The MIG 500 inverter wire feed welding machine sets the standard for professional MIG gas welding needs. It has strong control board features. Hence, there is a consistent and reliable performance in various situations. You have the option of choosing between the 100% duty cycle or the 60% duty cycle.

Firstly, the 100% duty cycle has 3-phase input voltages as follows: 208/230V, 320A/30V.

Secondly, the 60% duty cycle has 3-phase input voltages as follows: 380/400/440/460V, 500A/39V.

This three-phase inverter ensures the stability of the output voltage when the input power supply fluctuates and the arc length changes. Also, it has a self-adjusting ability which makes sure that there is a stable welding process for the entire workpiece. Therefore, the user is able to weld continuously for hours on end. In addition, it is suitable for robotic welding arm use.

Furthermore, the MIG 500 can weld together both thick and heavy parts. These parts can be 14 inches in thickness and up.

Moreover, the MIG 500 welder features long cables, a wire feeder with a compact form-factor, and a welder. The welder will roll around your workspace with ease. This ensures your ability to reach those high up, narrow, and hard to reach areas of your project. There is a reach of about 15 meters or 49 ft. The versatility of this machine is essential to industries such as shipbuilding, bridge building, pressurized vessel assembly, construction, etc.
