Combination of tabletop and handheld

The best solution for small to medium channel letters

The world's first

Easy conversion between a tabletop and handheld. Designed for aluminum up to 0.063" and stainless steel.

From the creative mind of Ascent engineers comes Fiber laser tabletop to replace YAG laser. Designed to makes channel letters from aluminum, stainless steel, galvanized steel and brass.

QCW (Quasi-Continuous Wave) laser welding is a technique that utilizes a high-peak-power laser to weld materials using short pulses. This method offers several advantages, including a minimized heat-affected zone and greater flexibility compared to continuous wave (CW) laser welding. A QCW laser can operate on high-peak-power pulse modes, providing peak power up to ten times the average power.

Advantages of QCW laser welding

  • 300W is equivalent to 3000W of other laser types.
  • Features a pulse laser beam, ideal for the narrow strokes of channel letters.

Minimized heat-affected zone (HAZ)

QCW lasers deliver energy in pulses, allowing the material to cool between pulses. This approach reduces thermal input and minimizes the heat-affected zone. Suitable for thin materials.

The reduced thermal input makes QCW welding ideal for thin materials, where excessive heat can cause distortion or damage. It is suitable for aluminum (from 0.020" to 0.063") and stainless steel (up to 0.040"). Additionally, it can be used with painted coils.

Skills: Achieving optimal results with QCW laser welding can be mastered quickly.

How about laser safety?
For laser welders, we recommend using special safety glasses or a laser helmet, which we supply with the machines. Use welding gloves, or you can purchase special gloves and an apron that withstand temperatures over 5000 °F. For laser welders, use laser partitions that can be purchased from us or make your own. For the laser cutter, ensure it is purchased with a cover, or use laser partitions available from us, or make your own. For the laser cutter, ventilate fumes to the outside or purchase a special filter.
