The world's first easy conversion between tabletop and handheld.
From the creative mind of Ascent engineers — the QCW fiber laser tabletop replaces the YAG laser. Designed to make channel letters from aluminum, stainless steel, galvanized steel, and brass, it handles aluminum up to 0.063" and stainless steel up to 0.040".
See it in action
Built for the sign industry
Ascent tabletop laser welders with CCTV / CCD camera monitoring systems are essential tools in the sign-making industry. They let you accurately fuse 3D channel letter faces or bases to their side returns without distorting thin metal coils.
Working at tight angles and tiny letter strokes requires a real-time CCD monitor to ensure flawless alignment of your focal laser spot. The CCD camera puts the weld zone on a high-precision touchscreen, so you can line up narrow letter corners safely and precisely — every time.
YAG vs. QCW: which tabletop welder is right for channel letters?
When choosing a tabletop welder for channel letters, your primary decision is between two laser types:
- YAG lasers — struggle with aluminum.
- QCW lasers — offer high peak power, continuous / pulse flexibility, and excel with aluminum.
For aluminum channel letters, QCW is the clear winner.
What a specialized channel-letter welder needs
The best tabletop laser welders built for advertising and signage share three features:
- Flat glass working surface — prevents scratching glossy metal coils.
- Micropositioning rods — for precise, repeatable placement.
- Dedicated CCD monitor — for safely aligning narrow letter corners.
The Ascent QCW tabletop / handheld hybrid
This innovative hybrid system easily converts between a dedicated tabletop jig welder and a handheld gun — the world's first to do so.
It uses quasi-continuous wave (QCW) fiber technology, enabling a 300W beam to deliver pulse peaks equivalent to a 3000W continuous laser. A QCW laser runs in high-peak-power pulse mode, providing peak power up to ten times its average power. It's highly optimized for the narrow strokes of channel letters, processing aluminum up to 0.063" and stainless steel up to 0.040", with a minimized heat-affected zone that protects painted coils.
Why QCW fiber?
- 300W QCW is equivalent to 3000W of other laser types.
- Pulse laser beam — ideal for the narrow strokes of channel letters.
- Minimized heat-affected zone (HAZ) — the laser delivers energy in pulses, letting the material cool between pulses. Reduced thermal input means no distortion on thin materials and painted coils.
- Works with painted coils — the minimized HAZ leaves the finish intact.
- Easy to convert between tabletop and handheld use.
- User-friendly — optimal results can be mastered quickly, with minimal training.
