The TERRA NX 320 TLH is a simple and reliable three-phase power source for TIG DC and electrode welding. Arc generation is based on tried and tested inverter technology, and dimensions are particularly compact thanks to the Three-Level® power platform. This power source incorporates a VRD (voltage-reduction-device) to reduce no-load voltage in hazardous environment.
