Independent laser technical services for the machines that cut, weld, mark, engrave, clean and clad in production. Field service and breakdown support, scheduled maintenance, installation and commissioning, and component-level repair: the laser source, the cutting head, the controls and drives, the delivery cables, the gas and extraction path, and the safety circuits around them. On site nationwide across the United States and Canada, from Parsippany, New Jersey.
An industrial laser installation is four or five separate systems wearing one machine name. There is the frame and its motion, the laser source, the head or process optics, the controls and drives, and the services around them: chilling, assist gas, extraction, and the safety circuit that lets the whole thing run. A machine can stop because any one of those failed, and the machine name tells you nothing about which.
That is the practical reason an owner gets bounced between suppliers. The machine builder points at the source. The source vendor points at the machine. The integrator has moved on. We work across all of it, so a single request can cover the whole installation instead of being split into separate guessed failures.
In practice owners come to us for four things. Breakdown service when a machine has stopped and production is waiting. Industrial laser technical support when a machine still runs but no longer produces sellable parts. Scheduled maintenance, set out on the preventive maintenance page as monthly and quarterly programs. And installation, commissioning and relocation when equipment is arriving, moving or being brought back into service. Whichever it is, you are talking to a laser equipment service technician rather than a call centre.
No output, falling power, protection trips, burned delivery connectors. Fiber and CO2 sources, power supplies, and the cables between the source and the head.
Cut quality gone off, focus drifting, protective windows burning through, height sensing lost. Collimator, focus module, nozzle and sensing hardware.
Machine down, axis and servo faults, positioning lost, gas and extraction problems, control PCs that no longer boot.
Sound mechanics, dead electronics. Control and drive replacement, source replacement, and machines whose builder no longer exists.
Sheet and plate cutting is the largest installed base we are called to, and it covers more machine types than the phrase suggests: flat-bed fiber cutters, tube and profile cutters, combination flat-and-tube machines, coil-fed and blanking lines, plate gantries, and the robotic cells built around the same optics. Imported machines from Bodor, HSG, Senfeng, Han’s, GWeike, Penta, Accurl, DNE, Golden Laser and others are a large part of that base, and so are Trumpf, Amada, Bystronic, Mazak Optonics, Prima Power, Mitsubishi, LVD and Salvagnini machines that have outlived their support contracts.
What owners report is usually a cut, not a component: more passes than the job used to need, dross on the underside, an edge that is no longer square, piercing that fails on thicker plate, or a machine that simply stops mid-program. Those descriptions are the right starting point. Which of the five systems is behind them is what an evaluation establishes.
Fiber laser cutting machine repair, CO2 laser cutting machine repair and tube laser cutting machine repair are all within scope, on the machine and on the parts that feed it. Detail on each: cutting machine repair, cutting head repair and laser source repair.
Laser welding installations arrive in three shapes: handheld welding guns fed by a fiber source, fixed optics on a fixture or turntable, and robot-mounted heads with wobble or seam-tracking optics. Brazing cells share most of the same hardware with a wire feed added. Whatever the shape, the service question divides the same way: the source and its delivery fiber, the process optics and their protective glass, the motion or robot path, and the gas, fume extraction and interlocks around the process.
What gets reported is weld quality that has drifted, spatter or porosity that was not there before, a wire feed that surges or stops, protective glass life that has collapsed, a wobble or seam-tracking head that no longer behaves, a robotic welding cell that faults mid-cycle, or a welder that will not fire at all. Those are in scope, together with the source behind them and the electrical and control hardware that drives them.
The work covers laser welding machine repair on fixed and robotic installations, handheld laser welder repair, including IPG LightWELD service and the other handheld guns sold as portable welding systems, and brazing cells with their wire feed. Welding optics and cutting optics are different products with overlapping failure modes; if the source is the suspect, the laser source page covers it.
Marking and engraving equipment spans fiber marking sources on galvo scan heads, UV and green marking systems, CO2 markers on non-metals, and deep-engraving machines built around the same architecture. On a production line the marker is rarely alone: it sits with a controller, a trigger or encoder input, an enclosure and extraction, and often a vision reader that accepts or rejects the mark. Part marking, serialisation, 2D codes, nameplates, tooling identification and deep engraving all run on this hardware.
What owners describe is a mark: a marker that is no longer marking at all, weak or shallow output, uneven depth across the field, a mark that is broken or inconsistent between parts, position drifting, or a mark that fails the reader while looking fine to the eye. Galvo scan head faults, f-theta optics, the marking controller and its interfaces, and fiber, UV, green and CO2 engraver sources are all inside that scope. That last distinction matters, because a marking complaint and an inspection complaint send the work in different directions. Our scope covers the marking source, the scan head and f-theta optics, the RF or driver electronics, the controller and interfaces, and the extraction around it.
Fiber laser marker repair, CO2 laser engraver repair, UV and green marking system service, and galvo scan head service all sit here, together with the marking controller and the extraction around the enclosure. Coding and marking on packaging lines is covered in more depth on the packaging coding and marking page, and the same source and scan-head work applies.
Laser cleaning cells are now common for rust and scale removal, paint and coating stripping, weld and mould cleaning, pre-weld preparation and tooling maintenance. Most are a pulsed or continuous fiber source, a scanning head, an extraction and filtration unit that matters far more than people expect, and a fixture or robot. Handheld cleaning guns are the same hardware in a portable package.
Laser cleaning machine repair and maintenance covers rust removal machines, pulsed laser cleaner service and CW laser cleaner service, handheld cleaning guns, and the scanner and filtration hardware that decide whether the cell keeps working. The reports are usually about effect rather than hardware: cleaning rate dropped, weak output, no output at all, the process leaves a shadow or a pattern, the scanner no longer sweeps evenly, the head or window fouls quickly, or the extraction no longer keeps the cell clear and the operator can smell it. The source, the scan head and protective optics, the drive electronics, and the extraction and filtration path are all in our scope, and on cleaning systems the extraction is a service item in its own right rather than an accessory.
Cladding and laser metal deposition installations add a powder or wire feed, a coaxial or lateral cladding head, shielding gas and often a rotary or robot axis to the same source and control hardware. They are used for wear and corrosion overlay, restoring worn shafts, rolls and dies, and adding material where a part would otherwise be scrapped.
Laser cladding system repair covers the cladding head and its optics and cooling, the powder or wire delivery hardware, and the source and motion behind them. What gets reported is a deposit: inconsistent bead, poor fusion, powder feed that surges or blocks, a head that overheats, or shielding that no longer protects the pool. Our scope covers the source, the cladding head and its optics and cooling, the powder or wire delivery hardware, the motion and control path, and the gas and extraction around the cell.
Fiber took most of the new metal-cutting market, and that has produced a common but wrong assumption that CO2 machines are finished. They are not. CO2 remains the right tool for a long list of non-metals and for applications where beam quality and wavelength suit the material: acrylic and plastics, wood and composites, textiles, paper and board, glass marking, film perforation and a great deal of converting work. A large installed base of sealed and slab CO2 machines is running today in job shops, sign shops, converting plants and packaging lines.
Our CO2 scope is real and current, not legacy tolerance. It covers CO2 cutting machines, CO2 engraving machines and CO2 marking systems; sealed and slab sources including Coherent, Rofin-Sinar legacy, Synrad, Luxinar, Iradion and the Reci and Yongli tubes common on imported machines; the RF supply and drive electronics; CO2 laser power supplies; mirrors, lenses and beam delivery; the chiller and its loop; and the extraction and filtration path. A CO2 laser that is not firing, that has lost power, or that fires but no longer marks or cuts to the same depth are three distinct reports, and each has candidates in the RF supply and drive electronics, the beam path and the thermal loop as well as in the tube or slab itself. Which one applies is a finding. Where a CO2 source has genuinely reached end of life on a machine with sound mechanics, replacement or conversion is a retrofit question rather than a reason to scrap the machine, and we will say plainly which of the two your machine is.
CO2 sources inside packaging and converting machinery are covered alongside those machines on the laser die cutting and converting page.
Laser machine installation, laser commissioning service and laser machine relocation are the same skill set pointed in two directions. A machine arriving for the first time needs placement coordination, utilities confirmed against what it actually draws, mechanical and optical setup, first cuts or first process trials against an agreed acceptance method, and operator handover. Imported machines arrive with documentation of varying quality and that is normally where the surprises are.
A machine being moved needs the same work in reverse and then forward again: condition documented before anything is disconnected, photographs and cable maps taken, the dismantling scope agreed, utilities checked at the new site, rigging coordinated with partners, then reassembly, setup and a documented start-up. Plant moves, line reconfigurations and equipment bought at auction all fall here.
We also carry out field execution as a subcontractor for machine builders, dealers and integrators who need hands in the United States or Canada without opening their own branch. Scope, travel and responsibilities are set out in writing before anyone books a flight.
The reason a machine is worth keeping is usually that the expensive parts are fine. Component-level work is what makes that true in practice: boards repaired rather than only exchanged, obsolete parts substituted with a current equivalent matched on the parameters that matter, and a subsystem engineered out and replaced where repair is not the right answer. Delivery cables and connectors, power supplies and drivers, control and interface boards, scan heads and optics, and thermal control hardware all sit in that scope.
Where a part no longer exists, the honest options are substitution, engineered replacement, or telling you the machine is not worth the money. We will say which one applies and what it costs before you commit.
Stated as scope rather than as a method. What a given machine needs is settled by its condition and by the written findings, and nothing is repaired, substituted or modified until you approve the scope and the price.
| Subsystem | Typically repaired | Typically replaced |
|---|---|---|
| Laser source | Power supplies, driver electronics, control and interface boards, thermal control hardware, and the delivery cable and connector assembly | Pump modules and source assemblies that are beyond economic repair, on a quoted and approved basis |
| Process optics | Collimators, focus modules, nozzles, protective window assemblies, mirrors and beam delivery hardware, sensing and height-tracking hardware | Consumable optics and windows, and head assemblies where the quoted repair is not the better value |
| Controls and motion | CNC and control hardware, HMI and industrial PCs, servo drives and motor groups, encoders, I/O and safety circuits | Obsolete controls and drives, replaced as a matched chain rather than one part at a time |
| Services around the machine | Chillers and thermal loops, assist gas path and regulation, extraction and filtration, compressed air and cabinet cooling | Units at end of life, with the replacement sized against what the machine actually needs |
| Documentation | Pinouts, measured operating values, control sequences and as-found configuration recorded during the engagement | Delivered with the machine; where original acceptance data does not exist we say so rather than substituting an assumption |
We do not promise a specific repair before diagnosis, and we do not certify equipment to original published specifications where the original acceptance data and the corresponding standards are unavailable.

Brand and model names identify equipment only and remain the property of their respective owners. Work on equipment under an active manufacturer warranty is performed only within a scope authorized in writing by the equipment seller or manufacturer.
Work is carried out to the site rules and the laser safety arrangements in force at your facility. Where a machine has to be run with guarding open for a measurement, that is agreed in advance with your safety officer and recorded in the scope.
Yes, and they are a large part of what we do. Bodor, HSG, Senfeng, Han’s, GWeike, Penta, Accurl, DNE, Golden Laser and similar machines are common in North American shops and often have thin local support. Send the machine model, the source model if you have it, and the control platform on the operator panel, and we will tell you what can be established.
Not as a rule. A dissolved builder removes the documentation and parts route, not the machine. Where controls or a source are genuinely unobtainable, replacing that subsystem is a retrofit question, and a machine with sound mechanics is frequently worth it. We tell you which of the two you have before you spend anything.
