The advantages of dual wire feeder

  • Significant gap-closing capacity
  • Capability for multi-layer welding
  • Wide gap-filling capacity (2 x 1.6 mm wire = 2.5–3.0 mm gap-filling capacity)
  • Extremely high welding speeds
  • High deposition rate
  • Usable for both thin and thick materials
  • Easy to operate
  • Two separate wire feeders, with each wire controlled independently. When not in dual welding mode, both wire feeders can be prepared for different materials (e.g., stainless steel on one and aluminum on the other), allowing for a very short changeover time between materials.

Frequently asked

Common questions about this equipment

What does the price include? Are there hidden fees?
At Ascent Equipment, our pricing is completely transparent. The quoted price includes everything needed for operation — no add-ons, hidden fees, or extra charges. The only additional cost is freight. Included: on-site setup with professional installation and comprehensive team training; full two-year parts-and-labor warranty; ongoing software updates at no additional cost; lifetime remote diagnostics and assistance; AnyDesk Remote Desktop Software pre-installed for rapid-response remote assistance and retraining. With technicians strategically located in Buffalo, Toronto, and Kentucky, help is always nearby.
What is unique about the Ascent handheld fiber laser welder compared to others in the industry?
The Ascent laser welder is the only one in the industry that uses a refrigeration heat pump, enabling continuous operation without downtime. The laser torch is the smallest, allowing it to work in a space with a 1.5" stroke. It is the lightest in the industry, reducing operator fatigue. It is the only welder that can handle aluminum thicknesses from 0.040" to 0.27". It features a dual wire feeder for larger gaps. The machine comes as a complete set with a trolley, safety glasses, and a laser helmet.
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.
