LightWELD Frequently Asked Questions (FAQ)

Is LightWELD really faster than MIG and TIG welding?

Yes, LightWELD travel speed is up to four times faster than traditional methods, fixturing is simpler or not necessary, and post-weld grinding or sanding is not needed or significantly reduced – all of which increases productivity while minimizing rework.

Is LightWELD really that easy to learn?

Yes, compared with MIG and TIG welding, either of which can take a lifetime to master, LightWELD is quick to learn, allowing new users to make high-quality welds in just a few hours.

The controls look confusing. How do I know what to adjust?

LightWELD comes preloaded with optimized welding parameters for the most common materials and thicknesses. You can adjust the power up or down to match your travel speed and desired penetration, and you can save those settings and recall them as needed.

Can LightWELD weld dissimilar metals or parts with different thicknesses?

Yes, you can easily weld dissimilar metals like copper to stainless steel or to aluminum, plus parts with different thicknesses across all weld joint types: tee, butt, corner, lap and edge.

What is the maximum material thickness that can be welded?

For stainless steel, galvanized steel, mild steel and aluminum, you can weld single-sided up to 4 mm and double-sided up to 10 mm – copper single-sided up to 1 mm and double-sided up to 2 mm.

What about vertical welding or upside down welding?

LightWELD excels at both vertical and upside down welding since there are normally no consumables and minimal spatter produced, making it safe and easy to weld in any position.

Is the laser beam constant or can it be pulsed?

LightWELD offers five modes of operation to match your needs:

• Continuous wave - the laser is on constantly for maximum penetration and travel speed
• Pulsed mode – laser pulses producing less energy for slower welding with less heat input
• Tack mode – to create identical tack welds
• Stitch mode – used for repeated tacking or overlap welds
• High peak power mode – short bursts of high power used to penetrate reflective metals

What is the duty cycle?

You can run LightWELD at 100% duty cycle at the maximum 1500 watts of laser power.

What’s wobble welding?

Wobble welding oscillates the beam back-and-forth at various frequencies to produces wider seams and more aesthetic welds. It is also helpful for parts with poor fit-up.  LightWELD comes with optimized, preprogrammed wobble parameters and allows on-the-fly control of up to 5 mm of wobble welding at adjustable frequencies up to 300 Hz.

Where is LightWELD manufactured?

The heart of the system is the laser source, proudly Made in the USA at our production facility in Oxford MA, USA.  Final system assembly, testing and calibration is performed at our Marlborough MA, USA facility using additional components sourced through approved suppliers where we seek ISO 9000-2015 certification and who provide effective support, adhere to the highest ethical standards and have a proven record of law-abiding conduct.
