Strongest industrial handheld laser welding machine

Based on the self-developed “small core diameter” laser technology,the STR-HW Series handheld laser welders adopt a new dual circuit refrigerant direct cooling system an dintegrated structural design. These welders can provide customers with such experiences as high effectiveness, large penetration, high energy-efficiency, and high convenience. These welders can weld various metal materials, including aluminum, stainless steel, carbon steel, galvanized sheet, brass, etc.(The welder for welding special materials can be customized per user’s requirements).

STR-HW Series Technical Parameter

STR-HW200	STR-HW350	STR-HW450	STR-HW550

Integrated Design of the Complete Set Ensures Higher Welding Efficiency Longer Service Life, and Lower Maintenance Costs

The whole set of the welders features integrated design, proprietary welding guns and welding wire feeder, built-in welding process packages, linked operation and smoother coordination among different components.
Meanwhile, it is the first product of its kind to incorporate the adaptive welding process package repair function, bringing higher working efficiency and better welding experience.

Higher Stability Ensures Round-the-clock Operation

Capable of 24 × 7 continuous welding, thanks to the refrigerant direct cooling system that is developed independently by STR and welding gun insulation material that can ensure long-term use without becoming hot or shutdown.

Adopting Dual Circuit Refrigerant Direct Cooling Technology to Eliminate the Shortcomings of Traditional Air-cooled and Water-cooled Welder

The operating environment temperature of conventional water-cooled handheld welders is between 5℃ and 50℃, while that of air-cooled handheld welders is between -10℃ and 35℃. The refrigerant direct cooling system developed independently by STR ensures the handheld welder good environmental temperature adaptability with an operating temperature ranging from -20℃ to 60℃.

“Small-core diameter” Laser Technology

Small core fibers have better beam quality and higher energy density under the same power.

Dual-Circuit Refrigerant Direct Cooling Techonology Different from the air cooling system, STR-HW series handheld welding laser uses refrigeration cooling system. The operating temperature range is: -20°C~+60°C with better ambient temperature adaptability, and 7×24 continuously work.
Inegrated Cable Technology Integrating multiple connecting wires between various components in a traditional welding torch into armored cable with diameter of only 17mm. Greatly improve the welding results and operation flexibility. Makes easlier angle rotation and less fatigue with long term operation.
Modular Design of Welding Torch The simplified design welding torch, adopt beam collimation module input , and the fully enclosed design minimize the refraction and scattering of laser energy transmitted between the lenses. Industrial plastic + soft rubber design of the gun handle greatly reduces the torch weight and have better thermal insulation performance.

STR-HW WELDERS ADVANTAGES

An Innovation to Traditional Arc Welding Technology Effectively Improves Welding Efficiency

TIG Welding TIG welding is a time-consuming, two-handed welding method that requires experienced and skilled operators.TIG welding generates extremely high heat, resulting in distortion of thin materials, poor cosmetic results, difficulty in welding copper, and limitations in welding metals of varying thicknesses.	STRONGEST LASER Compared with MIG or TIG, STRONGEST LASER is based on the company’s independently developed “small core diameter” laser technology, adopts a new dualcircuit refrigerant direct cooling system and an integrated structure design, providing customers with higher efficiency, higher melting depth, higher energy saving and more convenient experience.	MIG Welding MIG welding requires consumable wire, material pre-cleaning, and beveled joints in thick metals to allow for complete penetration. Movement and working angles are limited, and vertical positions are challenging.
