The MEGMEET Artsen II PM500 AD in “Water-cooled Package” configuration is designed to maximize performance and reliability in intensive industrial applications. The water-cooling system, integrated into the 500A power source, is key to maintaining optimal operating temperatures for both the machine itself and the welding fixture.

Thanks to efficient heat dissipation, the water-cooling package makes it possible to achieve a claimed duty cycle of 60% at full 500A (at 40°C) without the risk of overheating. This is particularly important when welding with pulse methods, which generate significant thermal loads. For the professional, this means the ability to work uninterruptedly on thick sections, weld long welds and use the full current capabilities of the machine, which directly translates into increased productivity and reduced downtime. In addition, the cooled welding chuck is lighter and more ergonomic than its gas-cooled counterparts of similar load capacity, improving operator comfort.

The dual-pulse function of the MEGMEET Artsen II PM500 AD is an advanced technology that makes it possible to achieve welds of unsurpassed aesthetic and metallurgical quality, especially on hard-to-weld materials. The process involves modulating a standard pulsed current with an additional pulse at a lower frequency, resulting in a “pulse-in-pulse” effect.

When welding aluminum, dual pulse provides excellent oxide film cleaning through precisely controlled phases of positive polarity, while minimizing injected line energy. This results in a smooth, shiny weld with a clearly formed scale, free of porosity and sticking. For stainless steel, double pulse produces aesthetically pleasing welds resembling those made by TIG, with excellent fusion control and minimized thermal distortion. For the expert, double pulse is a tool for creating welds that meet the highest quality standards, reducing the need for finishing.

The MEGMEET Artsen II PM500 AD uses fully digital microprocessor control that manages all aspects of the welding process in real time. At the heart of the system are precisely developed synergistic welding lines dedicated to different combinations of weld material (carbon steel, stainless steel, aluminum), electrode wire diameter and shielding gas type.

Once the operator selects the basic parameters (e.g., material type, wire diameter, gas), the device automatically selects the optimal arc voltage, arc dynamics and other key settings depending on the set wire feed speed (or welding current). The synergistic system significantly simplifies setup and reduces the time needed to prepare for welding, minimizing the risk of errors. For the professional, this means easier achievement of high-quality welds, greater repeatability of results, and the ability to quickly adapt to different welding tasks, even for less experienced operators. The “Constant Penetration” function further stabilizes fusion depth regardless of fluctuations in the length of the free wire exit.
