Amada Laser Technical Support & Service

For bright, oxide-free edges on stainless steel, use high-purity nitrogen (99.95%+) as the assist gas at pressures between 12-20 bar depending on thickness. Key parameters to adjust: focus position (start at 0 and adjust in 0.5 mm increments), cutting speed (slightly below the maximum to improve edge smoothness), and nozzle standoff distance (typically 0.5-1.0 mm). If you see yellow discoloration, increase nitrogen pressure or check for gas line leaks. Our application engineers can provide parameter sheets specific to your stainless grade and thickness upon request.

Mild/carbon steel: oxygen (O2) for oxidation-assisted cutting. Produces a dark oxide edge but allows faster cutting on thick material. Stainless steel: nitrogen (N2) for clean, oxide-free edges. Aluminum: nitrogen at high pressure. Brass and copper: nitrogen or compressed air depending on edge quality requirements. Some shops use compressed air for thin mild steel to reduce gas costs, though edge quality is slightly lower than oxygen-cut edges. We can recommend the optimal gas and pressure for your specific material mix.

The standard 2-year warranty covers the laser source, CNC controller, servo motors, linear guides, and cutting head assembly against manufacturing defects. It does not cover consumable items (nozzles, protective lenses, ceramic rings), damage from misuse or power surges, or wear items like bellows. The laser source carries the manufacturer's original warranty (IPG: 2 years, Raycus: 18 months standard / 2 years extended). Extended warranty and maintenance contracts are available for purchase separately.

Common consumables (nozzles, protective lenses, ceramic rings, focus lenses) ship within 24-48 hours from our regional stocking warehouses in the US and Europe. Less common components such as servo drives, control boards, and cutting head assemblies typically ship within 3-5 business days. We recommend keeping a starter kit of consumables on hand to avoid any production interruption. Our parts team can recommend the right inventory level based on your production volume and material mix.

Yes. For issues that cannot be resolved remotely, we dispatch field service engineers to your facility. On-site service is available in most regions through our network of 20 regional service centers and 60+ authorized distributors. Response time varies by location but is typically 2-5 business days for non-emergency visits. Emergency on-site support can be arranged for production-critical situations. Installation and commissioning are included with every new machine purchase at no additional charge.

This depends on your material mix and thickness range. Fiber lasers (1,070 nm wavelength) are faster and cheaper to operate for metals under 20 mm, drawing up to 70% less power than CO2 systems at equivalent output. They handle reflective metals like copper and brass that CO2 lasers (10,600 nm) struggle with. On the other hand, CO2 lasers still produce smoother edge finishes on thick acrylic, wood, and certain plastics — materials that fiber lasers cannot process effectively due to wavelength absorption characteristics. For mixed-material shops cutting both metals and non-metals, some operators maintain both technologies. If your work is 80%+ metal, fiber is the more economical choice today. If non-metallic cutting is a significant part of your volume, CO2 remains relevant despite its higher operating costs ($15,000-$25,000/year in gas and mirror maintenance vs. near-zero for fiber consumables on the optical path).

Enclosed (Class 1) machines confine the laser beam, reflected light, and fumes inside a protective cabin. This satisfies most workplace safety regulations without additional infrastructure and allows the machine to run adjacent to other workstations. The tradeoff: loading oversized or irregular workpieces is more constrained, visual monitoring during cutting requires cameras or viewing windows, and the enclosure adds to the machine footprint and cost (typically 10-15% more than an equivalent open-frame unit). Open-frame machines offer easier access for large or heavy sheet loading and direct visual inspection, but require a dedicated safety zone with laser safety curtains or walls, fume extraction hoods positioned above the cutting area, and mandatory laser safety eyewear for all personnel within the zone. CE and FDA regulations generally require Class 1 enclosure for new installations unless a documented safety assessment justifies an open configuration with equivalent protective measures.

Fiber lasers at 1,070 nm wavelength are not suitable for cutting non-metallic materials such as wood, acrylic, leather, fabric, or most plastics — these materials do not absorb the fiber wavelength efficiently and either fail to cut or produce hazardous fumes (PVC in particular releases chlorine gas). Carbon fiber reinforced polymer (CFRP) can be cut but produces toxic particulates requiring specialized filtration. Highly reflective metals like polished copper sheets above 6 mm can cause back-reflection damage to the laser source if the machine lacks a back-reflection protection module — most modern fiber lasers include this, but confirm before processing. Titanium cuts well but requires argon shielding gas instead of nitrogen or oxygen to prevent embrittlement, adding gas cost. These are hard limits of the technology, not quality issues that can be tuned away with parameter adjustments.

Standard configurations (3015/4020 series, 1-12 kW) are typically ready to ship within 15-25 days from order confirmation. Custom configurations, large-format machines (6025), or high-power units (20 kW+) may require 30-45 days depending on component availability. Shipping transit time by sea is approximately 25-35 days to North American and European ports. Air freight is available for urgent orders at additional cost. We provide container loading photos and tracking information once the machine ships.

Yes. Send us your material samples (specify grade, thickness, and any critical tolerances) along with your DXF or DWG cutting files. We will run the parts on the machine model you are considering and return the cut samples to you along with the parameter settings used. There is no charge for this service. It takes approximately 5-7 business days from receipt of your materials. This lets you evaluate edge quality, dimensional accuracy, and heat-affected zone characteristics before making a purchase decision.
