Fiber Laser Cutter Installation Requirements Checklist
Use this page to validate your workshop before delivery: space & access, foundation, utilities (power/grounding), assist gas, ventilation, rigging/unloading, and commissioning. Values and constraints referenced from GA Series user manual and may vary by exact model & local codes.
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.
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.

Watch the GA Series customer feedback and workflow context.
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.
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
- Grounding resistance should be <4 Ω.
- Ground needles: total ≥3; material pure copper or galvanized; diameter ≥15 mm; length ≥1.5 m (set about 1 m away from machine).
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. |
| Leakage protection note | Recommend air switches without leakage protection; if used, leakage current ≥300 mA (recommended >500 mA) | To reduce 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 |
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.
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.
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.
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.
