Remove Rust, Paint and Oxide Without Marking, Warping or Discoloring the Part Underneath
The DenaliWeld Jet MOPA uses a 300W pulsed MOPA fiber laser scanning at up to 60,000 mm/s across a 350 mm cleaning width, plugs into 220V single-phase power, and draws just 1.3 kW.
Some cleaning jobs are less about speed than about what is left behind. Injection molds, polished stainless, thin aluminum panels, restoration parts, electrical contacts and wood or stone surfaces can all be ruined by abrasive blasting, chemical strippers, or a laser that puts too much heat into the part. The answer is a pulsed laser: instead of a continuous beam, it fires extremely short, high-peak pulses that ablate the contaminant before heat has time to spread into the substrate.
The Jet MOPA is DenaliWeld's pulsed cleaner. Its MOPA (Master Oscillator Power Amplifier) source lets pulse characteristics be tuned to the coating, so it can lift rust, paint and oxide while leaving the base material intact. It is air-cooled, runs on ordinary single-phase power, is assembled in Elgin, Illinois, and carries a 3-year parts and labor warranty.
Clean Delicate and Finished Surfaces Without Heat Damage
A continuous-wave cleaner delivers steady energy, which is fast on heavy rust but heats the part, and that heat can warp thin sheet, blue stainless or etch a polished face. A pulsed MOPA laser concentrates its energy into brief pulses with high peak power, so the contaminant vaporizes while the surrounding metal stays cool. DenaliWeld describes the result as cleaning with minimal to no trace on the base material. For a mold shop, that means removing residue without changing cavity dimensions; for a restorer, it means stripping paint from an original panel without thinning the metal.
Clean Wood, Ceramics and Plastics as Well as Metal
Because pulse energy can be dialed down and controlled, MOPA cleaning is not limited to metals. DenaliWeld rates the Jet MOPA for removing contaminants from metal, wood, ceramics and plastics, which a high-power continuous cleaner would scorch. That opens up work like cleaning stone and ceramic surfaces, stripping coatings from composite or wooden parts, and preparing mixed-material assemblies. The air-cooled cleaning head weighs about 980 g (2.16 lb) and is rated by DenaliWeld for up to four hours of stable operation without overheating.
Cover a Wide Path Quickly With 60,000 mm/s Scanning
The Jet MOPA's scanning head moves the beam at up to 60,000 mm/s and sweeps a cleaning path up to 350 mm (13.78 in) wide, three times faster scanning and over four times the width of DenaliWeld's 2000W continuous cleaner. A wide, fast scan spreads energy evenly across the surface, which gives a uniform finish without the stripes that come from a narrow beam moved by hand. Its 210 mm focal length keeps the working distance comfortable for detailed work on molds, parts and panels.
Plug Into Standard Power and Roll It Where You Need It
At 1.3 kW and 6A on 220V single-phase, the Jet MOPA draws a fraction of the power a high-wattage continuous cleaner needs, so it can run from a typical shop circuit without a new electrical service. The air-cooled design removes the chiller, and the included cart and 5 m (16.4 ft) fiber cable make it easy to move between workstations or onto a job site. DenaliWeld rates the machine for reliable operation from -10°C to 40°C (14°F to 104°F).
Start Cleaning in One Click, Then Fine-Tune by Surface
The monitor and PLC control system loads preset parameters so a new operator can start with a proven setting, while the capacitive touchscreen gives access to power, frequency, cleaning width and process number for specific coatings. Real-time status and alarm notifications keep the operator informed. That combination lets one machine handle very different jobs, from light oxide on stainless to paint on aluminum, by switching programs instead of changing equipment.
Skip the Media, Solvents and Cleanup
The Jet MOPA uses electricity, gas at 15–20 L/min to protect the optics, and occasional protective lenses. There is no blast media, no chemical stripper, and no secondary cleanup of grit or residue. For mold maintenance, restoration and precision cleaning, eliminating that waste and the masking work it requires is often worth as much as the cleaning speed itself.

Choose the Jet 2000 if your main job is stripping heavy rust, mill scale and thick coatings from steel structures, equipment or frames, and speed per square foot matters most.
Choose the Jet MOPA if you clean molds, thin sheet, aluminum, stainless or non-metal surfaces where heat input, discoloration or base-material damage would be a problem.
Frequently Asked Questions about the DenaliWeld Jet MOPA 300W Laser Cleaning Machine
Q: What does MOPA mean on a laser cleaner?
A: MOPA stands for Master Oscillator Power Amplifier. It is a fiber laser design that allows pulse characteristics to be adjusted, so the cleaner can be tuned to remove a specific coating while limiting heat in the base material.
Q: What's the difference between the Jet MOPA and the Jet 2000 laser cleaner?
A: The Jet MOPA is a 300W pulsed cleaner for precise, low-heat work on delicate surfaces and non-metals. The Jet 2000 is a 2,000W continuous cleaner built for fast removal of heavy rust and thick coatings on steel. The MOPA scans faster and wider; the 2000W removes more material per hour on heavy jobs.
Q: Can a 300W pulsed laser remove heavy rust?
A: Yes, but more slowly than a high-power continuous cleaner. The MOPA's strength is a clean, damage-free finish. If heavy rust on large steel structures is your main job, the 2000W continuous Jet 2000 is the faster tool.
Q: What materials can the Jet MOPA clean?
A: DenaliWeld rates it for removing contaminants from metal, wood, ceramics and plastics, including rust, paint, oxide layers and surface residue.
Q: What power does the Jet MOPA need?
A: It runs on AC 220V single-phase power, draws about 6A and consumes roughly 1.3 kW.
Q: Does the Jet MOPA need a chiller?
A: No. It is air-cooled, and DenaliWeld rates the cleaning head for up to four hours of stable operation without overheating.
Q: Is laser cleaning safe?
A: It is a Class 4 laser. Use laser-rated eye protection (a laser-safe helmet is included), control the work zone with barriers or laser curtains, and run fume extraction, since removed coatings become airborne particulate.
Q: Is the warranty valid when I buy through The Maker's Chest?
A: Yes. As an authorized DenaliWeld distributor, The Maker's Chest sells the Jet MOPA with the full 3-year parts and labor warranty. Repairs are handled at DenaliWeld's U.S. facility; shipping to and from it is the owner's responsibility.
Q: What is the return policy on the Jet MOPA?
A: Purchases from The Maker's Chest include our 75-day return window. If the Jet MOPA is not the right fit for your shop, contact us within 75 days of delivery to arrange a return.
Q: Why buy the Jet MOPA from The Maker's Chest instead of directly from DenaliWeld?
A: The price is the same and the 3-year DenaliWeld warranty applies in full, because The Maker's Chest is an authorized distributor. You also get a 75-day return window and a U.S. team that helps you choose between continuous and pulsed cleaning for your actual parts before you buy, and that supports setup, consumables and warranty questions afterward.
