  • Coherent Laser E400 Support. Full Support

    To all of our Coherent E400 Users:

    Coherent Laser (TM) has ended the end-of-life service for Coherent E400. Coherent, as far as we are told, will still give you an exchange laser head or RF for a little more time. This repair typically takes 6 to 8 weeks, not including shipping. Coherent charges typically $23,000 for the laser head and $20,000 for the RF exchange.

    Photovac Laser continues to support Coherent E400 with full remanufacturing capability. An East Coast company is trying to regas the laser for $7000.00. Whether you like it or not, they regas the laser and send it back. Their service regas lasts for a month or so before it goes wrong; sending the laser back to them and waiting months on end is not out of the question with this company. Your end results typically your laser is not fixed, bait and switched, and your out $7000 plus shipping.

    Photovac Laser is a full-service company. We have the parts to repair the laser cavity. There are leaks within the laser cavity in most cases, and Photovac can repair these leaks with new seals, unlike any other 3rd. Party fly-by-night organization. We have RF boards, delivery optics, and pelters for power sensors. No one has these parts except the manufacturer and Photovac Laser Worldwide.

    Please contact our sales team today and ask about our comprehensive services. 1.888.349.8823 or 614.875.3300

    Thank you.

  • CO2 LASERS AND THE USE OF COOLING SYSTEMS

    Each summer, we receive dozens of lasers, RF power supplies, and DC supplies that fail due to improper cooling. Condensation is one reason for laser and premature RF failure in the summer months.

    I’m addressing my concerns to our industrial users, not so much our engraver customers. When chillers are used, room temperature and humidity must be dealt with every day. The difference in air temperature, air movement, and humidity can severely damage laser tubes, electronics, and RF supplies.

    It doesn’t matter if your RF is built into the system or is external to the system. In many cases, room temperature and humidity are not controllable. Therefore your chiller will be set to a level that doesn’t allow condensation to occur.

    Users become comfortable and fail to monitor their equipment settings daily, especially in the summer months. This year we have seen a multitude of this type of failures. Here is a simple rule to follow to help solve some of these issues. Monitor your room temperature, humidity, and dew point. The monitoring device can be purchased almost anywhere for little expense.

    Set your chiller within 5 to 7 degrees (lower) of your ambient room temperature, plus humidity level. You can get a graph to help you determine “room ambient temperature + humidity” for an actual room temperature—for example, room temperature is 86 degrees, the humidity level is 55%, and the actual room temperature will be 89 degrees. In this case, your chiller would need to be set @ 84 degrees, not 72 degrees. With air movement at 72 degrees, condensation or “dew” will generate hot electrical components, cooling plates, cooling rings, brass fittings, hose lines, etc.

    Finally, make sure your cooling equipment is up to date with clean filters, deionized water, propylene glycol, or a combination of each. Consult your manufactures manual for proper cooling requirements.

    Thanks for listening

  • Laser regas con job – Beware who you work with!

    I have written about this subject frequently about the few companies offering a regas service for your Co2 laser engraver. My first tip is to check with the Better Business Bureau in the company’s state. One company says their business is in one state, and you send it to someone else’s business and a different state. Gee, there’s a problem. And this company has kept customers’ laser and paid funds many, many times. Call, and I’ll tell you who they are. Check references, and don’t be conned when they offer cheap regas and then slap you with a $7,000 repair bill. For some years, this cheap regas con has been going on to sucker you in, and then do the old “bait and switch” is played. We have had dozens of lasers sent to us from manufacture representatives parted and pieced together. These so-called “regas” houses take good customer parts and use them to fix other customers’ lasers. I have heard this story repeatedly and have experienced the actual results many, many times. Always make sure you write down the serial # of the laser and take pictures of it. Always record the issue with the laser for your records and ours. I have had lasers sent to Photovac that were switched with other customers’ lasers to make up for these unscrupulous companies’ repairs. I’m not asking you to use Photovac Laser; I’m just asking you to do your research first and then make a well-informed business decision. Photovac Laser Worldwide has hundreds of testimonials from our customers, both past and present. We welcome you to check us out and realize Photovac does provide the best laser remanufactured laser service in the USA and worldwide. Call us today at 614.875.3300 or 1.888.349.8823.
