Here is a summary of my findings in regard to your laser status.
Upon my arrival with Tyler’s help we figured out that the power breaker was off, for safety consideration so the laser system will not be turned off inadvertently.
After that the laser system came on successfully.
Judging it from the red pointing laser it appeared that the rough alignment is correct.
For next I have tried to make a laser burn on a piece of paper as to see the laser mode, which is indication of its health.
At 10% setting there was no output strong enough to mark the paper.
At 20%, similar results.
Finally, after several incremental steps at 80% power setting, the outer parameter of the beam started showing up. It should have been an immediate burn in the paper at a calculated 120W output.
I have checked the laser power burns before and after the laser mirrors. After the second mirror the beam burn became weaker, so I cleaned the mirror just before it.
After that the burn mark did started to show. By the time it arrived to the focusing head (the cutting area) it was barely visible.
Also by looking at the plasma of the laser tube when it was ON, it was indicating a very weak energy level.
I did not find any refill attachment to the laser tube itself, nor the manual indicated to have any.
These type of lasers were manufactured in the US in the late 70-s. However, there were a small pressurized container attached to the side with a small zoning chamber which allowed the laser to be refilled several times with fresh gas since the laser on operation uses up the internal gases from the tube.
This is the case of your laser. It have used up the internal gas and it is not able to output any more reasonable power without refilling it or replacing it with another unit.
We can recommend two possible solution for your system:
Either a replacement laser tube (there are other makers with a longer lifetime indication) to be purchased and installed. One is recommended made by a more reputable Chinese company, Reci. They have a 130W unit.
These have local suppliers so the 30% tariff likely will not apply to them.
One of those units we could supply for you installed for $1850.00.
There is another solution, which gets more involved. It is to replace the laser with a US made industrial, commercial laser. It is manufactured by Synrad.
These are available used with various time on them. The lifetime of these units is about 15 000+ hours of ON time (when the laser actually is firing). It translates into many years of operation.
They do require a chiller also.
It could be grafted into your machine since physically they would fit inside your enclosure at the back.
Please advise of your thoughts and questions in regarding the solution to your project.
Have a very good afternoon.
How much is the Synrad laser including install? And are there any appropriate higher wattage options? (If so let me know pricing of those too).
