Fiber Laser Cutter Installation Checklist: Site, Power & Gas

Q: What gas purity is recommended for oxygen and nitrogen cutting?

Reference: oxygen purity >99.6% and nitrogen purity ≥99.99%. Flow/pressure planning depends on laser power, material mix, and production strategy.

How to use this checklist

Treat this as a “work order” for your facilities team and an “acceptance gate” for procurement: everything marked Must-have should be done before the machine arrives.

Scope and safety notice

This checklist summarizes common planning requirements for selected GWEIKE enclosed exchange-table machines, including GA Series configurations. Electrical supply, grounding, foundation, gas, extraction, lifting and safety requirements vary by model, laser power, destination and local regulations. Always use the final model-specific installation drawing, electrical diagram and user manual. Work must be reviewed by qualified electrical, gas, structural, rigging and safety professionals.

If the machine configuration has not been finalized, use the fiber laser cutting machine buyer's guide before preparing the final site plan.

Model-specific drawings still matter

GA models (3015/4020/6015/6020/6025/8025) have different footprints and anchor layouts. Use this checklist for the common requirements, then confirm the final foundation drawing for your model.

Don’t “assume” utilities

Most commissioning delays come from missing gas regulators, wrong water type, or unstable power. Lock these in at least 2–3 weeks before delivery.

GA Series Fiber Laser Cutter Installation Requirements Checklist

Phase 0: Before delivery (access & route)

Plan the machine’s route from truck → door → final bay. Confirm clearances and overhead constraints.

Route & access checks

Confirm door opening size, pillar height, cable holder height, and whether the road surface can support armored rollers/rigging.
Pre-plan any floor works (slitting/punching etc.) per the basic plan before the machine arrives.

Tip: If you have tight doorways or low overhead beams, do a “dry run” with your rigging contractor using the final footprint drawing.

Phase 1: Space planning & environment

Minimum service clearance

Keep enough room for maintenance access, exchange table movement, and safe material handling.

Leave ≥1.2 m at the left and rear sides of the machine tool.
Keep the laser and water chiller ≥1.0 m from the wall.

Environmental constraints

Use a site with good ventilation; avoid dust/corrosion/pollution/water leakage; recommended ambient temperature +5°C to +45°C.
Avoid thermal deformation from one side in direct sunlight and the other side in wind (consider louvers if near windows).
Avoid strong electromagnetic interference sources (arc welding, EDM) near control/servo units.

Phase 2: Floor & foundation requirements

Floor performance (baseline)

Ground flatness: ±10 mm.
Concrete thickness under bed & legs: ≥200 mm; compressive strength ≥30 N/mm²; load >30 kN/m².
Foundation installation should avoid large vibrations; if present, drill a shock ditch.

Embedded steel plates & anchors (example method)

Embed steel plates at ground level; steel plate thickness ≥20 mm, size 200×200 mm.
Example anchor method uses expansion bolts M12×100 (quantity shown as 64 in the example instruction).
Some sites may pour concrete columns (example size 400×400×600) for base anchors; strong cement surfaces may be used directly as foundation.

Engineering note: Always validate against your local building codes and the final GA model foundation drawing.

Phase 3: Power quality & grounding

Electrical supply & quality

Electrical spec reference: Three-phase five-wire, 380V 50Hz (frequency may vary by model).
Power quality: three-phase unbalance <2.5%, line voltage fluctuation <5%; single-phase 220V ±5%.
Use a regulated power supply for machine/laser stability; avoid routing air compressors/fans through the regulator.

Grounding requirements

The GA Series manual provides a reference target of <4 Ω and an example ground-electrode arrangement.
The final grounding method must be designed and tested by a qualified electrician according to the machine electrical diagram, facility grounding system, soil conditions and local electrical code.
Do not treat the example number, dimensions or placement of ground electrodes as a universal grounding design.

Typical procurement list (reference)

Below items are commonly prepared before installation (air switches, stabilizer size, power cord spec, etc.). Confirm with your final laser power and local electrician.

Item	Reference spec	Notes
Distilled/Purified water	18 L/barrel; chiller water volume: 1–1.5 kW: 15 L; 2–3 kW: 25 L; 4–6 kW: 50 L	Mineral water prohibited.
Machine air switch	4P/AC380V; 1–2 kW: 63A; 3–6 kW: 80A	Reference values.
Voltage stabilizer	AC380V; 1–4 kW: 30 kVA; 6 kW: 50 kVA	Reference values.
Main power cord	5P; 3–5 m; cable spec: 1–2 kW: 6 mm²; 3–4 kW: 10 mm²; 6 kW: 16 mm²	Reference values.
Electrical protection	Select circuit breakers, disconnects and residual/ground-fault protection according to the final machine electrical diagram and local code.	Confirm ratings and protection coordination with a qualified electrician. Do not remove or bypass required protective devices to prevent nuisance trips.

Phase 4: Assist gas standards & piping

Gas purity & supply logic

Oxygen: purity >99.6%; if using liquid oxygen, add vaporizer; example output pressure 1.0 MPa and flow 1.0 m³/min (reference).
Nitrogen: purity ≥99.99%; if using liquid nitrogen, add vaporizer; example output pressure 2.0 MPa; flow reference: 1.5 m³/min (≤3 kW) / 2.2 m³/min (>3 kW).
Air cutting: requires pure and dry high-pressure air; max air pressure 3.0 MPa.
Do not use gas cylinders completely; keep residual pressure (at least one atmosphere above air pressure) and replace gas when oxygen pressure is low to avoid alarms.

Regulators (reference)

Regulator	Reference spec
Nitrogen pressure reducing valve	Input ≥15 MPa; Output 0.2–3.0 MPa
Oxygen pressure reducing valve	Input ≥15 MPa; Output 0.05–1.2 MPa

Gas-system safety

Gas storage, vaporizers, regulators, pressure-relief devices and piping must be selected and installed by qualified gas-system professionals. Use components approved for the gas, pressure and destination regulations. Never use oxygen-incompatible lubricants, seals or contaminated fittings. All pressure and flow values on this page are GA Series planning references.

Implementation tip:

For higher power or heavy nitrogen usage, many factories move from cylinders to liquid tanks + vaporizers or on-site nitrogen generation. Confirm your “assist gas strategy” during quoting so facilities can prepare early.

Phase 5: Cooling water & winter prep

Water type

Cooling circulating water requires distilled water or purified water; mineral water is prohibited.

Below-freezing protection

When ambient temperature is below 0°C, use antifreeze (ethylene glycol or polypropylene glycol); alcohol/corrosive antifreeze is prohibited.

Best practice: Put “winter procedure” into your SOP (who drains, who replaces, who verifies chiller operation during power interruptions).

Phase 6: Ventilation, fume extraction & fire safety

Ventilation & extraction

Exhaust gas generated during cutting is harmful; ensure dust suction device is operating normally and the working site is ventilated.

Fire safety

Processing site should be equipped with appropriate fire extinguishers and reserve certain fire exits.
Oxygen cutting increases fire risk; remove flammable/explosive materials and maintain preventive facilities.

Operator safety reminder:

The internal laser source may be Class 4, while the complete enclosed machine may have a different accessible-emission classification during normal operation. Follow the classification label, safety manual and interlock requirements supplied with the exact machine. Maintenance or interlock-bypass work must be restricted to trained and authorized personnel.

Phase 7: Unloading & rigging tools

Prepare lifting and handling tools in advance. If your model is larger (e.g., 6025/8025), upgrade lifting capacity accordingly.

Lift-plan requirement

Crane and forklift capacity must be selected from the packed weight, lifting points, center of gravity, lifting radius and rigging plan for the delivered machine. The 10 t and 15 t figures below are early planning references only, not a substitute for a lift plan prepared by the rigging contractor.

Required tools (reference)

Truck crane recommended ≥10 t lifting capacity (higher if boom needs are larger).
Forklift capacity 10 t; bridge crane bearing capacity 10 t.
At least 2 hydraulic jacks with lifting force ≥5 t (min height setting 30 mm); armored rollers; crowbar extensions.
If model is LF6025GA/LF8025GA, prepare 15 t lifting equipment.

Handling precautions

Do not place the machine on the floor without a bottom plate; keep bottom plate <100 mm from ground during movement.

Phase 8: Unpacking, installation & trial cutting

Unpacking & incoming inspection

Check product type, damage during transport, completeness of components; contact supplier if mismatch/missing/damage.

Typical engineer scope (what to expect)

Level adjustment; water chiller installation; fiber optic installation; cutting head installation; gas connection; fan installation.
Power-on test: external voltage, origin/limit switch tests, axis homing, chiller & fan power-on.
Trial cutting: air opening, red light check, nozzle adjustment, calibration/edge finding, parameter setting, cutting.

Acceptance gate: Don’t accept “it runs” — accept based on repeatable cut quality on your real parts/materials + stable alarms/pressure/temperature behavior.
