CO2 laser tube refill with measurement report for UK businesses

Signs that your laser tube is losing power

• Cuts need two passes instead of one.
• Edges burn because you have to run the machine slower.
• Power fluctuates and engraving becomes uneven.
• The source is hard to start from cold, or the machine runs with no laser output.

A tube that no longer cuts 4 mm plywood in one pass often still delivers 70 to 80 % of its rated power. Check mirrors, lens and alignment first: dirty optics cause the same symptoms – our maintenance and repair service can help.

Refill or 1:1 exchange – which suits you?

Refill of your own source – measured, refilled with the original gas mixture (CO2, nitrogen, helium) and measured again. Turnaround: 3 to 7 working days.

1:1 exchange from stock – a compatible, tested source ships within 24 hours if in stock, at the same price as a refill; your old source comes back to us. We stock most common sources, including the Synrad Firestar f201 and f400.

What happens in the workshop – 8 steps

1. Incoming test and power measurement
2. Diagnosis with residual gas analysis by mass spectrometer
3. Vacuum and leak test with helium
4. Refill with the original gas mixture
5. Resonator and optics check
6. RF/HF electronics check
7. Alignment
8. Final measurement of power and beam profile

On RF sources, power supply, driver and cooling are measured before opening, and tightness is monitored under vacuum for several hours. You receive a report with the values before and after the refill, including the electrical parameters.

CO2 laser sources we refill

Synrad sources are also fitted in Videojet, Domino, Markem-Imaje, Macsa and many other machines. Laser-Store24 is an independent service provider and not an official service partner of these manufacturers; our warranty is not a manufacturer's warranty. Trademarks belong to their owners.

How much does a CO2 laser refill cost?

• €490 to €11,900 net, depending on manufacturer, model and power.
• Fixed price after measurement – nothing happens without your approval.
• If a source cannot be refilled, you are not charged for a refill and we propose a replacement.
• Prices in euros. UK deliveries are exports without German VAT; EU businesses with a VAT ID: reverse charge.

Sending your source from the UK

Pack the source so it cannot move, ideally in its original packaging. It can travel as a temporary export for repair (outward processing); UK import VAT and clearance on the way back are handled through the courier, and the return is insured. Details: packing and shipping your laser source.
