The TERRA 270 RC and TERRA 350 RC are robust and reliable three phase power sources for TIG DC Lift and electrode welding. This arc generation is based on tried and tested inverter technology, and dimensions are particularly compact thanks to the Three-Level® power platform. The entire welding process is digitally controlled by a DSP microprocessor. MMA power sources feature the innovative DPC (Dynamic Power Control) function that ensures intelligent control of arc current as welding conditions vary. You can also set voltage/current ratio, a particularly useful function when welding with cellulose electrodes. The same innovative design and technology as the URANOS range make TERRA power sources robust, user friendly and technically advanced, with all the essential functions for efficient and continuous operation.
