What Laser Welder would you recommend?

I'm really glad you posted this topic, and it's great that Chad from BTI chimed in as well. I have an older Laserstar machine, and when it's operational, it works remarkably well with minimal issues. Unfortunately, the cost to have it serviced forced me to use a torix electric welder for the past six months, and I've missed the precision of the laser. I reached out to Chad, and he confirmed that they could perform the necessary adjustments at a reasonable price. Although LaserStar machines are excellent, their service and parts costs can be quite high. I'll be making arrangements for my machine right after Labor Day. Now, I should get back to my workspace and prepare the laser for transport.

At Stuller, we conducted a detailed comparison of various laser welders. Our evaluation covered durability, power output, service capabilities, ergonomics, and additional features like MP3 player functionality.

Our findings indicated that a welder should provide a minimum of 80 joules of energy to maintain a steady workflow. While lower joule machines can still function, they tend to take longer to recharge, which can frustrate jewelers seeking efficiency. Speed is crucial; the faster tasks are completed, the sooner you can relax.

We recommend opting for a stand-alone unit rather than a desktop model for several reasons. A smaller machine compromises the power supply and cooling efficiency, making it less capable of keeping up with your demands. Some desktop models may shut down momentarily for cooling, which gives you time for a quick coffee break—though that can also be seen as a drawback!

When it comes to features and additional capabilities, most welders share a similar basic design. I recommend selecting a model that includes a pulse shaping feature, as I have personally found it quite beneficial, even though many do not utilize it. Moreover, having a mechanism to connect compressed air for cooling can be advantageous if you frequently use the welder, although it might be excessive for less intensive use. Rofin, a manufacturer with over three decades of experience in laser production, boasts several unique patents. These include aligning the laser with the crosshair, even when it’s out of focus, and the renowned 'sweet spot' related to thermal lensing in the laser cavity. While the concept of thermal lensing can be complex, it essentially ensures consistent beam power with each firing.

Our assessment revealed Rofin to be the most durable option available. We operate our welders for over ten hours a day, five days a week, and even more during the holiday season. Notably, we haven't had to retire a single welder; one department still has the very first Rofin welder sold in the United States, dating back over 13 years.

In summary, we've done our due diligence and determined that the Rofin laser welder is the best choice for our needs. The most crucial takeaway is to invest in any welder that fits your requirements! Unfortunately, no laser welders come equipped with MP3 capability—so you won't be able to listen to your favorite tunes while you work.
