MI200T – Spot Welder

MI200T – Spot Welder

Premium squeeze-type resistance spot welder with inverter head

The MI200T’s high-performance transformer pliers draw up to 40 percent less power than many cable pliers, further enhancing its energy savings and long-term cost-effectiveness. This high-efficiency design also means that the amperage service required for the MI200T is one of the lowest in the industry, typically requiring only a 40A service. In addition, the MI200T’s duty cycle is so high that the technician can operate the welder continuously without having to slow down to let the welder cool off. Liquid cooling to the tips is standard. The MI200T is specifically designed for high-strength steels such as Boron, USIBOR, TRIP, TWIP, and XIP. It has been quality tested and approved by many car manufacturers.
