There are as many misconceptions on laser welders as there
opinionated sales peoples. Of course Stuller loved their “full sized”
Rofin’s, they sell also them and as you guessed, they do not offer a
desktop model. I hope some actual laser owners feel inclined to voice
One comment I have is never buy a laser welder based on the maximum
joule output alone. When you bought you last car did you walk into
the lot saying just give me anything with 200 hp and that will be
fine? There are many All laser welding for jewelry requires less than
The Desktop Laser Welding Revolution!
The iWeld Series from LaserStar offers equal performance to “Full
Sized” machines. Yes, some other imported desktop welders do have
very low pulse frequency, shot limits and often need to cool down
during heavy usage, but not an iWeld from LaserStar. The iWeld packs
more punch than most “Full Sized” machines in their class and cost
thousands less. This is rated in kW’s (kilowatts) or peak energy of
the machine. The higher the peak energy the more force the laser has.
The more force, the deeper penetrating the weld can be with less
power. Always check the specification on the manufacturers brochures.
Of course, higher joule machines come with higher wattage power
supplies. The higher wattage will give you more pulse frequency, but
not necessarily more penetrating power. This again goes back to the
peak energy. For Example, the iWeld 80J offers a 50W power supply
with 10 kW of peak energy. Others 80J machines offers 50W but only
has 6.0kW of peak energy. Joules and Peak Energy are the two main
factors when deciding on the machines performance, it like horsepower
and torque in your car.
For features, yes pulse shaping is imperative especially for new
users learning their machines. All LaserStar machines offer a
jewelers preset pulse shape embedded into the software and
programming. Our competitors lasers often arrive with no preset
jewelers programs or preset pulse shapes embedded into its memory.
Guess what, most never learn how to use the technology. Why do they
not preset the programming, well it is because they were not sure
what industry the laser was going to be installed in when it was
built in Europe.
Compressed air can be a nuisance with the loud compressor, but all
LaserStar can be ordered with it also. In 4 years, I have not sold
one compressed air option and most customers enjoy the additional
argon port instead to pinpoint a cover gas when the main diffused
cannot reach the point of weld.
Sweet Spot is more of a marketing term and we offer the similar
solution, Soft Touch. Again, in 4 years, I only sell the Soft Touch
option for special industries such as aerospace, tool and die and
medical devices. We you build machines to order, you can custom
tailor the machine and beam profiles to the customers exact needs
instead of making one machine for all. Jewelry metals are highly
reflective and the higher peak energy the better the laser beam
couples the material instead of reflecting off the piece.
LaserStar is proudly built in the USA and is the only laser built to
order based. Machine durability is relative to how one maintains
their machine. There are basic requirements and yes, machines will
last a very long time when properly maintained.
Do not forget the most important aspect of buying a laser, the
training provided by knowledgeable and highly skilled experts.
LaserStar offers a 2 day formal training course where you will learn
so much more then how to turn on your new laser. These are just a few
of my thoughts!
