Portable Laser Welding Head SUP21T
The SUP21T is designed for workshops that require high productivity while maintaining maneuverability. An evolution of the Series 20, this model is optimized to handle laser sources up to 2000W (peaks up to 3000W in specific conditions), providing precise welding thanks to a smoother and more stable beam control system.

Technical Features and Innovations

• Ultra-light design: Lightened version enabling prolonged one-handed operation and reduced operator fatigue during long or complex welds.
• Optimized Wobble technology: High-frequency galvanometer motor enabling extremely precise beam oscillations for uniform weld beads and handling joint tolerances up to 1.5–2 mm.
• Shielded optical path: Internal layout minimizes stray light and protects collimation lenses, with mechanically aligned components to reduce thermal drift.
• Dual-circuit cooling: Independent air/gas and water channels to keep internal temperature stable during intensive high-power use.

Competitive Advantages of the SUP21T

• Focus precision: Micrometric graduated tube for smooth, accurate focal adjustment; enables transitions from thin steel (0.8 mm) to thicknesses up to 6 mm.
• 3-in-1 versatility: Supports welding, cutting and cleaning functions, making it a multipurpose tool for metalworking departments.
• Simplified maintenance: Quick replacement of the protective window and M16-threaded nozzles without complex disassembly, reducing downtime.
• Integrated safety: Built-in contact sensor and software alarm management to prevent accidental laser emissions when the torch is not in operating position.

Recommended Applications

• Light to medium fabrication: Suitable for metal furniture, frames, commercial kitchens and automotive components.
• Materials: Stainless steel, galvanized steel, iron and aluminium alloys (up to medium thicknesses).
• Compatible sources: Designed for 1.5 kW and 2.0 kW laser generators with QBH connector.

Key Difference Compared to the SUP23T
While the SUP23T targets maximum power and heavy fabrication, the SUP21T prioritizes precision and versatility for daily use, proving more maneuverable in confined spaces and for welds with complex angles.

Expert Tip
The SUP21T is suitable for positional welding (vertical, overhead): its balance reduces hand-induced vibration, often avoiding the need for post-weld finishing.

WELDING TORCH COMPONENTS (Name - Function)
Name - Function
Copper nozzle - Funnels the laser beam and shielding gas to the weld point.
Graduated tube / adjustment collar - Allows millimetric focal position adjustment.
Protective lens - Shields internal lenses from molten metal spatter and dust.
Focusing lens - Concentrates the laser into a very small, high-energy spot.
Reflective lens / galvanometer - Directs the beam; in wobble models it creates the oscillating movement.
Wobble motor - Drives beam oscillation for wider welds.
Collimation lens - Makes divergent fiber output beams parallel.
Activation button / trigger - Controls laser emission (usually with a contact safety).
Wire-feed bracket - Mechanical support for automatic filler wire insertion.
Water/gas circuits - Cool the torch (water) and protect the melt pool (gas).
Protective sleeve - Connection and protection for the fiber optic connector.
