Mastering Precision Welding: A Deep Dive into Chinacnczone's HW980 Handheld Laser Welding Gun

In the world of portable laser welding, the tool in your hand makes all the difference. 

Chinacnczone RECI 4-in-1 Handheld Welding Machine features the advanced HW980 Welding Gun – a powerhouse of innovation designed for industrial-grade precision, safety, and versatility.

Here’s everything you need to know about this game-changing tool:

Core Components & Design

The HW980 integrates high-precision optics and ergonomic controls into a compact, professional-grade gun:

1. QBH Fiber Optic Connector:
   Ensures secure, high-stability coupling between the laser source and welding head. Compatible with most industrial laser generators (up to 3000W), it features a patented locking mechanism for vibration-resistant operation.

2. Collimating Lens:
   Transforms scattered laser input into a perfectly parallel beam, essential for maintaining consistent energy density before deflection.

3. Galvo-Lens Module:
   The heart of precision! A high-speed motor paired with mirrors dynamically deflects the laser beam, enabling programmable spot shapes (dots, lines, circles) and oscillation patterns for versatile welding applications.

4. Focus Lens (F=15mm):
   Concentrates the collimated beam into a high-power-density spot. The standard lens (Ø20mm) delivers pinpoint accuracy for deep-penetration welds.

5. QuickSwap Protective Lens:
   Shields the focus lens from spatter and debris. Easily replaceable to maintain optimal beam quality and extend hardware life.

6. Modular Nozzle System:
   Copper nozzles (e.g., AS-12, BS-16) direct shielding gas and can be adjusted to change focal distance. Standard nozzle: Ø12mm, length 80mm.

7. Smart Control Panel:
   Integrated buttons for real-time parameter adjustment:

   • Power +/-

   • Oscillation width/frequency

   • "OK" confirmation

   • LED status display

Critical Procedures

1. Fiber Optic Insertion & Locking

(Safety First! Wear laser goggles during handling)

• Step 1: Align the red dot on the QBH interface with the red mark on the handwheel.

• Step 2: Remove the dust cap, match the red mark on the fiber end to the QBH’s red indicator.

• Step 3: Insert straight until fully seated. Rotate the handwheel clockwise until a "click" confirms locking.

• Step 4: Pull the handwheel up and rotate clockwise again to secure.
  → Always keep optics clean and avoid vertical insertion to prevent dust contamination.

2. Beam Focusing

• Focal Adjustment:
  Loosen the locking ring → Adjust nozzle length using scale marks → Tighten the ring.
  *Tip: "0" on the scale tube = optimal focal position for welding.*

• Spot Centering:

  • Set "Width" to 0mm in software → Enter password "2000" → Navigate to "Advanced Parameters".

  • Adjust "Optical Core Offset":

    • Lower values → Spot shifts right.

    • Higher values → Spot shifts left.

  • Calibrate until the spot is perfectly centered in the nozzle.

Why the HW980 Stands Out

• Precision Control: Galvo-driven oscillation enables complex weld paths (e.g., zig-zag, spiral) for stronger, cleaner joints.

• Tool-Less Maintenance: Modular design allows rapid lens/nozzle swaps without tools.

• Industry-Standard QBH: Ensures compatibility across laser sources.

• Ergonomic UI: On-gun controls minimize workflow interruptions.

Pro Tips for Operators

• 🔥 Always clamp the safety clip to the workpiece (welding) or gun body (cleaning/cutting) to complete the circuit.

• 🧼 Inspect the protective lens before each use – contamination causes power loss and defects.

• ⚙️ Use nozzle types strategically: AS-12 for tight corners, BS-16 for thicker materials.
