Megmeet’s patented Mixed Pulse process, an evolution of QPT (Quick Pulse Technology), is at the core of the Artsen III 500Q’s performance. This technology intelligently modulates welding current characteristics, adding short-circuit transition elements to the traditional pulsed arc. Precise control based on fast feedback loop and “chopper control” algorithms results in a lower voltage arc that is both more concentrated and more resistant to noise.

In practice, the welder experiences a significant increase in welding speed (up to more than 20% compared to standard pulse), while maintaining excellent weld quality. Concentrated arc energy provides deeper penetration, which is key when welding thicker sections and in preparing joints requiring full penetration. Significantly reduced spatter and lower propensity for defects such as underfusion or sticking minimize the need for time-consuming post-processing. In addition, the shorter droplet transition distance and process stability make it ideal for robotic and automated welding stations. Less heat build-up in the chuck’s consumable parts translates into longer life and lower operating costs.

MEGMEET Artsen III 500Q Flexible Short-circuit Transition Technology is an advanced solution dedicated to MIG/MAG welding in short-circuit mode, where it is crucial to obtain the highest quality welds with minimal spatter and low linear energy. The system is based on precise detection of the moment of formation of the liquid metal droplet constriction at the end of the electrode wire. At the critical moment, just before the droplet detaches, the patented “chopper control” technology rapidly reduces the welding current to the minimum level necessary to sustain the arc.

As a result, the metal droplet passes into the weld pool in an extremely calm and controlled manner, eliminating the violent “explosions” characteristic of traditional short-circuit passage. The result is a splash reduction of more than 70% compared to standard DC sources. Less spatter not only means a cleaner workplace and less material consumption, but most importantly, minimal cleaning of welds and welded parts. The low linear energy of the process minimizes distortion, which is particularly important when welding thin sheets (even less than 1 mm) and materials sensitive to overheating. In addition, the technology exhibits excellent gap bridging capability and is ideal for remelting layers.

The MEGMEET Artsen III 500Q is designed to integrate with modern production management systems. The device is optionally compatible with the SMARC (Smart Manufacturing Arc) platform, a smart IoT system for welding developed by Megmeet. This integration opens the door to advanced real-time monitoring of welding parameters, remote diagnostics, management of welder qualifications (e.g. via RFID cards), tracking of material consumption and archiving of process data. For companies seeking to optimize and fully control quality, SMARC provides a powerful analytical and management tool to support the Industry 4.0 concept.

Independent of SMARC integration, the Artsen III 500Q offers a built-in USB interface. This functionality allows users to easily and quickly update the device’s system software. As a company that invests heavily in research and development, Megmeet regularly improves its arc control algorithms and introduces new synergy curves and optimized welding processes. Thanks to the USB port, professionals can rest assured that their device will always be equipped with Megmeet’s latest technological advancements, which translates into continuous improvements in quality and productivity, without having to replace equipment. The device also has a memory for 99 individual welding programs (JOBs), allowing quick recall of optimized settings for repetitive tasks.

The MEGMEET Artsen III 500Q (Water-cooled Package) is designed to provide maximum performance and reliability in the most intensive industrial environments. The key component of this package is an integrated, high-performance water-cooling system. It is responsible for maintaining the optimal temperature of both the key components of the power source itself and, most importantly, the welding fixture. Efficient heat dissipation is essential for prolonged welding with high currents.

Thanks to the synergy of advanced power electronics and powerful water cooling, the Artsen III 500Q achieves an impressive duty cycle of 100% at full 500A welding current (measured at an ambient temperature of 40°C). This means the unit can run continuously at maximum performance without the risk of overheating and the need for forced stops for cooling. For professional applications in batch production, steel construction, shipbuilding or automotive, this guarantees process continuity, maximizes productivity and eliminates bottlenecks at welding stations. In addition, the cooled chuck provides greater operator comfort and prolongs the life of consumable parts.
