The unique “Mixed Pulse” process developed by Megmeet engineers represents a breakthrough in MIG/MAG welding efficiency and quality. The technology intelligently combines the characteristics of a stable pulsed arc with the dynamics of a controlled short circuit. As a result, the welding arc is lower, more concentrated and exhibits much better resistance to external disturbances. In practice, this means the welder can work at speeds more than 20% higher than standard pulsed methods, while maintaining full control over the process.

The key advantage of “Mixed Pulse” is the increased concentration of arc energy, which leads to deeper and more uniform fusion, especially when welding thick materials or making fillet welds and butt joints with full fusion. Less heat input minimizes the risk of deformation of the welded part and preserves its mechanical properties. The process also generates a minimum amount of spatter, which translates into an aesthetically pleasing weld and reduces the time required for final processing. The life of chuck consumable parts, such as current tips, is also extended thanks to optimized material transfer.

“Flexible Short-circuit Transition” technology is Megmeet’s advanced solution that redefines short-circuit arc welding, making it cleaner and more controlled. The system is based on precise detection of the moment of constriction of the liquid metal droplet at the end of the welding wire and ultra-fast chopper control current technology. At the critical moment of the droplet’s passage into the welding pool, the current is rapidly reduced to the arc support level, allowing the droplet to merge calmly and smoothly into the pool.

The main benefit for the professional is the significant reduction in spatter – up to more than 70% compared to conventional DC short-circuit welding. The spatters that do form are fine and do not permanently adhere to the surface of the material, eliminating or significantly reducing the need for time-consuming grinding and cleaning. In addition, the entire droplet formation and transfer cycle is optimized to minimize heat input, which is crucial when welding thin sheet metal, overheat-sensitive materials and when making boundary layers. The system also provides excellent gap bridging capability, which is invaluable when working with parts with an inaccurate fit.

The MEGMEET Artsen III 400Q is designed to operate in the toughest industrial environments where reliability and production continuity are a priority. The unit offers an impressive rated welding current of 400 Amps at 100% duty cycle at an ambient temperature of 40°C. This means that the welder can run continuously at full power without the risk of overheating or performance degradation, which is crucial in automated production lines and for large construction projects.

To ensure such high performance and thermal stability, the Artsen III 400Q in “Water-cooled Package” configuration (cat. no. R06020310) is equipped with an integrated, high-performance liquid cooling system. This system efficiently dissipates heat from key components of the power source and, just as importantly, from the welding torch (when using a suitable liquid-cooled chuck). As a result, the operator can work comfortably even at high parameters, and the service life of both the welder and accessories is significantly extended. This solution translates directly into increased productivity and reduced operating costs.

The Megmeet Artsen III 400Q focuses on intelligent management of the welding process, offering the user advanced tools to optimize work. The device allows as many as 99 individual welding programs (JOB) to be stored in memory. Each program can contain precisely defined parameters for a specific task, material, thickness or welding position. This function is invaluable in batch production, where repeatability and the highest quality of each weld are crucial. The operator can instantly switch between saved settings, eliminating the risk of errors and reducing preparation time.

Another element testifying to the modernity of the Artsen III 400Q is the integrated U-Disk port. It allows not only easy backup of saved JOB programs, but most importantly the seamless updating of the welder’s system software. This allows users to easily implement the latest enhancements, new synergy curves or personalized features developed by Megmeet’s R&D centers. This ensures that the machine will always operate at top efficiency and be ready for future technological challenges in welding.
