short as 0.1 ms)
• Capability to weld metals as thin as 0.2mm
• Clean, precise weld spots with improved control and finish

7. How does the SM6 Microscope enhance welding?

The included SM6 Microscope provides:

• 10x magnification and 20mm field of view
• UV and IR eye protection via LCD shielding
• Adjustable hand rests to reduce fatigue
• LED lighting with four brightness levels for clear visibility
• Height and tilt adjustments for ergonomic comfort

Together, these features ensure welders can work comfortably and accurately, even during long sessions.

8. What is the Lampert PUK not suitable for?

While ideal for precision tasks, the PUK 6 is not designed for large-scale welding or thick, industrial metalwork. It is also not a full replacement for soldering in applications that require broader heat distribution. For very heat-sensitive materials, it’s best to conduct a test weld before working on high-value items.

9. Does the PUK 6 come with a warranty?

Yes, the PUK 6 comes with a 3-year warranty. Please note that the handpiece is not covered under this warranty. For more information click here.
