What the 50W Fiber Has To Offer
More average power means faster deep marking, deeper single-pass penetration, and the ability to handle slightly thicker material on light cutting work. For surface marking jobs — logos, serial numbers, QR codes, stainless contrast marks — the speed advantage over 30W is minimal, because those jobs are galvo-speed limited rather than power-limited. Where you feel the difference is on any job that involves significant metal removal.
What 50W still won't do well:
- Production sheet metal cutting. 50W handles very thin foil cutting on softer metals. For meaningful cutting work, 100W is the practical floor.
- Glass, wood, leather, acrylic, or fabric. Fiber wavelength limitations apply at any wattage.
- Powder-coated tumblers. CO2 galvo is the correct tool.

Critical note: Neither source at 50W offers color marking on stainless steel or titanium. Both use fixed pulse widths that cannot produce the controlled oxide layer MOPA color requires. If color marking is part of your work, you need a MOPA source — available at 30W (JPT M7 E) or 60W (JPT M7 E2/E/M-version). The 50W is for shops whose work is high-volume monochrome marking and depth engraving, where color is genuinely not required.
What's Included — Complete Working System
Every 50W configuration ships complete:
- Fiber source at your selected variant (Raycus 50QB or JPT LP)
- Sino-Galvo high-speed scanning head with dual red-dot positioning
- Two F-theta lenses of your choice — 70×70, 110×110, 150×150, 175×175, 210×210, or 300×300 mm
- Rotary attachment — D60 (rings/bracelets), D80 (cups/tumblers up to 70mm), or D100 (larger tumblers up to 90mm)
- Foot pedal for hands-free triggering
- OD5+ laser safety glasses
- EZCad 2 original software on USB
- Fixed aluminum worktable
Free DDP shipping to the US, Canada, and EU. Approximately 30 days delivery.
3-Year Warranty — And Why That Number Actually Matters
Both 50W variants carry 3 years of full coverage on the source and the complete machine — significantly longer than the 1-year warranties common on competing fiber lasers at this price point. Component failures within the warranty window ship a replacement to you at no cost; the broken part stays with you. Source defects go through the manufacturer's warranty with all freight covered. Lifetime email support continues afterward.
For a shop running a 50W as a daily production marker, that 3-year coverage is the difference between a repair bill in year two and a replacement part. Most competing brands make year two your problem.
The Maker's Chest Difference
75-day returns — Time to confirm the source variant you chose handles your applications, and that 50W is the right power level for your production volume.
USA-based technical support by phone and email — Setup, parameter library development, material optimization, troubleshooting.

Frequently Asked Questions
Q: Why would I choose 50W over 60W if the 60W has MOPA color marking?
If color marking is genuinely not part of your work — and won't be — the 50W at a lower price point gives you more average power than a 30W with the same fixed-pulse simplicity. The 50W LP in particular gives you JPT source quality and the 1–600 kHz frequency range for smooth surface finishes. If there's any realistic chance you'll want color marking in the next few years, the 60W MOPA is the smarter investment even at higher cost.
Q: What's the Raycus 50QB vs JPT LP difference in everyday production use?
For straight monochrome metal marking, the results are very similar. The JPT LP's 1–600 kHz frequency range vs. the Raycus's 30–60 kHz gives you meaningfully more control over surface finish and better results on plastics and some coated materials. If you mark a variety of materials or care about finish quality on faster jobs, the JPT LP is worth the premium. If your work is consistent metal marking on a small set of materials, the Raycus 50QB does it at a lower price.
Q: Can either 50W source mark anodized aluminum cleanly?
Yes to standard anodized marking. Both sources remove the anodized layer to reveal bright aluminum underneath, producing high-contrast marks. For true deep black annealing on anodized aluminum — the kind that produces a rich, inky black rather than a lighter contrast mark — a full MOPA source with adjustable pulse width is more effective. If that quality level is important to your work, look at the 60W MOPA listing.
Q: How do I set the Z-axis focal height? Is motorized Z available?
Both 50W configurations ship with manual Z-axis adjustment. A motorized Z-axis upgrade is available for shops that frequently change material thickness or need repeatable focus across varied production setups. Best to add at purchase.
Q: Is LightBurn compatible?
Yes. Both 50W source variants use the BJJCZ controller, which is fully compatible with LightBurn galvo mode on Windows, macOS, and Linux. EZCad 2 is included for Windows users. Mac users will use LightBurn.
