How to buy correct laser tube for your laser cutting machine-Five Laser Technology CO., LTD

There are more than thousands of laser cutting / engraving machine suppliers in the world, but there is no universal standard to define a laser tube power. Even for same size laser tube, different suppliers could tell you different laser power. For example, laser tube with length 1200mm and Diameter 50mm, actually most suppliers say it is 60w, and some suppliers say it is 65watt, 70watt, even 80watt. Thus it happens a lot some customers don’t get a correct laser tube, it can be size problem, or the new tube cannot cut as thick material as the old one, or the new laser tube is too long to put inside of the old laser cutting machine

We knew that there are 2 very important parameter for CO2 glass laser tube: Rated power, Peak power. For example laser tube with length 1250mm and diameter 80mm, the rated power commonly 90w, but peak power can be 100w, even 110w. Some laser machine supplier told buyer the peak power directly, not rated power of laser tube. It means some laser supplier sell laser tube by rated power, some laser supplier sell laser tube by peak power directly, that's why big misunderstanding during buying laser tube by user

If you bought a longer laser tube than former one, maybe it can not be put inside of machine body

We, Five laser company, as one of the professional co2 laser parts supplier in China, deeply know that the laser tube power is defined when the tube length and diameter are assured in production.

The easist way for customers to tell the laser tube power is by tube length and diameter. You could just choose the new tuee same length and same diameter with your old tube on laser machine, then the laser power commonly will be similar with your old one. This saves you much time and avoiding trouble if wrong spec

Model	Rated power(w)	Peak Power (w)	Length (mm)	Diameter (mm)
50w	50	50~70	1000	50
60w	60	60~80	1200	50
70w	60	60~80	1250	55
80w	80	80~110	1600	60
90w	90	90~100	1250	80
100w	100	100~130	1450	80
130w	130	130~150	1650	80
150w	150	150~180	1850	80

Different manufacturer produces laser tube with different peak power.

1. 50w co2 laser tube, length 1000mm, diameter 50mm

2. 60w co2 laser tube, length 1200mm, diameter 50mm

3. 70w co2 laser tube, length 1250mm, diameter 55mm

4. 80w co2 laser tube, length 1600mm, diameter 60mm

5. 90w co2 laser tube, length 1250mm, diameter 80mm

6. 100w co2 laser tube, length 1450mm, diameter 80mm

7. 130w co2 laser tube, length 1650mm, diameter 80mm

8. 150w co2 laser tube, length 1850mm, diameter 80mm

Above technical spec of laser tube for your reference, different laser tube factories such as RECI laser, EFR, Yongli, SPT, CDWG, SP, Puri may have little difference in length or diameter in same laser power level, but it's not big problem for buying. For example commonly 90w laser tube length by SPT is 1250mm length, but RECI laser tube 90w will have 1200mm. If still any doubt on laser tube buying you can reach us by email: info@fivelaser.com
