Rough edges on stainless steel are typically caused by incorrect assist gas pressure (too-low nitrogen), incorrect focal position, or a contaminated protective lens. Check nozzle alignment, increase nitrogen to 12–18 bar, and inspect the protective window for debris or damage.

Dross usually means your cutting speed is too high, assist gas pressure is too low, or focus position is off. On thick mild steel with oxygen, dross often indicates too much power at low speeds. Try reducing speed 10–15% or increasing oxygen pressure slightly and re-test.

Inspect daily and replace every 1–4 weeks depending on material type and hours. Cutting galvanized, coated, or reflective metals degrades lenses faster. Keep 5–10 spares in stock to prevent production downtime.

Start with the safety interlock loop: 1) Check chiller water flow sensor (a stuck magnetic plunger is the #1 cause), 2) Confirm all doors are fully closed, 3) Check E-stop status, 4) Read fault codes on the controller. About 90% of no-fire cases are safety interlocks working correctly, not a laser failure.

Yes — we fully support Han's Laser, Bodor, and Raytools fiber laser cutting machines. Our Canadian technicians can assist with service, consumables, troubleshooting, and parts. We can also service other fabrication machinery — submit a Service Request describing your machine and issue and we will advise on the fastest path.

Nitrogen is the recommended gas for aluminum — it prevents oxidation and delivers clean, bright edges. Use high-purity nitrogen (99.99%+) at 10–18 bar depending on thickness. Avoid compressed air on aluminum as it causes oxidized, rough edges with significant dross.

Fiber laser welders can join stainless steel, mild steel, galvanized steel, aluminum (with proper settings), copper, brass, and titanium. They are especially effective for dissimilar metal joining. Reflective metals like copper require specific power settings to avoid back-reflection damage to the laser source.

Blackening or burning indicates too much power, insufficient shielding gas, or too-slow travel speed. Increase travel speed, reduce power by 10–15%, and ensure argon or nitrogen shielding gas is flowing at 15–20 L/min with the nozzle correctly positioned over the weld pool.

Yes. Handheld laser welders are Class 4 laser devices and require proper laser safety training, appropriate PPE (laser safety glasses rated for your wavelength and power level), and awareness of skin and eye hazard zones. Rise Tek provides operator training as part of every machine sale.

Bend deduction = 2 x Setback minus Bend Allowance. Most press brake CNC controllers (Delem DA66T, ESA S660) calculate this automatically when you input material type, thickness, punch tip radius, and V-die opening. For manual calculation, use the K-factor method with published tables for your material.

Inconsistent bends are typically caused by: 1) Material thickness or hardness variation within the sheet, 2) Worn punch or die tooling, 3) Crowning compensation not calibrated for the load, 4) Hydraulic oil temperature fluctuation. Check your crowning system, inspect tooling for wear, and verify your die is level and properly seated.

Standard rule: V-opening equals 6–8 times material thickness. For 3mm steel use an 18–24mm die. For 8mm+, use 8–10x thickness. Tighter dies produce smaller inside radii but require significantly more tonnage and can crack high-tensile materials.

Rise Tek Machinery sells and fully supports Han's Laser fiber laser cutting machines (HF Expert, HF S Smart, HF Mini S sheet cutting; TX and PD tube cutting series), Bodor fiber laser cutting machines, Raytools cutting heads, and Dener and Inanlar CNC press brakes. Full parts, service, and training support included.

Yes — Rise Tek is one of the few Canadian dealers that actively supports Bodor fiber laser cutting machines. We can provide service, consumables, protective lenses, and remote or on-site troubleshooting. Submit a service request with your Bodor model and fault description and our team will respond within 1 business day.

In many cases, yes. Our technicians have experience across a wide range of fiber laser and press brake platforms. If you have a machine not listed here, submit a Service Request with your brand, model, and the issue you are experiencing — we will let you know what support we can offer.

Rise Tek Machinery is an authorized Canadian dealer for Han's Laser — one of the world's largest fiber laser manufacturers. We sell and fully support the HF Expert, HF S Smart, HF Mini S (sheet cutting) and TX/PD Series (tube cutting) machines. We also sell and service Bodor fiber laser cutting machines and Raytools cutting heads.

Cutting up to 6mm mild steel and 4mm stainless: 1.5–3kW is sufficient. For 6–12mm mild steel and 6mm stainless: 4–6kW. For 12–25mm mild steel and stainless up to 12mm: 8–12kW+. We almost always recommend buying one power tier higher than your current material requirements to future-proof your investment.

Han's Laser is the world's #2 fiber laser manufacturer by volume and delivers cutting quality that competes with European brands at significantly better price points. As an authorized Canadian dealer, Rise Tek provides full installation, operator training, warranty service, and ongoing parts and consumables support — everything you need to keep your machine producing.

Bodor machines offer a strong price-to-performance ratio, with IPG or Raycus laser sources, solid motion systems, and user-friendly CypCut controls. Rise Tek provides Canadian sales and service support for Bodor, meaning you get a reliable machine backed by local expertise — not just a remote manufacturer overseas.

Yes. Rise Tek sells Dener and Inanlar CNC press brakes and provides full Canadian installation, operator training, programming support, and ongoing service. Both brands offer European-quality hydraulic CNC press brakes with modern Delem or ESA controllers, backed by our Mississauga-based team.
