Core Components
①JCT laser welders integrate four core pillars
- Our proprietary fiber laser source,
- Advanced dual-circuit refrigerant cooling compressor,
- A high-precision digital control motherboard,
- The lightweight STR-K20 ergonomic welding torch
Unlike traditional water chillers that require bulky external tanks and risk freezing or scaling, our closed-loop refrigerant system circulates high-efficiency cooling gas directly through thermal exchange blocks.
This maintains optimal optical temperatures instantly, eliminating condensation risks and enabling continuous 72-hour operation in high-humidity or 60°C desert climates.
②How Refrigerant Cooling Works
Core Advantages
All-In-One Refrigerant System
Integrated machine design featuring a dual-circuit intelligent refrigerant thermostat. Delivers stable 7×24 hour continuous operation even in extreme -30°C to 60°C workshop climates
Small-Core Technology
Advanced beam shaping delivers higher energy density. You get deeper weld penetration at lower electrical input.
STR-K20 Lightweight Torch
Weighing only 617g with an ergonomic grip. Features 360-degree anti-torsion armored cabling and an innovative protective window wind-escape design to extend lens life by 30%.
Smart Self-Check System
Real-time monitoring of lens temperature and gas pressure. Automatically detects anomalies to protect optics and prevent operational downtime.
Zero-Coding Setup
30+ preset material process libraries. Operators adjust parameters via rotary knob and touch screen instantly—plug and play
Find Your Ideal Model by Material & Thickness.
1mm – 3mm (Light-Duty)
Choose LITE S Series. Delivers smooth, oxidation-free beads with zero post-grinding at single-phase 220V.
3mm – 6mm (Medium-Duty)
Choose HW Series. Deep penetration and stable 1500W-2000W output for seamless workshop fabrication.
6mm – 10mm (Heavy-Duty)
Choose Master X Series. Three-phase 380V power and high energy density handle thick plates effortlessly.
1mm – 3mm
Choose LITE S or HW Series. Our dual-circuit refrigerant cooling and small-core beam overcome high reflectivity barriers, preventing porosity and cracking
3mm – 7mm
Choose LITE S or HW Series. Our dual-circuit refrigerant cooling and small-core beam overcome high reflectivity barriers, preventing porosity and cracking
1mm— 4mm
Choose LITE S or HW Series. Zinc vaporization often causes spatter in standard machines. Our adjustable pulse modes and stable wire feeding suppress spatter completely, protecting the surface coating integrity.
1mm – 3mm
Choose HW or Master X Series. Highly conductive and reflective copper demands high energy concentration. JCT small-core beams stabilize the melt pool instantly, achieving reliable electrical contact joints without burning through.

FAQ
Q1: How does refrigerant cooling differ from traditional water chillers?
Refrigerant cooling uses a closed-loop gas compressor cycle, eliminating external water tanks, pumps, freezing risks, and scale buildup. It maintains stable temperatures in 60°C environments
Q2: What are the main advantages of refrigerant-cooled handheld laser welders compared to traditional water-cooled machines?
Zero Maintenance & No Water Needed:
Powered by a dual-circuit built-in refrigerant refrigeration system, it eliminates the need for external water tanks, hoses, and anti-freezing liquids, resulting in ultra-low maintenance costs.
Instant Start-Up: Ready to weld immediately upon startup. There is zero waiting time for water temperature stabilization.
Highly Mobile & Lightweight: Compact and integrated design makes it exceptionally flexible for on-site, mobile welding operations across diverse workshop environments.
Q3: Can this machine handle both welding and rust cleaning?
Yes. Master X and HW series support multi-functional integration, allowing quick switching between welding, cutting, and rust/paint removal modes via software presets.
Q4: Do operators need professional programming skills?
No. The system features 30+ pre-programmed industrial process packages. Operators can select materials and thickness on the touch screen for immediate -play operation.
Q5: Does JCT support custom voltage configurations for overseas markets?
A: Yes. As a direct source manufacturer, we customize input voltages (e.g., 220V, 380V, 415V, 440V) to meet your local industrial standards in your country.
Q6: What is included in the standard export package?
Each machine ships with the main welding unit, STR-K20 integrated torch with 5m/10m armored cable, wire feeder, safety goggles, spare nozzles, and protective lenses inside a heavy-duty export wooden crate.
Q7: How does JCT handle after-sales technical support?
We provide 24/7 online video troubleshooting, remote diagnostic software updates through the built-in app, and fast international dispatch shipping for replacement parts.
Q8: Why should I buy directly from JCT instead of a local distributor?
Buying directly from JCT removes distributor markups, ensures direct engineering collaboration for custom requirements, and guarantees 100% genuine factory-tested components.
