When a customer asks, “I just got my new CO₂ laser tube. How do I know if it’s good before I install it?” — that’s actually a smart question. A CO₂ laser tube isn’t just another spare part; it’s the heart of your laser cutting or engraving machine. Checking it properly at the start saves you from wasted time, power loss, or even machine damage later.

Let’s walk through the key steps.


Step 1. Inspect the Package Before Opening

First things first — check the box. Was it delivered with visible damage, dents, or holes?

We once had an Indian customer who noticed the outer carton corner was smashed. He contacted us immediately. Good move — because inside, the foam was slightly crushed. Luckily, the glass was fine. Always check before signing the delivery note. If the box looks suspicious, take photos.


Step 2. Unbox and Check the Glass Tube

Once you open it, gently remove the CO₂ laser tube. Look closely:

Any cracks, scratches, or chips on the glass?

Is the output window clean and scratch-free?

Is the protective cap on the lens still in place?

Remember, a small crack today can become a big problem tomorrow once the tube heats up.


Step 3. Confirm Accessories and Fittings

Every laser tube shipment should include the right extras: brackets, rubber pads, wiring, or clamps. Missing parts may sound small, but without them, you can’t mount the tube safely.

At Puri Laser, we always double-check with a factory packing list. If anything is missing, we send replacements fast — because we know downtime hurts your business.


Step 4. Check the Tube Label and Specs

Don’t ignore the details on the label. Check that:

Model and power match your order.

Production date is recent. (Why? Because CO₂ laser tubes have a shelf life.)

Factory logo and quality marks are clear.

If the label looks blurred or fake, be cautious — many cheap tubes are re-labeled in the market.


Step 5. Do a Simple Pre-Installation Test

Before installation, you can test basic things without running full power:

Shake the tube gently (just a small tilt). Hear liquid inside? That’s normal. No sound? Could mean a problem.

Inspect the electrodes and wiring points — are they clean and solid?

Connect the water cooling system briefly and check for leaks.

Don’t run high voltage until everything is in position. A rushed test is how many users burn a brand-new CO₂ laser tube.


Why Factory Checks Matter

As a CO₂ laser tube factory since 2009, Puri Laser does strict power testing before shipment. Every tube is powered on, beam quality measured, lifespan simulated. That’s why customers from the Middle East and South Asia keep coming back — they’ve told us our tubes last longer and cut more stable compared to what they used before.


Final Checklist Before Use


✅ Package arrived safe, no visible damage

✅ Glass tube clean, no cracks

✅ Output lens protected

✅ Accessories complete

✅ Label matches your order

✅ No leaks, electrodes in place


If all looks good, then you’re ready to install.

A Note on After-Sales Support

Here’s the difference: when you buy from a random distributor, once the tube fails, you’re stuck. With Puri Laser, you’re backed by the factory. If your CO₂ laser tube has issues — from shipping damage to installation problems — we provide replacement or technical guidance fast. That’s why working directly with a CO₂ laser tube manufacturer makes sense.
