Raycus

Raycus - Company Overview

Raycus is headquartered in Wuhan, Hubei, China, and is recognised as a key high-tech enterprise under China's National Torch Program. The company designs and manufactures fiber laser sources - the sealed module that generates the high-energy laser beam, which is then delivered through a fiber-optic cable (via a QBH connector) to a cutting head or welding head. Raycus also produces the supporting components - laser diodes, gain fiber, and control electronics - in-house, which is part of why Raycus units are widely available and cost-effective compared with premium Western brands.

What makes a Raycus source a Raycus source: a third-generation single-module CW design for the 1.5kW-3kW range with high electro-optical conversion efficiency, an optimised second-generation fiber transmission system for stable, sophisticated cutting in thick-sheet applications, and multi-module designs (4kW-12kW+) that combine multiple single-module units inside one housing for higher total output. Every Raycus source uses a closed-loop water-cooling system circulating deionised water through the diode and gain-fiber assembly - this is the single most important maintenance point for every Raycus owner.

Raycus Fiber Laser Source - The Full Range

Raycus laser sources split into two main lines, and knowing which one your machine needs is the single most important thing before ordering:

• RFL-C Cutting Sources - Single-module. The 1.5kW, 2kW, and 3kW units are the most common Raycus cutting sources in India, used on standard CNC laser cutting machines for mild steel, stainless steel, and aluminium sheet up to medium thickness.
• RFL-C Cutting Sources - Multi-module. The 4kW, 6kW, 8kW, and 12kW units combine multiple laser modules inside one housing for higher total power, used for thick-plate cutting (16mm+ mild steel) and high-volume production lines.
• RFL-C-CE Welding Sources. The 1.5kW, 2kW, and 3kW welding-specific sources are built for handheld and robotic fiber laser welding guns, optimised for continuous-duty welding rather than the pulsed piercing cycles used in cutting.
• QBH connector across the range. Both cutting and welding sources use the standard QBH fiber connector, so the head/gun side stays compatible regardless of which Raycus power tier you choose - only the source housing and chiller sizing change.

Quick rule: if your machine cuts sheet metal, you need an RFL-C cutting source matched to your existing power rating (printed on the source label). If your machine welds, you need an RFL-C-CE welding source. When in doubt, the model and power are printed on the source housing label - send us a photo.

Raycus Laser Source Models Explained

Raycus 1.5kW Cutting Source (RFL-C1500)

The entry-level single-module CW source in the Raycus cutting line, rated to 1.5kW. It is the most widely fitted source on entry and mid-range CNC laser cutting machines in India, suitable for mild steel up to roughly 10mm, stainless steel up to roughly 6mm, and aluminium up to roughly 4mm depending on assist gas and machine setup. It uses a third-generation single-module design for higher electro-optical conversion efficiency than older Raycus generations, with an optimised fiber transmission system for clean, narrow-kerf cuts. Pairs with a minimum 3kW chiller.

Raycus 2kW Cutting Source (RFL-C2000)

A step up from the 1.5kW single-module source, offering more cutting speed and slightly greater material thickness capability - mild steel up to roughly 14mm, stainless steel up to roughly 8mm. It is a common upgrade path for shops that started with a 1.5kW machine and need faster cycle times without moving to multi-module power. Same QBH connector and broadly similar footprint to the 1.5kW unit, simplifying machine retrofits. Recommended chiller: minimum 3kW-4kW.

Raycus 3kW Cutting Source (RFL-C3000 / RFL-C3000S)

The workhorse of the Raycus single-module cutting range and the source we sell the most replacement units for. Rated to 3kW, it handles mild steel up to roughly 18-20mm, stainless steel up to roughly 10mm, and aluminium up to roughly 8mm in typical configurations. The "S" revision (RFL-C3000S) is the current production version, with the same compact, water-cooled, single-module housing and QBH connector as earlier 3000-series units. If your shop runs a 1.5kW-3kW class CNC laser cutting machine, the 3kW source is the most common replacement and upgrade target. Recommended chiller: minimum 6kW.

Raycus Multi-Module Cutting Sources (4kW-12kW)

The 4kW, 6kW, 8kW, and 12kW Raycus sources use a multi-module architecture - several individual laser modules combined inside one housing to deliver higher total power than a single module can provide. These are the sources fitted to thick-plate and high-speed production cutting machines, handling mild steel well beyond 20mm at the higher power tiers. Multi-module sources are larger, draw more power, and require proportionally larger chillers (12kW chiller minimum for a 6kW source, scaling up for 8kW and 12kW). They retain the QBH connector, so head-side compatibility (Raytools, WSX, OSPRI, BOCI) does not change - only the source housing, power draw, and cooling requirements scale up.

Raycus RFL-C-CE Welding Sources (1.5kW-3kW)

Raycus's dedicated welding-line sources, CE-certified and optimised for the continuous-duty cycles used in fiber laser welding rather than the high-peak, pulsed-piercing cycles used in cutting. The 1.5kW unit suits thin-sheet welding (up to roughly 3mm stainless steel), the 2kW unit handles medium-thickness joints (up to roughly 5mm), and the 3kW unit is suited to continuous production welding on thicker mild steel and stainless steel components. These pair with standard fiber laser welding guns via the same QBH connector, and require a matched chiller - a 1.5kW-2kW welding source needs a minimum 3kW chiller, while the 3kW welding source needs a minimum 5kW-6kW chiller for stable continuous operation.

Raycus Source Comparisons (Head-to-Head)

The three comparisons buyers ask about most when choosing or replacing a Raycus laser source.

1.5kW vs 2kW Cutting Source

Verdict: if your machine is rated for 2kW and your current source has failed, replace like-for-like with 2kW - do not under-spec to 1.5kW, as cutting speed and thickness capability will drop noticeably.

3kW vs 6kW Cutting Source

Verdict: match the source to your machine's rated power and your typical material thickness. Stepping up from 3kW to 6kW is a significant investment in source, chiller, and electrical supply - confirm your machine's head and optics are also rated for 6kW before upgrading.

RFL-C Cutting Source vs RFL-C-CE Welding Source (Same Power)

Verdict: do not interchange a cutting source for a welding source even at the same power rating - the duty cycle and beam-quality tuning are application-specific. Always order based on your machine type, not just the power number.

Raycus Laser Source Cooling & Chiller Requirements

Every Raycus laser source - cutting or welding, single-module or multi-module - is water-cooled, with a closed-loop circuit running deionised water through the diode and gain-fiber assembly at a controlled temperature, typically in the 22°C-25°C band. Getting the chiller right is not optional - it is the single biggest factor in Raycus source lifespan.

• 1.5kW-2kW source: minimum 3kW chiller capacity.
• 3kW source: minimum 6kW chiller capacity.
• 6kW source: minimum 12kW chiller capacity.
• 8kW-12kW source: chiller capacity scales proportionally - confirm exact sizing for your specific multi-module model.
• Water quality: deionised water only, with periodic resistivity checks - tap water or hard water causes scale buildup inside the cold plate and is a common cause of overheating faults.

SparesZone recommends TEYU S&A CWFL series chillers - purpose-built for fiber laser applications with precise temperature control, deionised-water compatibility, and flow-rate protection alarms. Using an undersized chiller, or a standard HVAC/process chiller not designed for laser applications, is the most common cause of Raycus source overheating and permanent module damage.

Genuine Raycus vs Unverified / Refurbished Sources

An honest comparison, because this is the decision every buyer is actually making when shopping for a "Raycus laser source" online.

SparesZone's position: we stock CE-certified Raycus laser sources only, with the power rating, application (cutting or welding), and connector type clearly stated, and a GST invoice on every order. A core component like a laser source is not the place to gamble on an unverified listing - replacing a wrongly-specced source costs far more in downtime than the price difference.

How to Choose the Right Raycus Laser Source

If you are specifying a Raycus source (replacement, upgrade, or new machine build), work through these five questions:

1. Is your machine a cutting machine or a welding machine? This determines whether you need an RFL-C cutting source or an RFL-C-CE welding source - they are not interchangeable even at the same power rating.
2. What power rating is your existing source? The power is printed on the source housing label. Replace like-for-like unless you are deliberately upgrading - and if upgrading, confirm your cutting head, optics, and electrical supply are also rated for the new power.
3. Single-module or multi-module? 1.5kW-3kW sources are single-module; 4kW-12kW sources are multi-module with a larger housing and higher power draw. Confirm physical clearance in your machine cabinet before ordering a multi-module replacement.
4. Is your chiller correctly sized? A replacement source will fail again quickly if the chiller is undersized for the new power rating. Check chiller capacity against the minimums above before installing.
5. What is your connector type? Raycus sources use the QBH connector across the range, which is compatible with Raytools, WSX, OSPRI, and BOCI heads - but always confirm your existing cable and head connector matches before ordering.

Unsure on any of these? Send your machine make/model, current source label (photo if possible), and application (cutting or welding) to +91 92740 95891 and we will confirm the exact Raycus model and chiller pairing.

Raycus Laser Source Troubleshooting Guide

The most common Raycus source-related problems and what actually causes them:

Rule of thumb: power and overheating problems → start with the chiller and water quality (cheap, fast to check). Output and beam-stability problems → check the QBH connector first, then consider source-internal faults.

Compatible Cutting Heads & Welding Guns

Raycus laser sources use a QBH fiber connector and are designed to work with all mainstream fiber laser cutting heads - Raytools, WSX, OSPRI, BOCI and others - on CNC fiber laser cutting machines, and with standard fiber laser welding guns on welding machines. The head/gun choice is driven by source power and your machine's existing setup, not by source brand. If you run a Raytools BM111 or BM114S head (very common in India), a matching Raycus source is a direct fit via the standard QBH connection.

SparesZone also stocks the consumables for the cutting heads you run alongside a Raycus source - nozzles, protective windows, and ceramic rings for Raytools, WSX, OSPRI, and BOCI heads - so you can source the source and its consumables from one place. Browse laser cutting heads →
